Mycoprotein Side Effects and Quorn Allergy Symptoms

Updated on March 22, 2013

I ate a Quorn Lasagne recently and was violently sick within two hours. I had a small suspicion that I may have a problem eating Quorn, as the last time I ate it, over a year ago, I had made a stir-fry, and had similarly been sick within a few hours.

However, I had been led to believe by Quorn over the years that its products were derived from a mushroom and therefore healthy.

Something didn't add up and I decided to find out more about Quorn.

After carrying out some initial research on the internet, I was horrified by what I found out - that Quorn is not made from a mushroom as it stated in the past, or a "vegetable protein" as currently stated but instead is made from a mould and a potentially toxic one at that.

No wonder I was so sick!

I know many vegetarians eat Quorn quite happily without side effects, but for up to 10% of people, it can cause an allergic reaction.

If Quorn is made from a mould, people need to know about it. There are some people, myself included, who are or might be allergic to mould. As a child I had an allergic reaction to Penicillin, which is a drug made from a mould, and was unable to take it.

It would help if there was a warning on the packaging, but I guess it wouldn't look very good if there was a label which said "This product is unsuitable for people who are allergic to mould".

I wanted to write this hub because I feel that the company that manufactures Quorn misleads consumers about what its products are made from and the fact that it is aware that for a minority of people, it can make them very ill, yet there is no warning of this on their packaging.




So, what is Quorn?

Back in the early 1960s, nutritionists and health experts were concerned that the predicted growth in population would mean global food and protein shortages in the future. Food scientists started a search to find new sources for food, which would help to meet the predicted increase in demand. After several years of searching around the globe, an “organism” was found occurring naturally in the soil in a field in Marlow, Buckinghamshire in the United Kingdom, which ultimately gave Marlow Foods the opportunity to develop a completely new food ingredient - Mycoprotein!

Quorn is the brand name for mycoprotein, a man made protein made from mould, a type of fungus.

  • "Myco-" is from the Greek word for fungus and Mycoprotein means protein from fungi. A fungus called Fusarium is the main source of mycoprotein and it is grown in vats using glucose syrup as food. It is entirely man made.
  • The main mycoprotein products on sale in Europe and the USA is the brand Quorn. It is manufactured by Marlow Foods in the United Kingdom, who currently market it as a meat substitute in vegetarian products such as pies, lasagnas and stir fries etc. . . .
  • Quorn has been available to consumers in the UK since the mid 1980’s and has been introduced into other countries such as the US several years later.

Studies have shown that mycoprotein leads to allergic reactions for a small minority of people taking part in research

  • The British developer of mycoprotein themselves conducted a clinical study in 1977-78 that proved that the product causes sometimes-severe gastrointestinal disturbances.
  • According to a study undertaken by CSPI, it was concluded that around 4.5% of the population are intolerant to Mycoprotein.
  • In another study, in tests by the manufacturer of Quorn products themselves, Marlow Foods, a division of the multinational pharmaceutical company AstraZeneca, it became apparent that for a small percentage of people who ate a Quorn product, they would go on to experience vomiting, nausea, or stomach aches within a matter of hours.

Therefore, the manufacturers themselves know there is a problem with the problem causing an allergic reaction but are choosing not to make the public aware by not putting warning labels on the products.



Why do people have an allergic reaction to Quorn?

  • Mycoprotein has a high protein content and allergens are usually proteins. Many people are allergic to protein foods such as peanuts and shellfish.
  • Many people also have allergies to fungi or moulds (including by inhalation) and that is why they may also react to Quorn.


Marlow Foods have also misled consumers on what their Quorn products are made from.

In the past Marlow Foods claimed that it was made from a mushroom. This was incorrect and a classic example of deceptive marketing. As a result the FDA and authorities in the United Kingdom forced Marlow Foods to change the labeling of Quorn foods, which had falsely claimed that mycoprotein was “mushroom in origin,” “mushroom protein,” or “a small, unassuming member of the mushroom family,” even though it’s made from a non-mushroom processed mould.

Marlow Foods continues with its misleading information. As of today – September 5th 2010, on Marlow Foods own website, they state that Quorn “is made with mycoprotein, a versatile, vegetable protein”.

I have eaten a wide variety of mushrooms and vegetables throughout my life, I am now 43, and have never been sick like this before.

I can only conclude that mycoprotein is not a mushroom or a healthy vegetable, as it currently states, but is indeed a mould, and for some people like myself a toxic one at that.

The particular fungus used, Fusarium venenatum, is known for producing mycotoxins. In fact, the word ‘venenatum’ is Latin for venomous.

Quorn’s manufacturer, Marlow Foods, states that the strain of fungus it uses supposedly does not produce toxins. (So why was I so sick?)


What is a Quorn Allergy?

A quorn allergy is an adverse reaction by the body's immune system to quorn or food containing quorn. The body's immune system produces immunoglobulin E (IgE - an antibody) and histamine in response to contact with the allergen

What are Quorn allergy symptoms?

Symptoms of having an allergy to Quorn / Mycoprotein include vomiting, diarrhea, hives, swelling, or even anaphylactic shock.

The symptoms come on very quickly. I was vomiting violently within a couple of hours.

In a CSPI-commissioned telephone survey of British consumers, approximately 4.5% of people who ate Quorn reported adverse reactions. CSPI’s analysed 597 reports of adverse reactions attributed to Quorn. Of those people, 67 percent suffered vomiting; 33 percent diarrhea; 6 percent hives or broken blood vessels in the gastrointestinal tract or eyes; and 1 percent anaphylactic reactions. Many people suffered repeated reactions, which helped them identify Quorn as the cause. Most of those reports were collected on a CSPI web site, www.QuornComplaints.com.

How many cases go unreported?

I consider the side effects from eating Quorn products are more widespread than we think.

Worryingly, over 500,000 Quorn meals are now eaten every day in the UK. Most people won’t initially make the connection between eating Quorn and feeling ill as it has a healthy image and will blame their symptoms on something else.

It wasn't until after the 3rd time that I ate Quorn and was sick yet again that I knew I had a problem with it - I had previously attributed the cause of vomiting to other reasons.

No one would choose to eat moldy food that makes you sick. I for one won’t be eating Quorn products again in a hurry. In my opinion, it should be banned.

So far, hundreds of people have commented on this article, saying they have also been ill after eating Quorn. See the comments section at the end.

  • As an example, say you notice that 3000 people a month search for "How to cook a chicken curry" compared to only 500 who search for "Hot Chicken Curry Recipe".
  • You call your article the most searched for phrase - "How to cook a chicken curry"
  • Include this phrase into both the title and the content of your hub.
  • Your article now stands a good chance of appearing on the first page of the Search Engines search results page, being clicked on and read.

What you are doing is finding out exactly what people want, the exact phrases they are typing into the search engines to find it, and writing articles that give them what they are looking for. You make it easy for them to find your article by using their search phrase in your title and content.

      " ...."Unlike the mushrooms that have been eaten for millennia, this is a new entrant into the human food supply. There had been remarkably little safety testing done of Quorn’s fungus, though what had been done wasn’t all that reassuring. One early company-sponsored test found that 10 percent of 200 test subjects who ate the fungus experienced nausea, vomiting, or stomach ache, compared with five percent in a control group.

      The Latin name of the fungus, Fusarium venenatum, should have tipped off regulators: venenatum means ‘venomous.’

      So now Quorn’s Toad is out of the Hole, as it were.

      This is absurd. You devoted an entire website to this.

      Many cheeses are also made with mold. You probably eat cheese all the time and *gasp* don't get sick. Just because something is made with mold, spores, or even bugs, doesn't mean it's automatically horrifying and bad for everyone. Or.. maybe you are allergic to cheese! Which is fine - and you probably don't go around devoting websites to the worldwide danger that is aged cheeses, just because of your situation.

      Some people are also allergic to chicken. (my daughter is!).. should we then label packages of chicken as having potential allergic consequences? What about garlic? (she's also allergic to that!) Since a subset of folks have garlic allergies, should we specifically label that as a warning on all foods?

      You noted that this strain of fungus or mold is stated not to produce toxin, and then consider that suspicious because you therefore can't understand why you got sick. Because your body didn't like it. Simply put. Some people are allergic to cucumbers; that doesn't mean it's poisonous or toxic. It just means your body doesn't like it, doesn't recognize it, and attacked it.

      Having an allergy to a food does not mean it's a "bad food" or dangerous. It's only bad and dangerous to your body. And in that case you shouldn't eat it. I can't believe I'm even trying to explain this. Hopefully at least one reader will see this comment and be touched with a moment of common sense.

      Sounds like my experience was completely typical. Had quorn a few times a few months ago, always struggled to sleep afterwards and suffered from wind and terrible diarrhoea the following day but didn't think much of it. Made a quorn lasagne last night and it was so much worse - I was vomiting for hours and still feel bad 24 hours later. Won't touch it again.

      I made the grand mistake of having Quorn nuggets for two nights in a row. Admittedly, I'm a bit of a lazy cook and if they sold bachelor chow in a can, I would buy it. I thought Quorn was an easy meal option. But not one hour after eating it on night 2, I felt weak and my heart rate started to race to the point that my arms were twitching with each beat. I had a horrible headache. I've felt a little fuzzy after eating it before, but this was the last straw. I've thrown the rest of it out and consider this unsafe. Luckily, I felt wiped out but survivable an hour after it started. If it had gone on, then I would have sought out emergency medical attention.

      Despite my experience, I wonder how is it that they can sell a mould in any country, and pass it off as food? Don't they know that people have mould allergies? That they are raking in cash from selling this potentially deadly product is unconscionable!

      Hi, I've been eating quorn for years and never had a problem until about 3 months ago. After eating a lasagne made with quorn I got terrible stomach cramps and pain - felt very very nauseas although not actually sick and just was awake all night thinking I was about to throw up. I felt horrible. Didn't connect it with the quorn until last night - had sausages made with quorn and the whole thing started again, only worse! On looking it up on the internet, I realised there was a connection. all the quorn in my freezer is going in the bin!

      My short experience with Quorn was not good. Sure, it tasted awesome, but I got a serious allergic reaction to it. I will mention that I have an allergy to mold, but I'm not allergic to any type of mushroom. Here's what happened to me- I only ate Quorn 3 times, but by the 3rd time there was no doubt I was allergic to it.

      1st time: mild upset stomach & irritated throat. 2nd time: indigestion, irritated mouth & throat, mild puffiness around my lips. Neither one of those times was I particularly alarmed, but did take note of it the second time. The 3rd time was far worse: in addition to the symptoms I experienced before, I started to experience swelling of my face & mouth. My husband almost took me to the ER, but didn't when the Benydryl I took seemed like it was finally starting to work. Lesson learned. I will never eat Quorn again.

      My advice is this: Do not eat Quorn if you have any type of mold allergy. It could get bad.

      Had Quorn mince twice. Both times really severe sickness and diarrhoea within a couple of hours lasting all night. Only after the second time did I make the link. I can normally eat anything and very rarely have an upset stomach. I have no known allergies to any foods or penicillin etc but do suffer from hay fever and have an allergic reaction to dust and some animals. Maybe a connection with other allergies? I certainly won't be eating it again.

      I recently bought some quorn products to try and reacted strangely but didn't attribute it to the products until I read the back of the bag which said some people have adverse reactions to it. I'm allergic to penicillin which could contribute

      I googled this today as I started eating quorn a couple of months ago thinking it was a healthy alternative to fatty meat and the first few times I was ok, then I made a batch of cottage pies to freeze and after I ate one I was violently sick 2 hours after consuming which lasted all night, i'd cleaned the oven that day with a strong oven cleaner and put it down to that, a week later it happened exactly the same again, so then I read that you shouldn't refreeze quorn so put it down to that. Last night I used a handful of quorn to make a spaghetti bolognaise for myself and ate it freshly cooked, 2 hours later I was violently vomiting for 6 hours! I am not allergic to penicillin or nuts or eggs, nothing has made me as ill as this poison and people should be warned better than some small print I found on the packet this morning stating you could have an allergic reaction to this product. I myself too believed falsely it was derived from one of my favourite foods mushrooms.

      I discovered earlier this year after 3 -4 times that I'm allergic to quorn though it feels more like I'm poisoned. My wife bless her was trying to get me to eat healthier and was mixing it in with minced meat. I thought it might be a gall bladder issue with fat so she upped the amount assuming that it would reduce the fat of the meal.

      Each attack came on faster and more severe than the last. Violent vomitting of everything for hours and the other end too. I also got a debilitating headache which went from the front of my head to the back for about 20 seconds it felt like the lining of my brain was in agony, after which I was only capable of curling up in the foetal position until the morning. Nothing makes me as ill as that stuff, I too get the jitters when I see the box I hope I never eat another piece again. Thank goodness my wife discovered the allergic reaction otherwise it would never have made that connection.

      I have had two sever reactions to Quorn that hospitalised me both times. Within ten to fifteen minutes of eating Quorn pieces I got sever upper abdomen discomfort which then over the course of about twelve hours work through my digestive tract as waves of spasms incredibly painful. Also causing bowel motions and bladder emptying as the pressure from spasms pushes everything out. Also Nausea. Treated with Morphine and Maxilon and rehydrated both times. Never going near this stuff again.

      Within 2 hours of eating a small portion of Quorn mince I started having hot flushes and feeling uneasy. I then broke out into the worst itching I have ever experienced. The itch turned into whelts and rash which covered most of my body, especially the soft areas. 4 anti histamine tabs and some cort cream later,I slowly regained my sanity. This was the first and only time Quorn will enter our house.

      Reading other people's experiences makes me think that I was lucky to have only eaten small portions of quorn and realised after two meals that it was the cause of headache, nausia, sweating, shakes, sneezing and violent vomiting which luckily only lasted about an hour. For 67 years I have had no allergies or food intolerances. Links to other allergies seem to me to be a red herring.

      Why has there been no properly reported investigations of these worrying reactions? What is the true incidence of these adverse reactions? Surely Marlow Food (Aka. RHM/ICI) are not impartial observers to assess this.

      I just don`t know how this product can still be sold let alone marketed as healthy. It took me a while to realise it was Quorne that was making me ill. I have avoided it like the plague for years, earlier though I had a bowl of some food my housemate made and an hour later I started to feel ill with stomach cramps. I looked at the packet in the bin and she had used evil quorn, this is going to be a fun night!!!! Thanks for sharing everyone, I thought I was going mad when I worked out it was this healthily product making me ill. I guess the question is now, how can we stop the product being sold without a warning label listing the side effects.

      I've just made the connection between eating quorn and my symptoms. A few weeks ago I suddenly felt weak, dizzy, hot and nauseous about 2 hours after eating a quorn spag bol. I was then violently sick and had bad stomach cramps. At the time, I just thought it was a sickness bug. Today I thought I'd try some quorn sausages for breakfast and just suffered the same symptoms again. I then made the connection and searched for 'quorn reactions' and found this article. My family have eaten the same meals with me and haven't had a reaction and I also don't suffer from any known penicillin allergy. I really think there should be some sort of warning on quorn products as this reaction is very severe and seems to be affecting a lot of people. Can't understand why this stuff is still on the shelves and I'll definitely be avoiding it again at all costs!!

      I was first ill with violent vomiting over a year and Quorn was a suspect. In the end I put it down to a blood thinning drug that I was taking at the time. I was vomiting specks of blood and my stools were very dark. I stopped taking the drug and the symptoms went away. I coincidently stopped eating Quorn. Now, year later, I have just eaten cottage pie made with Quorn mince (for the fisrt time since last year) and was violently sick with diarrhea. Isn't it about time a proper investigation was made into this?

      In a sense I'm relieved to find this article and the comments from other sufferers since it confirms my own experience. I can now make sure of avoiding Quorn and probably all other mycoprotein products.

      Like others here, I suffered acute vomiting and weakness to the point of physical collapse. Fortunately I was in a place where a wheelchair was available as I had to be scooped up off the floor and wheeled to my room. It took about 12 hours for the symptoms to go and then I was back to normal except for a certain weakness from the violence of vomiting and there was a need to reintroduce food gradually.

      I ate 3 sausages yesterday ad have never been so violently ill in all my life. Had a few cocktail sausages 2 weeks ago and did not feel well, nauseous but It went away. Then exactly 4 hrs after eating the sausages yesterday I vomited really really badly all night long. The taste of that fake smoked sausage would not go away. I will never touch that stuff ever again. What is annoying is that my vegetarian friend insists that it is so great and healthy but how can it be? poison.

      i ate quorn regularly for a year. because i had no other option. i was being fed it by a vegetarian i was staying with. at first i had no severe reaction just maybe slight diarrhoea which i didn't connect at first, then one day i had the most severe stomach cramps imaginable. i thought i may die. thankfully within a few hours it went away and never had another reaction. i believe this reaction was caused by quorn. if anyone reads this please please do NOT eat quorn, it causes some people to go into anaphalactic shock. its not worth risking it. PLUS that fact thats its made so strangely is enough to put me well off. just because you arent having a reaction doesn't mean its doing your body any good. i think it should be banned!! its a criminal food substittute!

      Ok just had QUORN for the first time and I can say that I definitely do not feel great. I am vegetarian and for the past few weeks I have been eating un-processed foods and feeling great. By boyfriend wanted to make bolognese and so I suggested it because I thought it was an innocent soy product--- OK THEN WE LOOKED AT THE INGREDIENTS. Seriously people what did you think you were eating!!! It is a TOTALLY processed food. We bought it with full understanding that it was a freaky weird and chemical product and we decided to experiment with it and see what it was like. So it came as no surprise that even though it tasted good it also tasted very sweet and salty and basically a bit like fast food. I decided never to eat it again and threw the rest out. I don't get you people who are vegetarian but fill your diets with processed chemical foods on a daily basis. Just make a vegetarian sauce next time-- that is what I told my boyfriend to do. What is the point in trying to eat healthier and then eating this crap? At least we actually decided to try it knowing what it was and so we did not have to wait for three times or five times or ten years to figure it out. GET WITH IT PEOPLE!!!

      I ate quorn products occasionally for a number of years without any problems then I had quorn pate half a tub and experienced stomach cramps for a few hours. i did not link it to the quorn but I finished the tub the following day and this time experienced cramps for 24 hours. I associated this with the pate itself rather than the quorn, so avoided it in future. On returning from a holiday we had no food in apart from quorn fillet ready meal, which I had eaten before so did not think anything of eating it, however on this occasion I was in bed for 3 days with extreme cramps in my stomach. It seemed like every time I ate quorn the effects were worse than the last time so I now avoid it at all costs. i have never vomited with it but have since read reports of people vomiting continuously for hours. I am not sure why I was ok eating it for so long and why the reaction suddenly started, but I definitely don't want to have the effects again or even worse.

      I had suspicions I was allergic to quorn after two times of eating it then having extreme stomach cramps, diarrhea and vomiting but I wasn't sure as I have a sensitive stomach anyway. Last night at a BBQ I ate a veggie burger not realising it was quorn and now I have been awake all night with the same symptoms. It's the most painful stomach cramps I've ever had and I'm exhausted, dehydrated and shaky. I will never touch quorn again.

      I ate Quorn for years with no problems. I had it a few years ago and was violently sick, thought it was a bug I had got. Several weeks later I had Quorn again with the same thing happening. I haven't eaten it for 2 years now, well until last night that is. I had a Quorn burger within a few hours I was doubled up with stomach cramps then spent the whole night vomiting. I will not be eating it again.

      Quorn was launched in South Africa in November 2013 and I started buying it a few weeks ago. I initially prepared the schnitzels and the mince for my vegetarian husband and he enjoyed them, no problem. We then moved onto the Chicken cubes/chunks prepared in a sauce, also no problem. THEN - last week I made him hotdogs with the Viennas and within 3 hours, he was vomitting. I did not think it was Quorn and put it down to a tummy bug. This past Sunday evening, I prepared the cubes again in a gravy and again within 3 hours, he was vomitting, but this time it was severe and went on for ages. I finally connected the dots and googled yesterday to see if anyone else had complained about Quorn online. Oh my word, I was shocked to see that the internet is filled with people saying how ill Quorn made them. I have contacted the Head Office here in South Africa and explained my concerns as they need to adjust the packaging to not just say that Mycoprotein can cause intolerance. Severe vomiting is not just an intolerance, it is an allergic reaction. I did not even know what Mycoprotein was until I ran a search on it yesterday! My hubbie is allergic to Penicillin, so I do not believe this is a coincidence. We will not be purchasing any Quorn products from now on and will be making our vegetarian friends aware of the possible dangers.

      Had quorn several times before with no memorable reactions, so never thought twice about the fact I am allergic to mushrooms. 9 days ago, for the first time in 33 years, I thought I had food poisoning as i actually vomited. Not something I do. It was about 5 hours after eating quorn. Didn't think it was that at all. Yesterday, I had quorn again and within 2 hours was violently ill. Once it is out of my system I am fine, though I did sleep for several hours after leaving work yesterday afternoon. Today I have found several sites where people discuss these types of reactions to quorn and I know I won't be touching it again. I eat blue cheese, so it never occurred to me mold would be a problem. Never had penicillin, so can't comment there, but I am definitely not allergic to dairy or eggs... Thanks for this post and the subsequent comments. Sad to see so many people so adversely affected by a "health" product.

      I ate quorn twice and on both occasions was very sick after two hours. I realised it was the quorn after the second time I ate it. I won't touch the stuff now and don't let my family eat it either.

      According to the manufacturers website my reaction is very very rare. Doesn't appear so rare to me!

      My husband and I are both vegetarian (ovo-lacto-pesc-vegetarian) and have eaten Quorn regularly as an alternative source of protein for a number of years. Admittedly, I do not particularly like the taste or texture of it but have not noticed too much of a problem although I don't feel particularly great after eating it. However, the last couple of times I've eaten it, I have had very bad (almost debilitating) stomach cramps. The following morning I also had diarrhea. I ate the mince and although I did not react in the same way as some of these other poor people on here I will avoid this in the future.

      im absolutely disgusted that this product is not labeled clear enough, who would no what the f mycoprotine is?

      quorn needs to do something about this, it is very hazardous to some people.

      Hey everyone,

      I was really excited when we finally started having more supermarkets selling Quorn here in Germany as I had fallen in love with the products last time I was in England.

      Everything was fine the first few times but two weeks ago I had Quorn lasagna and was incredibly sick (vomiting and all) afterwards. I didn't suspect the lasagna since nobody else had been sick.

      Today I made myself some pasta with Quorn sauce and only three hours later the nausea is back full swing.

      I loved Quorn. I hate being allergic to it but after everything I have read here I won't try again...

      I have no known food allergies, can eat eggs, love peanuts, take paracetamol,the proverbial cast iron stomach, never missed a day of work through illness. Two weeks ago we had Quorn in an Indian sauce, later that night I was so violently sick I had sore ribs for 3 days afterwards, I put it down to a 24hr bug. Last night I had Quorn mince in a chilli dish. Same reaction. I was only told this morning that I had eaten Quorn last night as I assumed it was normal minced beef.

      The first time I tried Quorn I was so impressed! A "mushroom-based " fungus that's a healthy meat alternative AND cheaper than meat! What's not to love? Turns out everything! I had severe cramps and broke out in a sweat the second time I ate the stuff and then last night I was actually sick. It was horrible. After reading about other people also having a bad reaction I'm 100% certain it was the Quorn. I'm not intolerant to anything and I will eat just about everything within reason so being so ill on this stuff was a genuine shock. I've thrown the left overs away and I will certainly NEVER eat it again! I will also be checking other meat substitute foods to ensure they don't contain "mycoprotien".

      Even my jar of peanut butter has an allergen statement on it - surely the same should apply for this product. Like many other people it took me three times to figure out it was Quorn making me ill but I am really worried about accidentally ingesting it again from an unexpected source. I was so crook this time I don't want to think what might happen if I had it again.

      I still eat my peanut butter, despite the allergy warning and I'm sure people would still eat Quorn if it had such a warning. At least it would be an informed decision.

      had a quorn meal two days ago and was vomiting violently within 3 hours. Casting my mind back I realised that the only time I had ever experienced this kind of food poisoning in the last 20 years or so was having consumed quorn sausages. On the first occasion I assumed that the cause must have been an unrelated bug. However, I now know that quorn poisoning must be responsible as the reaction was so swift and violent. I have subsequently researched this subject and realise that quorn allergy is a real problem for a significant proportion of the population. Surely it is time for the food standards agency to insist on a warning to be displayed on all quorn products.

      I am a registered nurse, I have no allergies, I take no medications for anything, I have no disease or illness, and have never experienced any adverse reactions from anything I have eaten in my entire existence and went into severe anaphylactic shock the third time I ate Quorn Grounds AND ALMOST DIED HAD PARAMEDICS NOT MADE IT TO MY HOUSE IN TIME TO RUSH ME TO THE EMERGENCY ROOM! The first time I ate Quorn Grounds I had no reactions. The second time I ate Quorn Grounds I felt "not right", tightness in chest, slight tingling in my face and neck, stomach felt queasy, but I attributed it to a meat burger I had earlier in the day and blamed that instead of this "healthy meatless and soyless" product. I slept it off and woke up okay. The third time I ate Quorn Grounds was January 2nd, 2014 at 3:30 am and about 10-20 minutes later I noticed the tingling sensation in my hands, feet, neck, and face. My heart was racing, I felt light headed, my blood pressure was dropping. I began to feel itchy so I got up and looked at myself in the mirror and was HORRIFIED to see my entire body red and covered in RASHES. I stared at my reflection and noticed that my lips were swelling, my eyes were swelling so much that I could barely see out of them, my hands, tongue. and then my throat began to swell and I could barely see since my eyes were so swollen but I finally found my home phone and called 911.This all happened within a matter of minutes. I could barely talk to the operator because my tongue and throat was so swollen and I fainted shortly before firefighters and paramedics reached my house. Had it been a few minutes later, it might have been too late for me and I probably wouldn't be here writing you this message to tell you about my experience and hopefully raise awareness of this product and the possible complications from consuming it. Thankfully the doctor and nurses saved my life and about two hours after the symptoms subsided, the symptoms came back and they gave me more medications and kept me for observation for several more hours. This has been the scariest situation I have ever experienced and I now have to carry an Epinephrine pen with me at all times for the rest of my life should I ever have another allergic reaction because once you have an allergic reaction, you are at risk of having another one. Consumers should be warned about this ingredient "mycoprotein" which comes from the mold Fusarium venenatum (venenatum is Latin for filled with venom!) that is used in Quorn products. I understand that not everyone will have an adverse reaction to consuming mycoprotein, same as how not everyone will have an allergic reaction to peanuts, eggs, etc, but there should be some warning on the product package itself or displayed where the product is located in the store because had there been some warning about this new ingredient that I have never tried before - I NEVER would have purchased it or I would have done a quick online search of this ingredient that states an allergic reaction might occur. I don't know what changes will be made, if at all, from sharing my story with you, but I hope that no one will ever have to go through what I did and that I pray that their outcome isn't a fatal one and I urge that something should be done. I am not a vegetarian, I am not vegan, I am not on any special diet, I consume wheat, shellfish, eggs, gluten, peanuts, milk, etc, but my fiancé is a vegetarian and wanted to try this new product. Mycoprotein is a fairly new allergen that most people, like myself, know nothing about until they become sick from consuming it. If more people actually tried this product then maybe the percentages of adverse reactions would be higher if they reported it - if they even know that it was Quorn that caused it. I can only imagine how many unreported cases there are. I have many carnivorous friends who don't care to try "fake meat", but if they did try it, maybe they would have the same outcome as I did... but I will NEVER recommend this product to ANYONE. I'm just a stranger, someone behind a computer screen that you can't put a face with the name and know nothing about other than what I've disclosed in this message, but what happened to me can happen to someone you love or kill them... and why would you wait to do something about it then after the fact? I'm not asking to have Quorn products removed from store shelves, but simply some sort of warning should be displayed on the packages themselves or in the store in the location the products are sold.

      * Man-made.

      * Don't be fooled by someone who calls herself a 'Nutritionist' (sic).

      * If it's potentially toxic / can have cumulative toxicity, as mentioned over and over again, it should be avoided - any sane person would advise that.

      I for many years have also eaten the product, with apparently no side effects, until a couple of days ago! The only thing that made me think that Quorn might be the cause was that I cooked it for myself and my parents. My mother was fine, but my father ( who has never eaten it before) and I had exactly the same symptoms, at exactly the same time. It couldn't be food poisoning as my mother had no issues.

      We both awoke to cramps, the loosest stools he or I have ever had, dizziness, hot flushes and nausea.

      It's two days ago, and I still feel weak. I count myself lucky that it was not as sever as some people, however I too was led to believe that it was a harmless mushroom based product. It's not! It's mould!!!

      In fact, it kinda reminds me of the film Soylent Green. Although hopefully it's not really made from people.

      It's time that we did away with these heavily processed foods. We need to go back to nature, not invent stuff from a potentially toxic mould.

      I'm now thinking that perhaps my so called diagnosis of Fibromyalgia, and it's increased symptoms over the last 3 to 4 years could be that I have been cooking this stuff on a regular basis. My girlfriend is vegetarian, and so when I cook for her quorn is or more accurately was on the menu.

      I will not be eating this product again, after all I have read, and I will be warning people about the true nature of this myco protein. I had no idea that so many people were so affected, or that the manufactures know it can cause many people, many different issues.

      Perhaps I have been slowly poisoning myself over an extended period of time.

      I'd be interested to hear from anyone who has issues with this product dean.shulton@gmail.com.

      I am in the U.K.

      I live in South Africa and discovered Quorn for the first time about a month ago... It was great the first few times I ate it but I noticed I was increasingly nauseous after each meal (I attributed this to some type of stomach bug that was maybe doing the rounds and was optimistic it would pass)... alas the final nail came last night when I at quorn mince and was nauseous within an hour followed by violent vomiting, stomach cramps and upset stomach. Having done some research and having made the connection, I will never eat this stuff again. I am allergic to penicillin and suspect that was what caused my reaction. There should be a clear warning on this so-called "food"

      To the people commenting about how Quorn is safe to eat and they have had no problems at all- I was one of you! I ate Quorn regularly for years and told tons of people to try it - told people who said it was bad that they were wrong.

      Most people have acute reactions within a few hours from eating it. I had no noticeable reaction. But as time passed I became increasingly more tired and sick. So sick to the point were I couldn't function normally. After going to my doctor she determined that the cause was the Quorn.

      This is because Quorn is mold and mold is toxic to everyone.

      If you are eating Quorn and find yourself feeling sick - but can't figure out why - it might be from the Quorn. I stopped eating it over a year ago but I am still sick! Slowly recovering.

      I've read these comments with interest as I developed a severe reaction to Quorn about 16 years ago (I'm British!) and have tried to avoid the product as much as possible since.

      I needed to have an endoscope as they wanted to see if I had an alcer from the severe pains I was having. Interestingly, the side effects of eating Quorn made be severely sensitive to ANY foods for a few months after I stopped eating it. I suffered from bouts of cramps and bloating after eating Quorn until it passed through my digestional tract.

      Now I see this product being increased in the supermarket and our local hospital uses it as a meat substitute.

      It's becoming more difficult to avoid and I always question what the burgers are made of at local BBQ's in case I inadvertently eat it again.

      My husband and daughter also react to it. That's a higher statistic than one we are led to believe! My daughter is allergic to penicillin but neither my husband and I are.

      I was also told when I described this as an intollerance that any reaction to something is an allergy. It plays down the reaction which of course can increase in reaction each time you are exposed to it, and may end up being anaphylactic. Make sure you describe this as an allergy so it's treated seriously by others around you.

      It makes me feel better to know I am not alone in what I suffered after eating these products. Like many others, I had eaten Quorn products in the past with no known issues that I can recall. Then about three years ago I had a Quorn patty for dinner and an hour or so later had my head in the toilet. I was sick a good portion of that night, but I chalked it up to a stomach bug. Either way, I didn't eat any other products until a few months ago when I noticed them on sale at the store. Unfortunately, I chose to have another patty for lunch when I was home alone with my baby girl. An hour or so after eating, I felt weird and tingly, then started having major hot flashes, and then was violently ill for a few hours. I felt horrible having to keep my poor daughter in her bouncy seat next to the toilet so I could watch her while I was sick. Great for people who can still eat their products, though I would advise to eat with caution since the reaction seems to creep up on you over time, but there needs to be some sort of warning on these. I won't be eating any of their products again.

      My adult son recovering from leukemia made violetenly sick from Quorn products I made tacos one night ( using the ground beef Quorn) and within 3 hours he was violently ill. I did not connect it with the Quorn product at that time. Then a week later had their stuffed chicken breast (quorn product) and once again within hours he was violently sick. When I realized that both times he had eaten this product I started an internet search and found this article. I think it is horrible that Quorn does not tell people. A person recovering from leukemia already has an immune system that has been compromised, this could have killed him!!! I am outraged and throwing out ther rest of there product that I have in my freezer! Shame on this company for no warning on their labels.

      Bratman, you're wrong - 'us British' can't all eat it without a reaction. I've eaten it 3 times with the end result being hours of violent vomiting and diarrhea, followed by 2 days of muscle pain and exhaustion from the ordeal my body had gone through.

      I only made the connection after the 3rd time of eating (which was also the worst reaction), thinking it unlikely that I would have gotten sick from something made from mushrooms. I only discovered the truth of Quorn after searching online and finding other people with the same story as me. So Bratman, just because you didn't get ill doesn't mean there aren't others who did.

      I live in Norway now, where nobody seems to have heard of Quorn - I sincerely hope it remains that way.

      Strange how Americans and Aussies are submitted to a negative reaction to Qourn but us British can eat it without symptoms. I used to eat it all the time when I was a vegetarian, now I'm vegan I've found more sources of natural protein and cut Qourn out. Just for the record I never got ill from any Qourn products and neither did my girlfriend, friends or family.

      Maybe because it comes from British soil foreign bodies aren't ready for it?

      I first ate this in the 1980's and it took 3 times before I realised it was Quorn that was making me violently sick. I wrote to Marlow and they offered to fund me travelling to London to have a general allergy test. They didn't show me the results but said they were negative! I have since eaten Quorn twice unknowingly and also become violently ill.

      I was told 1 in 65 people are allergic to it.

      My mother is allergic to penicillin, so possibly some connection there.

I should have questioned them but risked it and it was obviously a quorn burger as I have paid the price today! I was awake all night feeling sick and with stomach cramp.

      After suffering with cancer, I thought I would try to eat less red meat and consume more veggies to help my body to recover from chemo. I have now been very ill twice after eating Quorn mince. I wasn't sick but had terrible stomach pains and diaorrhea. I thought it was a vegetable protein, maybe soya, and couldn't understand why I could eat other pulses with no problem. I was horrified when I discovered it was a mould and also possibly contains toxins. Shall be avoiding this in the future. Interestingly, after cancer treatment I have also become allergic to penicillin, only mention this as I saw some others who were intolerant also had a penicillin allergy. Just goes to show, you need to read the packet and do your homework. I am too trusting of food manufacturers.

      My family has eaten Quorn for years, both in the UK and Australia and have never had any issues at all. We have Quorn 2/3 times every week. Whilst some people may be allergic to Quorn, maybe because there may be gluten or egg in it rather than the mycoprotein itself, most are not allergic and benefit from this meat alternative. Maybe sometimes people got sick from the other food in the meal or from an earlier meal. Food poisoning may appear the next day after a meal, and that will be the case with some of above. Look up Wiki and you will see the alternative, red meat is much worse for you, and sometimes permanent.

      Hi, like so many others I found your page when trying to find out what had happened to me. I had eaten quorn mince and two hours later was violently sick, skin flushed and with awful cramping. I too had a similar experience with quorn about ten years ago but failed to connect the two. I'm not allergic to penicillin , but my reaction to the quorn was just plain scary, I'm concerned that with no way of ascertaining who is vulnerable to reaction, there should be warnings on packaging. People who are immune compromised or vulnerable in other ways should be advised of the risk, I shudder to think if I had given this to my 12 month old child

      I'm absolutely amazed at this site and the responses to it. It's a revelation! Thanks so much for providing this illuminating information.

      I ate Quorn on very few occasions years ago and cannot say that I noticed anything untoward. Recently I have tried it again and made a couple of evening meals with it.

      After the first meal I awoke in the middle of the night, my heart thumping and my mind racing. No headache, no vomiting, no sweats, but a strange wide-awakeness; I wondered if it could have been the Quorn but as it seemed to be such an innocuous substance I didn't give it much credence. However, I decided to wait a couple of weeks and try again, just to see.

      Last night, within a couple of hours of eating the Quorn my stomach was complaining, I had some diarrhoea but didn't feel sick. However, I lay awake until 2am experiencing the same frantic symptoms of heart pounding and over-stimulated brain as before. My gut is still not right.

      I have already concluded that it was the Quorn and decided to steer clear in the future. This led me on to looking into the substance to learn precisely what it was - like many, I had always thought it to be mushroom based.

      Reading other people's experiences it seems to me that a problematic response to Quorn can be accumulative - for some, the first few times are Ok...then the full and unpleasant picture appears with subsequent exposures to it.

      I will avoid it from now on - I'm lucky enough to have recognised the warnings!

      Interestingly, I'm allergic to most antibiotics, including penicillins.

      I was so excited to find Quorn products (UK) were actually palatable and spent a good week enjoying quite a lot of them. I had a terrible reaction - I was completely fatigued and could not functio cognitively. Exhaustion. I felt sicker each day and reviewed what I was eating as I was otherwise healthy and the only new addition had been the Quorn. I immediately eradicated them and three days later was back to normal. I never TOUCH them now. It should be clearly labelled as artificially/laboratory created as I wouldn't have touched the stuff had I not thought it was mushroom based. This article is great. I also think the nutritionist's perspective is irrelevant really - rather imposing - when there's so many of us here feeling so unwell, the ''terminology'' we select to use, is unimportant, neither is ''preserving'' the Quorn brand's reputation high on my list, which makes me think he was unlikely to be a nutritionist and more likely a Quorn marketing manager.

      After eating Quorn several times I came to realise that it made me ill. I stopped eating it. However, I inadvertently ate quorn in a meal whilst dining out and within two hours, was in hospital. I completely lost consciousness in addition to all the effects listed above by other people. When I regained consciousness, I informed both the ambulance and hospital staff of the cause. No one had heard of any other reported difficulties.

      It took me over week to recover!

      I've had Quorn 4 times and violently sick each time -- embarrassed that it took so long to make the connection. Have never had any other food or penicillin allergy, so, in spite of the (small) warning label, I didn't really think of the Quorn as the culprit. Husband and son had no ill effects. Mostly just glad to have my experience validated here, as the hospital rather pooh-poohed the whole thing. Thanks for making all of these comments available.

      I have eaten Quorn four times.

      After the first two I felt queasy, last week I had violent vomiting after eating the schnitzel product and today after lunch of tacos made with Quorn mince I have been vomiting all afternoon.

      I have never reacted badly to foods in the past and can eat all sorts of mushrooms, moulds in cheeses and have always had a strong digestive system but I will never touch this product again !!

      On the back of quorn in the UK it actually says "quorn is made of myoprotein and is high in fibre and protein which may cause allergies in some people" :)

      I too vomited 4 hours after eating Quorn products. This happened twice so I am very confident it was the Quorn that caused the reaction.

      I really wish I'd spotted this article before I bought Quorn products. For me it's a similar story. Tried it twice and no problem. This was the Quorn mince and yesterday I had the Quorn Southern Style Burgers and within in a couple of hours I became violently ill. Started with sweat breaking out and nausea followed by vomiting and diarrhoea. Feeling better today though so i'm glad for that but I will not even touch these products again. Now, here in australia it does say on the package; "Quorn foods are made with mycoprotein, from a nutritious member of the fungi family. Mycoprotein is high in protein and fibre. This may cause an intolerance in some people". I have eaten high protein foods and high fibre foods before and can tell you that I have never became violently ill like last night or felt any discomfort whatsoever. So it is fair to say that I did not feel at all alarmed by this message on the box. Now I know what the real cause could be I find this message misleading. And I have to agree that this product should either have a proper description of contents and side effects or should be banned.

      Hello. I have studied nutrition extensively over the past 20 years (referring to Bobble's comment quite awhile back) and would like to add my 2 cents worth.

      NOT all allergies will show up in a Dr's test - very often allergies are at an early stage and therefore won't be detected. Also, unless the Dr can test for a specific substance, you may not get an accurate result. I.E. you may be tested for an allergy to moulds etc however that may or may not indicate your reaction to the specific substance in Quorn products. I say this as I truly believe that we must listen to our bodies first and foremost.

      If I may add to this thread with my experience .... I ate Quorn last night for the first time, the result was horrific. All the more so because i'm currently pregnant and the reaction I had could have harmed my unborn baby. I'm flabbergasted that this product doesn't have clear and concise information on it's packaging. I'm highly allergic to penicillen, as is my 5 yr old son, and i'm now guessing my 12 month old son, who also ate Quorn last night and were violently ill as a result.

      It's pure negligence on the behalf of the manufacturers - how long will it be before a more extreme reaction occurs? How many extreme reactions will it take before the manufacturers are forced to act responsibly????

      I had a BBQ on sunday and whilst the rest of my housemates ate meat and drank, I made a few jokes about them being drunken boys and that the meat will probably end up undercooked and make them ill. It was actually me throwing up violently the rest of Sunday night! It's now wednesday and I am still feeling to vulnerable to eat properly again and very delirious. This is a very interesting, yet slightly scary article! Being a veggie since I was about 6 I have eaten Quorn for years and years. This is the first time I have had any issues with it, if it is down to this, which seems now quite likely. I was the only one out of 6 to get ill, when we all ate exactly the same except I had Quorn burgers instead of meat, I have been going on at them for the fact that Quorn can't make you ill as it is so good for you, but obviously I should do some more research. What do us veggies do now? :(

      I had a quorn product for the second time today, the first time (about a month ago) i felt very nauseus but wasn't sick and thought nothing of it, today about 2 hours after eating it suffered from V&D with stomach cramps, which went after about 3 hours. I am intolerant to goats cheese and this had exactly the same effect on me! A warning on the packaging would have stopped me from purchasing this product in the first place!

      I've been eating quorn ever since it came out in the UK so for many many years now. My immediate family stopped eating it a few years back after one of them reacted badly to it but I was always fine. A few months ago I tried the quorn bacon style rashers and experienced severe stomach cramping and diarrhoea, thought it was coincidence but when I tried the same product again, exactly the same symptoms cropped up. I then thought it may just be that product but I had the quorn frozen sausages last night and experienced exactly the same. I am not allergic to penicillin though one of my children is, he is fine with quorn. I am intolerant to soya though which means my choice in veggie alternatives was already severely limited.

      Iv been eating the product for 12 years and thankfully have never had any problems. I feed it to my family about four times a week and we all love it.

      I wish they sold as many items here as they do in England.

      I will gladly take any coupons going :)

      Firstly - thanks for writing this hub and making it so easy to find in the google search!

      Well, you can add my name to the list - as I just joined "the club". I may have eaten a quorn product at some time in distant past, but recently deliberately bought a product with the plan to eat it on a more regular basis ... and I too (foolishly) thought that the "mycoprotein" meant it was a mushroom derivative (what a fool!). First time I ate it, I felt a little unwell, but put it down to other factors (cold, tired, long day). Second time, felt similar and suspected there was something up ... but unknowingly went back for a third try yesterday. Within a couple of hours I was feeling nausea and a bit wooly-headed ... Four hours after eating the product I was violently sick and had severe diarrhoea. Needless to say the rest of the product will be going in the bin. I actually get a similar reaction to a rather well known pasta sauce, which kind of makes you wonder about the way they've listed the ingredients ... (and believe me - I'm not an allergy or food intolerance type of person - I'm healthy and have the constitution of cast iron!) ...

      Thanks again for the heads-up ... now instead of being lazy and using a packaged "veggie burger", I will have to make my own - so that I know it contains veggies such as mushrooms and not mould!

      Severe Itching & Swelling is what is happening to me at this moment! Ive bought and eaten Quorn chicken chunks about 10 times in the past and I ate two Chicken patties last night and about an hour later I was itching all over and swelling of my lips. I had no idea it might be the Quorn until I narrowed down that that was all I ate. I have no food allergies at all. I guess I am allergic to mold, as Im sure most people are. I took some allergy tabs last night so I could sleep and now I am having another flair up getting itchy and blotchy and swelling. Im so disappointed because I am a vegetarian and was hoping that Quorn would be a great meat substitute for most my meals. Guess not. I do wonder how many people are out there having adverse reactions and not knowing its the Quorn to blame. So glad I did some research!! Sorry Quorn, wont be buying you again.

      My daughter who is veggie and a good cookmade me a nice chilli a while back with Quorm that night I was so ill with D@V stomach cramps and server sweating and felt terrible not had any again until last night chilli again made with Quorn well again I was so ill I had to call my daughter to come and at one stage I could not breathe we thought we would have to call an ambulance and again the D@V continued for several hours my daughter stayed the night with me and this morning I feel like I have gone 12 rounds with Mike Tyson. I have just found this site and just wanted to add my experience with you all, but will not be eating Quorn again although my daughter is fine and is relieved that she did not poison me.

      These experiences are all so similar to mine about 12 years ago and I haven't touched Quorn since. The first and second time I was very sick a few hours later and didn't link it to the Quorn - maybe it was the glass of wine or the cheese or something... The third time I was projectile vomiting and hyperventilating instantly and couldn't move for hours and I finally realised why. On a later occasion I was sick after simply eating meat cooked on the same grill as Quorn. My partner at the time was using it because he wanted to eat 'healthier', but I'll be sticking to meat. I wouldn't dare touch anything vegetarian in a cafe after that.

      My husband had several occasions of vomiting at family gatherings that we put down to a sickness bug caught from the children.On a recent occasion we had all had the same food,he was the only person to be sick and we thought that quorn might be something to do with it.I looked it up online and I was amazed at the number of people who had had similar reactions,needless to say he will be giving quorn a wide berth from now on.

      I have known I had a Quorn allergy / intolerance for many years, but didn't realise how common it was.

      The first couple of times I had it, I ended up in A&E with such severe vomiting that finally I was retching then passing out each time. I didn't associate my symptoms with Quorn initially, thinking as I guess most people do, that as it was made from mushroom protein and I can eat mushrooms that it could only be some kind of bug. On the 3rd occasion, I realised that there must be some connection and since then I have never knowingly eaten it. However, as I have been a veggie for 22 years, I do occasionally get given Quorn without me realising. On each occasion, I have been very, very unwell afterwards.

      I am form the UK

      I can't tell you how ill I am after eating Quorn - but what I hadn't realised until today it that it's not an unknown phenomenum in other people too. I had belived that Quorn is made form mushrooms and I LOVE them. I am however very allergic to penillin. I made the link about not being able to tolerate Quorn just like the author after several bouts of hideous illness after eating Quorn products (dreadful and almost instant diarhorrea, a horrid feeling of being totally bloated with stomach pains and headache, passing out, uncontrollable projectile vomiting and then feeling dreadful for 2-3 days) and so check ingredients VERY carefully. Worryingly twice recently I have had similar symptoms after eating mince based products which didn't mention containing any mycroportien - but which I would swear from how I felt actually contained this vile and evil stuff.

      Just last week I was so ill in the middle of a west end show in London after having eaten a pre-show meal of lasagne that the theatre staff called an ambulance!

      The restaurant denied that the lasagne had contained anything other than minced steak but I'm pretty sure I know different.

      I am vege so find that Quorn mince is essential in making chilli / bolgnese etc. it doesn't make me sick, however I do get a terrible stomach the following day, going up to 7-8 times with diarrhea. It's not pleasant and is deifnatly after every time i eat quorn without any doubt.

      Like so many of the comments above I had only had Quorn about 3 times... and had an upset stomach after each occurrence but didn't link it back to the Quorn. Then last night I ate Quorn Cumberland Sausages and within two hours was violently ill and vomiting. This went on for about two hours and then I got diarrhoea which has continued throughout the night and next day. I thought I must've had a gastro bug until I looked up Quorn on the net today and have found that many people have had the same reaction. Had I have done my research properly before I would never have eaten it.

      I agree that the small warning on the packaging 'Contains egg, milk, barley & wheat gluten. This may cause intolerance in some people.' is not enough. I am not allergic to any of those products and yet I became very ill after eating Quorn so obviously it is the Mycoprotein that is the issue.

      My other concern is the number of people that develop a worse reaction after having it a few times... what does this mean for people that haven't made the connection? I agree with the comment above- I am worried that it will kill someone one day.

      I ate half of a southern style chicken burger quorn thing a while ago, woke up half way through the night choking on my own vomit, I ran to the bathroom and then spent 4 hours vomiting and heaving up the water I was drinking from the tap- I collapsed, could not call for help, could not walk and felt like I was ridiculously drunk- I honestly thought I was going to die! I woke up the next day on the bathroom tiles , in shock, had slept through work, and had to take the rest of the day off work, was very sore in the abs for the next 2 days from the constant heaving! The crazy thing is i didn't even make the connection 4 days later when I ate the other half!!! I had to read the bloody warning in a book about the GI diet!!! It finally all made sense- I checked the package and it had the smallest warning on it- "may cause intolerances" - as far as I am concerned an intolerance doesn't make your bloody life flash before your eyes! Am disgusted this crap isbeing marketed as akin to mushrooms! ( the reason I bought it in the first place) . I have no known food specific allergies nor am I allergic to penicillin . It's awful and I shudder to think this man made junk will kill someone one of these days.

      I have just read the comments on here and I would like to thank you all. Now I know I am not going mad. I had Quorn as part of a low fat diet for the first time a week or 2 ago. First my hands began to swell and the skin peeled off. I had no way of connecting it to Quorn. I then had it again on Friday. On Friday, I had Quorn mince. Soon after I was projectile vomiting. I put it down to eating too much as I am on a diet. On Sunday, I had a Quorn fillet with a baked potato. I was then violently ill. And this didn't stop to 2/3 of the next day. I will NEVER eat this again and I will make sure everyone I know is aware of the reaction I've had.

      I realised that I am allergic to Quorn a number of years ago after the third time of eating it and being violently sick within a couple of hours. I am concerned to see that it is regularly used as a vegetarian option in school dinners where I live in Cornwall.

      Thank you for posting this. I am allergic to penicillin and recently was also excited to see Quorn for sale in Australia. I ate Quorn last night and have since had stomach cramps and the runs. No vomiting. It was only now that I remembered being sick once when I lived overseas and someone fed me Quorn.

      Just worked out that the violent v and d headache hot and cold sweats ihad last night and the previous Friday night were after eating quorn. Still feel as if I've been kicked in the stomach and have a really really bad headache today. I was appalled to find out what it is made of. There should be a warning, it looks to me by the number of comments here alone never mind other sites, and where it hasn't been reported that a full scale study is needed, not just giving it to people once but over a number of occasions, and not just a couple of hundred. It took 4 times before I was sick.

      Thank goodness for this site.

      I tried Quorn 2 weeks ago after being recommended by a friend. About 5 hours later, I was vommitting severely and sick all night. As a strict vegetarian for many years, I thought my body didn't like the texture of the mince, but didn't think much of it.

      Last night, I tried the cheese and spinach schnitzels. Once again, 5 hours later I was violently vommitting. This time I was much worse and at one stage thought I would need to go to hospital. I have never felt so ill in my life.

      I was quite concerned that there was something wrong with me until I found this site. As a child, I had an allergic reaction to penicillin and have never had it since. Obviously, I am allergric to the mould that this product is made from.

      I am shocked and alarmed that this product is allowed to be sold in Australia and/or that there is no sufficient warning. There is a very small footnote listed on the back of pack, near the nutritional information. It reads as, "Quorn foods are made with mycoprotein, from a nutritious member of the fungi family. Mycoprotein is high in protein and fibre. This may cause an intolerance in some people."

      I bought this product at Coles and will be contacting them to inform them what has happened to me.
