Bloom on Farm Fresh Eggs: Interesting Facts
Fresh, organic eggs from pasture-fed hens are quite different from their factory-farmed counterparts. A protective layer called the "bloom" has been washed off the eggs you buy in a grocery store, leaving the egg vulnerable to bacteria and a shorter shelf life. This article is a short introduction to the benefits of eggs with their bloom. Get to know your eggs!
A Momma Hen's Final Protection
Just before a hen lays her egg, her body adds the last and most protective coating to the shell: the bloom. The bloom is wet when applied, and quickly dries when it lands in a nest. Most farmers who keep eggs for themselves leave this protective coating on the egg. It is a protective shield, covering all the pores, so bacteria and outside gases or chemicals cannot enter the egg while also trapping moisture inside the egg. The result is a full, rich egg with a bright orange yolk. In fact, the bloom on a fresh egg is so protective that eggs which still have their bloom can be left out at room temperature and still be edible; however, once the egg is washed or wiped down too hard, the bloom is gone and the egg needs to be refrigerated. Ever wonder why eggs in Europe aren't refrigerated? They still have their blooms!
What Are the Differences Between Store-Bought Eggs and Farm Fresh Eggs with their Bloom?
A farm-fresh egg that still has its bloom can be kept at room temperature for up to three months and will still contain all its high quality nutrients. The yolk will be a bright orange and the albumen, the soft, jelly-like substance surrounding the yolk, will have a slight cloudy look to it. This is a reaction with carbon dioxide and proves the egg to be fresh.
A store-bought egg has the bloom washed off. Some manufacturers will go a step further and rinse their eggs in a chemical wash. Unfortunately, this means that chemicals seep into the pores which are no longer protected by a bloom. A reaction takes place. The yoke inside the shell will start to pale and shrink; the albumen, supposed to be cloudy due to the healthy exchange with carbon dioxide, will start to become clear. The more clear your egg white, the less fresh it is.
The nutrient quality between store-bought eggs and farm fresh eggs is startling. Pasture-raised eggs are 10% less fatty than store-bought counterparts. The organic, farm-fresh, pasture-fed eggs also contain 34% less cholesterol, 40% more vitamin A, and 400% more omega-3 fatty acids.* An egg from a pastured hen also has 30% more vitamin E** and produce positive HDL or good cholesterol and lower “bad” triglycerides.*** Need more? Eggs are the only food that contain Vitamin D, which is greater and healthier in a pasture-fed, organic egg.
Once the bloom is washed off, however, all those nutrients begin to weaken and degrade; the egg is at risk of being contaminated.

Where Do I Get Them and How Do I Store Them?
Many farmer's markets will have a farmer raising chickens. Some laws require that they wash the eggs before being sold, but some do not. It helps to find someone who raises their own chickens and ask if you can have some (it may be illegal for them to sell them to you, so be sure you aren't breaking any laws). Don't like the hassle? Why not look into raising your own chickens just for the eggs! This is becoming a more popular trend among urbanites in particular, who are finding it more and more difficult to buy quality fresh foods in their urban settings.
If you do find some pasture-fed, organic eggs that still have their bloom, you do not need to refrigerate them right away, which is handy if you are a baker and need those eggs to be room temperature. Storing them in the fridge will not hurt, and you can keep them even longer. Store them in a closed container to help maintain freshness. Don't wash the eggs until you are about to cook with them, and as with any food handling, wash your hands thoroughly!
