I'll tell you a story I heard from a former butcher in Sligo, Ireland.
Once upon a time, at the end of the day, butchers would pour boiling water over their butcher's blocks, and then sand them down a bit before closing the shop. Then the Irish government passed a law that all butcher's blocks had to be made of plastic. It was thought that microbes were hiding in the wood and making people ill.
So the butchers started using plastic blocks to cut their meat on, and while they still poured water over them at the end of the day, they couldn't really sand them. Well, the microbes hid in the cuts and nicks that the knives and cleavers made, and food-borne illness went way up. Now they're using wood again.
So, TL;DR: Use a wood cutting board, and when you're done, pour boiling water over the cutting surface, then sand it down a bit.
