I allows horrendous poultry farming practices, which in the US are "fine" because the meat gets washed afterwards anyway, so who cares chickens are standing in their shit until their own feet dissolve - the end product is fine, right?
I'm not a vegetarian, but god I hope the American chicken never enters this market.
In Europe we believe it's indirectly harmful: Being able to wash germs off meat and eggs allows tolerating more diseases in the farms. If you can't just sanitize diseases off products, you have to keep the farms clean of diseases.
