Anyone who's concerned about salmonella, hormone levels or animal welfare, can just not buy any products that could potentially contain animal products from countries with weak animal welfare or sanitary laws. The rest is just making life of farmers/shops/wholesalers harder.

Especially with these European intentions, I frankly believe that one single country's laws should be universal and no other country may implement or enforce laws that protect their consumers. The onus to protect themselves from harm must lie with the individuals and governments should not dare inconvenience anyone just to protect their citizens' interests.
