11. US Pork – European Union
The European Union has banned the import of pork from the United States due to the use of ractopamine, a feed additive that promotes leanness in pigs. Ractopamine is banned in the EU because of concerns about its effects on animal welfare and human health. As a result, American pork products are not found in European supermarkets, and the debate over the safety and ethics of ractopamine continues.
