Poultry
In some countries, geese and ducks are force-fed to produce livers with an exceptionally high fat content for the production of "foie gras". Over 75% of world production of this product occurs in France, with lesser industries in Hungary and Bulgaria and a growing production in China. "Foie gras" is considered a luxury in many parts of the world, but the process of feeding the birds in this way is banned in many countries on animal welfare grounds.
American Veterinary Medical Association
The AVMA has voted on several proposals to take a formal stand against the forced feeding of birds to make foie gras. Although foie gras has been banned in many countries in Europe, as well as in the U.S. state of California, because of an absence of science specifically addressing the welfare aspects of foie gras production, as well as conflicting opinions among its membership, the AVMA opted not to take a stand either for or against foie gras. The AVMA has published a welfare implications of foie gras production backgrounder.
