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.
Foie gras controversy
Late in 2003, the French group Stopgavage ("Citizens' Initiative for the banning of force-feeding") published the Proclamation for the Abolition of Force Feeding, which asks justices to find foie gras production practices a violation of existing animal welfare laws. For this manifesto Stopgavage claims the support of over eighty French animal rights and welfare associations, over a hundred such associations from 25 other countries, and over 20 thousand individual signatories.
