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
In 2004 and 2005, the American Veterinary Medical Association House of Delegates, the US accrediting body of veterinary medicine, was forwarded resolutions from its Animal Welfare Committee to oppose the production methods for foie gras. After hearing testimony from 13 delegates, the HOD declined to take a position and left a simple statement: "Limited peer-reviewed, scientific information is available dealing with the animal welfare concerns associated with foie gras production, but the observations and practical experience shared by HOD members indicate a minimum of adverse effects on the birds involved."
