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 January 2009, The National Advertising Division (NAD) of the Council of Better Business Bureau recommended that New Jersey-based foie gras producer D'Artagnan cease advertising claims that their product is made from "enlarged" rather than "diseased" livers, and that the animals were "hand-raised with tender care". D'Artagnan voluntarily modified their advertising to remove the claims which the agency said had not been "adequately substantiated."
