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
City of San Diego: On January 8, 2008, the San Diego City Council unanimously passed a resolution that "commends the Animal Protection and Rescue League (APRL) for raising awareness of the cruel practice of force-feeding ducks and geese to produce foie gras, commends the many San Diego restaurants that have stopped selling foie gras before the California statewide ban goes into effect, and encourages San Diegans to avoid supporting this extreme form of animal cruelty." The resolution also cites an independent Zogby poll finding that 85% of San Diegans favor an immediate ban on foie gras.
