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
Most foie gras producers do not consider their methods cruel, insisting that it is a natural process exploiting the animals' natural features. Producers argue that wild ducks and geese naturally ingest large amounts of whole food and gain weight before migration. They claim that geese and ducks do not have a gag reflex in their throats the same way that humans do, and therefore do not appear to find force feeding uncomfortable. Michael Ginor, owner of Hudson Valley Foie Gras, author of "Foie Gras... A Passion," claims his birds come to him to be fed and says this is important because "a stressed or hurt bird won't eat and digest well or produce a foie gras."
