Foie gras
In 2016, it was reported that France produces an estimated 75% of the world's foie gras and southwestern France produces approximately 70% of that total. In 2016, it can retail for upwards of $65 a pound.
Foie gras
Fattened liver can be produced by alternative methods without gavage, and this is often referred to either as "fatty goose liver" or as foie gras (outside France), though it does not conform to the French legal definition. This method involves timing the slaughter to coincide with the winter migration, when livers are naturally fattened.
The winner of the Coup de Coeur award at the Salon International d'Alimentation, SIAL 2006, Patería de Sousa produces fattened livers without force-feeding. This has only recently been produced commercially, and is a very small fraction of the market.
