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
In late 2015, there were several outbreaks of the highly contagious H5N1 bird flu in France, which escalated during 2016. This led to Algeria, China, Egypt, Japan, Morocco, South Korea, Thailand and Tunisia banning French poultry exports, including foie gras, and France to initiate increased bio-security protocols which will cost an estimated 220 million euros. One of these measures was the halting of production in southwestern France from early April, 2016 for an anticipated period of three months to reduce the spread of the virus. Exports of foie gras from France are expected to decrease from 4,560 tonnes in 2015 to 3,160 tonnes in 2016.
