Foie gras
In 2012, France produced around 19,000 tonnes of foie gras representing 75% of the world's production in that year. This required the force-feeding of around 38 million ducks and geese. World production in 2015 is estimated as 27,000 tonnes.
Foie gras controversy
"Until new scientific evidence on alternative methods and their welfare aspects is available", the production of foie gras is prohibited by treaty except for "where it is current practice" among 35 countries bound by the Council of Europe's European Convention for the Protection of Animals kept for Farming Purposes.
