Foie gras
The technique of gavage dates as far back as 2500 BC, when the ancient Egyptians began keeping birds for food and deliberately fattened the birds through force-feeding. Today, France is by far the largest producer and consumer of foie gras, though it is produced and consumed worldwide, particularly in other European nations, the United States, and China.
Foie gras controversy
The report of the European Union's Scientific Committee on Animal Health and Animal Welfare on Welfare Aspects of the Production of Foie Gras in Ducks and Geese, adopted on December 16, 1998, is an 89-page review of studies from several producing countries. It examines several indicators of animal welfare, including physiological indicators, liver pathology, and mortality rate. It strongly concludes that "force feeding, as currently practised, is detrimental to the welfare of the birds."
