Foie Gras

Foie gras is the French term for “fat liver” and it refers to a food product made from the liver of a specially fattened goose or duck. According to French law, force feeding a duck or goose is necessary to produce a high quality foie gras grade liver. The force feeding induces the liver to convert extra food into fat which is stuffed underneath the duck’s skin and inside the liver itself. Eventually, the liver becomes soft and white and the duck is slaughtered only for the liver. The force feeding also produces a nutty, buttery texture in the liver which is quite unlike any other meat or sweetbread.


Force feeding birds to produce a fatter, softer textured bird was a technique first invented by the Egyptians in 2498 BC to 2345 B.C. Bas relief in the ancient city of Saqqara are sown in Goose was a prized dish in Egypt and this process was primarily invented to produce a rich, fatty bird for roasting or cooking. The Egyptians also presented fatted birds as gifts to visiting royalty like Agesilaus, King of Sparta. By the late second century, this process of fattening the bird had spread over to Rome and the Romans first noticed that the force feeding procedure produced a fat liver which was delicious in taste and texture. There are several recorded mentions of the dish in Roman literature with Greek poet Cratinus, Roman statesman Cato the Elder and Julius Pollux, a Greek rhetorician; all mentioning the process and the liver in their writings. This process of creating the fattened birds and their livers was carried out by Jewish slaves in the Roman territories. The process then spread over to Jewish aristocracy in Palestine and became very popular in the Mediterranean. Jews who had migrated to France and Germany carried the technique with them to these countries too.

How is Foie Gras Produced?

Traditionally, the ancient Egyptians held the duck neck between their knees which forcing soaked wheat down their gullets. The Romans used the same technique but they preferred to use figs and honey. It is also stated that the duck’s feet were nailed down to the floor to prevent them from exercising as exercise would cause the fat in the body and liver to automatically reduce. Nowadays, the goslings or ducklings are kept in straw for the first four weeks. They are then fed on grasses for a few weeks. Only males are force fed corn for a period of 12-18 days. The ducks are fed twice daily while geese are fed up to five times daily. In a few areas, the force feeding is still done manually but special machines are also available to carry out the process.

Over the last few years, there has been a lot of controversy over the force feeding of ducks. Several countries have banned the force feeding or gavage procedure as it is considered to be cruel and injurious to the duck. Animal rights activists like PETA, Vival and Humane Society Of the United States contend that the process is inhumane and can make it difficult for the bird to breath.
