Foie gras has been described as "torture in a tin" by animal rights activists because the paté is produced by cruelly force-feeding corn-mash into ducks or geese until their livers swell and burst.
Foie gras is the French for "fat liver", and France is the main producer of foie gras and its production is banned in the UK.
Justin Kerswell of animal rights campaign group Viva! (Vegetarians International Voice for Animals) is reported to have said: "We are very pleased, but foie gras should have been banned a long time ago."
And he added: "Foie gras is seen as very posh and the heir to the throne is probably the poshest person in Britain, so for him to ban it is very good news."
The force-feeding of the ducks and geese is done by inserting a tube down their throats and this often injures the birds and is done 12-18 days before they are killed.
It is said that the practice dates as far back as 2500 BC, when the ancient Egyptians began farming birds for food.
France is the main producer and consumer of foie gras, though it is produced and eaten worldwide, especially in other European nations, America, and China.
