Animals' and birds' livers are often eaten as food, including [[lamb]], [[chicken]], [[duck]] and [[goose]] liver. Liver [[pâté]], such as [[foie gras]] is considered a delicacy, although there are concerns over the treatment of the ducks or geese involved, since this pâté can only be produced by chronically overfeeding them to engorge the liver. | Animals' and birds' livers are often eaten as food, including [[lamb]], [[chicken]], [[duck]] and [[goose]] liver.
