WASHINGTON (Reuters) - Geese force-fed and then slaughtered for their livers may get their final revenge on people who favor the delicacy known as foie gras: It may transmit a little-known disease known as amyloidosis, researchers reported on Monday.Tests on mice suggest the liver, popular in French cuisine which uses it to make pate de foie gras and other dishes, may cause the condition in animals that have a genetic susceptibility to such diseases, Alan Solomon of the University of Tennessee and colleagues reported.
