Chicago is the first U.S. city to ban the sale of foie gras, the fatty liver of ducks and geese produced by force feeding and usually served as a paté. Passed 48-1 vote by the Chicago City Council, the measure takes effect in 90 days, with fines of up to $500/day.

California earlier enacted a similar ban but it won't become effective until 2012. Other states considering such laws include Illinois, Hawaii, Massachusetts, New York and Oregon, Meatnews.com reports.

Meanwhile, the NY Times reports a group of growers on Monday formed the North American Foie Gras Producers Association. It plans to hire a public advocacy and lobbying group to examine the constitutionality of such laws. Only New York and California have significant foie gras operations, the article says.

"If force-feeding a duck is cruel, then packing chickens in a cage is cruel, and then the veal and the beef. We are all going to be vegetarians soon if they have their way," French restaurant owner Thomas Keller told the NY Times. -- Joe Roybal
