UPDATE 2-Appeals court revives California ban on foie gras

(Adds comments, bylines)

Sept 15 (Reuters) - A federal appeals court on Friday revived a California state law banning the sale of foie gras made from force-fed birds.

The 9th U.S. Circuit Court of Appeals said a lower court judge erred in concluding that the law must be struck down because it conflicted with a federal law governing the production of poultry products.

California's law prohibits the sale of duck, geese and other birds that are force-fed to enlarge their livers, resulting in rich flavors that gourmands prize.

The law was passed in 2004 and took effect in 2012, before being deemed void in 2015.

Friday's 3-0 decision by the Pasadena-based appeals court is a victory for animal rights advocates trying to stop force-feeding. Many chefs opposed the California law, saying they like preparing foie gras and their customers want to eat it.

The state law had been challenged by a group of Canadian duck and geese producers, the Association des Eleveurs de Canards et d'Oies du Quebec; Hudson Valley Foie Gras in Ferndale, New York; and Hot's Restaurant Group in Los Angeles.

"They made a mistake," Hudson Valley manager Marcus Henley said in an interview. "This law has always been unconstitutional and incorrect in its basis. We won't be stopping."

The office of California Attorney General Xavier Becerra, which defended the law, did not immediately respond to requests for comment.

In January 2015, U.S. District Judge Stephen Wilson in Los Angeles agreed with opponents of the foie gras ban that the federal Poultry Products Inspection Act preempted it.

But in Friday's decision, Circuit Judge Jacqueline Nguyen said California was simply trying to ban a feeding method it deemed cruel and inhumane.

She said this posed no conflict with the federal law, even if its enforcement resulted in an effective ban on foie gras.

"Nothing in the federal law or its implementing regulations limits a state's ability to regulate the types of poultry that may be sold for human consumption," Nguyen wrote.

Jared Goodman, a lawyer for People for the Ethical Treatment of Animals, said that group was "thrilled" by the decision.

"It prohibits selling diseased livers of birds force-fed by jamming tubes down their throat and pumping concentrated food down their esophagus," Goodman said in an interview. "This is truly torture and unimaginable cruelty." (Reporting by Jonathan Stempel and Richard Leong in New York, and Lisa Baertlein in Los Angeles; Editing by Lisa Von Ahn and Diane Craft)
