(AP) - California is trying to keep foie gras off the menu.
The attorney general's office filed an appeal Wednesday of a ruling that blocked the state ban on selling fatty goose or duck liver produced out of state.
A federal judge ruled last month that the law doesn't trump federal poultry regulations.
A Hermosa Beach restaurant called Hot's Kitchen and foie gras producers in New York and Canada challenged the ban.
It remains illegal for California farmers to force-feed birds, which is how the delicacy is produced. Animal rights groups say the practice is inhumane.
A statement from the restaurant and producers say they're confident the ban will be upheld on appeal.
