The federal Poultry and Poultry Products Inspection Act (21 U.S.C. §§ 451 et seq.) expressly preempts state laws that impose different or additional labeling requirements to the labels approved by the Secretary of Agriculture under the PPIA. (21 U.S.C. 467e.) This decision holds that the federal statute preempts any state law claim that the federally approved label for a poultry product–here, a label showing the product was certified by the American Humane Association as being humanely raised. Since the Secretary had approved the label showing the certification as not misleading, the plaintiff could not state a claim under state law based on the assertion that the American Humane Association certification was a sham and the poultry were, in fact, not humanely treated.
