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.) Defendant bears the burden of proving federal preemption and thus, when the issue is contested, must prove that the Secretary of Agriculture reviewed and approved its label for its chicken products. If so approved, the label cannot be assailed on state law grounds. To the extent defendant’s website merely repeated the statements on the product label, it is also immune from attack under state law if the Secretary of Agriculture approved the label. However, insofar as the website went beyond the label, it is subject to state law claims whether or not the label was approved.
