Which regulatory body is primarily responsible for enforcing HACCP guidelines in the United States?

The Food and Drug Administration (FDA) is primarily responsible for enforcing HACCP guidelines in the United States, particularly for seafood and juice products, as well as for the overall regulation of food safety. The FDA’s implementation of HACCP focuses on preventing food safety hazards through a systematic approach of identifying critical control points in food production and processing.

While the USDA supervises meat, poultry, and egg products and also utilizes HACCP principles in their inspection processes, the FDA's role encompasses a broader range of food products. The EPA primarily manages environmental regulations, and OSHA focuses on workplace safety and health rather than food safety practices. Thus, the FDA stands out as the correct regulatory body enforcing HACCP guidelines in the context provided.
