Final answer:
The U.S. Department of Agriculture (USDA) is responsible for administering and regulating the National Organic Program (NOP), which sets the standards for organic agriculture.
Step-by-step explanation:
The federal department responsible for administering and regulating the National Organic Program (NOP) is the U.S. Department of Agriculture (USDA). The USDA sets the standards for organic agriculture, including prohibiting the use of most synthetic pesticides and fertilizers on organic crops, and outlining how organic animal products must be produced.
While the FDA is responsible for food safety and consumer protection in many aspects, the NOP, which assures that organic food products are produced according to federal guidelines, is under the umbrella of the USDA, not the FDA. It's also important to note that the Food Safety Alliance for Packaging (FSAP) and Center for Food Safety and Applied Nutrition (CFSAN) are related to food safety but do not regulate organic agriculture, which is distinctly under the USDA's domain.
