Which federal agency is responsible for regulating meat, poultry, and processed egg products?

The United States Department of Agriculture (USDA) is the federal agency responsible for regulating meat, poultry, and processed egg products. This responsibility includes ensuring that these products are safe, wholesome, and accurately labeled. The USDA establishes standards for the inspection and grading of these food products and oversees the entire production process, from the farm to the table.

The USDA's Food Safety and Inspection Service (FSIS) specifically handles the inspection and regulation of meat and poultry processing facilities, setting guidelines to prevent contamination and ensure food safety. This role is crucial for maintaining public health as it helps to prevent foodborne illnesses associated with these types of products.

In contrast, the Food and Drug Administration (FDA) oversees a broader range of food products, mainly those not covered by USDA, which includes fruits, vegetables, seafood, and packaged foods. The Centers for Disease Control and Prevention (CDC) focuses on monitoring and preventing disease outbreaks rather than directly regulating food products. The Environmental Protection Agency (EPA) deals with environmental protection and regulation, such as pesticides and contaminants, rather than food product regulation. Thus, the USDA's dedicated role in the inspection and regulation of meat, poultry, and processed egg products makes it the correct answer.
