What does the USDA primarily regulate?

The USDA primarily regulates meat, poultry, and eggs across state lines due to its role in ensuring food safety, quality, and proper labeling. This federal oversight is essential because contaminants and unsafe practices can cause widespread issues beyond local borders. By overseeing these products, the USDA helps to maintain consistent standards throughout the country, promoting public health and consumer trust in the food supply.

The role of the USDA is particularly crucial in the case of meat and poultry, as these products can carry higher risks of foodborne illnesses if not processed and handled correctly. The regulation extends to facilities that process these items, ensuring they meet federal guidelines designed to protect consumers.

In contrast, the other options focus on products or inspections that do not fall under the primary jurisdiction of the USDA. For instance, while canned foods and beverages are important food items, their regulation is primarily the responsibility of the FDA, which oversees the safety and labeling of processed foods. Similarly, dairy and grains, typically regulated at the state level, do not involve interstate commerce in the same way that meat, poultry, and eggs do. Grocery store inspections, while vital for public health, are generally managed by local health departments, which enforce state-level regulations rather than federal guidelines.
