Which organization regulates food safety on a national level in the United States?

The Food and Drug Administration (FDA) plays a crucial role in regulating food safety on a national level in the United States. The FDA is responsible for overseeing the safety and labeling of most food products, including packaged foods, seafood, dietary supplements, and bottled water. The agency ensures that food is safe and sanitary, preventing adulteration and misbranding, and it establishes guidelines for safe food handling and preparation.

In addition to its regulatory responsibilities, the FDA also conducts research and develops food safety policies to address emerging issues in the food supply, such as foodborne illnesses. This comprehensive approach helps protect public health and ensures that food consumers can trust the products they purchase.

While other organizations like the USDA, EPA, and CDC are involved in different aspects of food safety, such as inspecting meat and poultry, environmental protection, or tracking foodborne illnesses, the primary regulatory authority concerning a wide array of food products falls under the jurisdiction of the FDA. This makes it the correct answer for the question regarding national food safety regulation in the United States.
