What is the primary function of the FDA?

The primary function of the FDA, or Food and Drug Administration, is to ensure the safety and effectiveness of food, drugs, and other consumer products. Specifically, the FDA is tasked with overseeing the safety of all foods, excluding those regulated by the USDA, which include meat, poultry, and seafood. This division of responsibilities is important because it allows for specialized oversight and regulation tailored to the unique aspects of different food categories.

The FDA plays a vital role in the public health by establishing and enforcing regulations that prevent foodborne illnesses and ensure that food products meet safety standards before they reach consumers. By focusing on food safety, the FDA also works to protect public health from potential hazards associated with food consumption.

While other options mention important functions, they do not encapsulate the FDA's primary role as effectively. Regulating health services in hospitals and overseeing consumer products are typically under the purview of other agencies. Managing the distribution of drugs is a part of the FDA's responsibilities, but it is a narrower focus within the broader context of ensuring food safety across more than just drugs. Hence, the correct answer highlights the FDA's commitment to food safety specifically, underscoring its critical role in public health.
