Which three government agencies are responsible for regulating the development, approval, and use of animal health products?

The correct answer identifies the three key agencies involved in regulating animal health products: the Food and Drug Administration (FDA), the Environmental Protection Agency (EPA), and the United States Department of Agriculture (USDA).

The FDA is primarily responsible for approving animal drugs, ensuring their safety and efficacy for both animals and humans. This agency oversees pharmaceuticals, biologics, and food additives used in animal health. The EPA is responsible for regulating products that may have environmental impacts, including pesticides and certain veterinary drugs that can affect the ecosystem. The USDA plays a crucial role in animal health through its oversight of veterinary biologics and livestock health programs.

In contrast, other combinations of agencies provided in the options, such as those involving the Department of Health and Human Services (HHS), the National Institutes of Health (NIH), the Centers for Disease Control and Prevention (CDC), and the National Institute for Occupational Safety and Health (NIOSH), do not have direct regulatory authority over animal health products in the same comprehensive manner as the FDA, EPA, and USDA. Each of those organizations has important functions in public health and related fields, but they do not collectively manage the approval and regulation of animal drugs and health products the way the three mentioned agencies do.
