Which organization is responsible for regulating pesticide use in the United States?

The Environmental Protection Agency (EPA) is the key organization responsible for regulating pesticide use in the United States. The EPA's role includes evaluating the safety and effectiveness of pesticides before they can be marketed, as well as enforcing regulations to ensure they are used in a manner that minimizes risks to human health and the environment. This involves reviewing the scientific data provided by manufacturers, assessing the potential environmental impact, and establishing guidelines for safe application and handling.

The other organizations mentioned have different primary responsibilities. The Food and Drug Administration (FDA) oversees food safety, including pesticide residues on food products but does not regulate pesticide use directly. The Department of Agriculture (USDA) is involved in agricultural policies including support for farmers, but it is not the primary regulatory body for pesticides. The Occupational Safety and Health Administration (OSHA) focuses on workplace safety and health standards but does not have the authority to regulate pesticides in the same way the EPA does. This context highlights the specific role the EPA plays in ensuring pesticides are used safely and responsibly.
