What organization is responsible for enforcing the tolerances that are set for a pesticide on food?

The Environmental Protection Agency (EPA) is responsible for enforcing the tolerances set for pesticides on food in the United States. These tolerances define the maximum allowable levels of pesticide residues that can be present on food products. The EPA establishes these limits based on safety assessments and scientific data to ensure that pesticides do not pose a risk to human health or the environment. Additionally, the Food and Drug Administration (FDA) and the United States Department of Agriculture (USDA) also play roles in monitoring and regulating pesticide residues in food.
