Service (FWS). CSRS has its own programs through land-grant universities. All these agencies have some analytical capability associated with pesticide monitoring in foods (FDA, FSIS) or pesticide research.

Following is a list of the principal responsibilities of each agency:

The Environmental Protection Agency

• registers pesticides under FIFRA;

• sets pesticide tolerance concentrations for individual commodities, including meat and poultry, and for processed foods (the tolerance concentration for individual commodities is established by EPA for raw produce at the farm gate; as produce is processed into finished foods, pesticide concentrations may either decrease, increase, or remain the same);

• serves as lead agency for enforcement;

• reviews manufacturers' registration data, including analytical methods; and

• conducts research on the environmental fate of residues.

The Food and Drug Administration

• enforces compliance with residue tolerance concentrations in food, except meat and poultry, and feed;

• monitors residues in domestic and imported food; and

• develops analytical methods for monitoring.

The Food Safety and Inspection Service (USDA)

• enforces residue tolerance concentrations in meat and poultry;

• monitors residues in meat and poultry;

• develops analytical methods for monitoring; and

• gathers information on the incidence and concentrations of pesticide residues in the food supply.

The Agricultural Marketing Service (USDA)

• enforces compliance with residue tolerance concentrations and monitors residues in raw egg products.

The Agricultural Research Service (USDA)

• conducts research on pesticides, including efficacy and residue fate, and

• conducts ARS segment of IR-4 and National Agricultural Pesticide Impact Assessment Program (NAPIAP) operations.

The Cooperative State Research Service (USDA)

• oversees and funds NAPIAP and IR-4, both of which operate at land-grant universities.

The Fish and Wildlife Service

• monitors pesticides in fish and wildlife.
