action levels
(1) Regulatory levels recommended by the Environmental Protection Agency
(EPA) for enforcement by the Food and Drug Administration (FDA) and U.S. Department
of Agriculture (USDA) when pesticide residues occur in food or feed commodities
for reasons other than the direct application of the pesticide. As opposed to
"tolerances" which are established for residues occurring as a direct result
of proper usage, action levels are set for inadvertent residues resulting from
previous legal use or accidental contamination. (2) In the Superfund program,
the existence of a contaminant concentration in the environment high enough
to warrant action or trigger a response under the Superfund Amendments and Reauthorization
Act of 1986 and the National Oil and Hazardous Substances Contingency Plan.
The term is also used in other regulatory programs.
