Regulation of Pesticides

Pesticides are tested and approved for use by the Environmental Protection Agency (EPA), which establishes "tolerances," or maximum residue levels, that limit the amount of a given pesticide that can safely remain in or on a food." The Food and Drug Administration (FDA) is then responsible for monitoring pesticide levels on fruits and vegetables, while the Department of Agriculture (USDA) is charged with the task of surveying pesticide residues in meat, eggs and dairy products.
Many believe that the EPA"s methods for testing pesticides are insufficient because they only examine the effects of exposure to pesticides at high doses. Without conducting research concerning long-term exposure to low doses of pesticides, these studies neglect to base safety levels on real-life situations. Moreover, the tests examine the effects of a single chemical, whereas people are typically contaminated with small amounts of hundreds of pesticides at any one time.
The FDA is also criticized for its inadequate monitoring of pesticide levels on fruits and vegetables. The Environmental Working Group reports that the FDA fails to test the majority of produce consumed in the US, and as a result Americans regularly consume food-bearing residues of illegal pesticides that are not approved for use in the US.
