Pesticide residue

Pesticide residue refers to the pesticides that may remain on or in food after they are applied to food crops. The maximum allowable levels of these residues in foods are often stipulated by regulatory bodies in many countries. Exposure to these residues most commonly occurs through consumption of treated food sources, skin contact, or inhalation.

Pesticide residues can be found in the environment, including soil, water, and air. They can also be present in non-target organisms. The amount of pesticide residue that remains in or on food is determined by the residue definition.

Regulation

In the United States, the Environmental Protection Agency (EPA) establishes the maximum levels of pesticide residues that can be present in food. These levels are called tolerances in the U.S. and Maximum Residue Limits (MRLs) in many other countries.

In the European Union, the European Food Safety Authority (EFSA) is responsible for evaluating the possible risks of pesticide residues in food and setting MRLs.

Health effects

Exposure to pesticide residues can lead to a variety of health effects, depending on the specific pesticide and the amount of exposure. These can include neurological effects, cancer, and endocrine disruption.

Detection

Various methods are used to detect pesticide residues in food, including chromatography, mass spectrometry, and bioassay.
