What is the main function of pesticide tolerances established by the EPA?

The primary function of pesticide tolerances established by the Environmental Protection Agency (EPA) is to limit the amount of pesticide residues that can legally remain on food products. This regulation is crucial for ensuring food safety, as it helps protect consumers from potentially harmful levels of chemicals. Tolerances are set based on extensive scientific assessments, which consider the likelihood of exposure and the potential health risks associated with specific pesticide residues. By establishing these limits, the EPA aims to ensure that food supplies are safe for consumption and that agricultural practices remain sustainable while protecting public health.
