EPA Denies Objections to Rule Revoking All Chlorpyrifos Tolerances on Food

The U.S. Environmental Protection Agency (EPA) is taking the next step to discontinue use of the pesticide chlorpyrifos on food by denying objections to EPA’s rule revoking all chlorpyrifos tolerances. Previously, chlorpyrifos was used for a large variety of agricultural uses, including soybeans, fruit and nut trees, broccoli, cauliflower, and other row crops. It has been found to inhibit an enzyme, which leads to neurotoxicity, and has also been associated with potential neurodevelopmental effects in children. A final rule revoking all chlorpyrifos tolerances on food was issued in August 2021, and after a period to file objections, EPA is denying all objections, hearing requests, and requests to stay the final rule. After considering public comments, EPA will proceed with registration review for the remaining non-food uses, which may propose additional measures to reduce human health and ecological risks.
