On February 25, 2022, the U.S. EPA rejected all comments opposing the removal of the current maximum residue limits for Chlorpyrifos in food, a move that signals a complete ban on all Chlorpyrifos-related food purposes by EPA.

In addition, EPA has sent letters to registrants of Chlorpyrifos products with food purposes, and registrants have the option of removing food-related purposes from product labels or voluntarily canceling products with food purposes only. For food purposes that are not removed and for food-only products that are not voluntarily cancelled, EPA will subsequently issue a notice for mandatory removal of food purposes or cancellation of registration.

Chlorpyrifos is an organophosphorus insecticide used on crops including soybeans, fruit and nut trees, broccoli, and cauliflower.

However, because Chlorpyrifos inhibits acetylcholinesterase (AChE) in the body, leading to neurotoxicity, Chlorpyrifos use has been declining, and many other countries, including the European Union and Canada, and some states, including California, Hawaii, and New York, have taken action to restrict the use of Chlorpyrifos in food, so it has undergone several reviews since its registration in 1965.

The following is a review of EPA's regulatory record:

In 2000, to resolve the health and environmental risks associated with Chlorpyrifos exposure, Chlorpyrifos registrants voluntarily entered into agreements with EPA to eliminate, and modify, certain purposes;

In 2002, EPA made changes to required safety measures to ensure environmental and worker safety;

In 2011, EPA completed a comprehensive preliminary of human health risk assessment for all purposes of Chlorpyrifos;

In 2012, EPA adopted mitigative decisions for Chlorpyrifos spray drift, significantly reducing aerial pesticide use and creating "no-spray" buffer zones;

In 2014, EPA revised the human health risk assessment to consider exposures from multiple sources, incorporating information from the 2012 spray drift exposure assessment and new restrictions implemented to limit spray drift;

In 2016, EPA revises again the human health risk assessment and retains the safety factor (10×FQPA);

In 2020, the draft ecological risk assessment, and the third revised human health risk assessment;

In 2021, the final tolerance rule for Chlorpyrifos, which withdraws all residue limits for Chlorpyrifos and plans to cancel with the withdrawal of its food purposes.
