The US Environmental Protection Agency (EPA) has announced the revocation of most food applications for the pesticide chlorpyrifos, following a US Court of Appeals for the Eighth Circuit ruling. The regulation exempts 11 registered crops, including alfalfa, apples, and asparagus. This new rule is projected to cut US annual chlorpyrifos use by 70%, a significant reduction from historical levels. The exempt crops are:
- Alfalfa
- Apples
- Asparagus
- Tart cherries
- Citrus
- Cotton
- Peaches
- Soybeans
- Strawberries
- Sugar Beets
- Wheat (spring and winter varieties)
Chlorpyrifos, an organophosphate pesticide, was widely used in crops like soybeans, fruit trees, and vegetables, as well as for non-food purposes. Long-term, high-dose exposure can cause neurological disorders, such as tremors, fatigue, and nausea, and may affect the neurodevelopment of pregnant women and children.
Ban History Overview
The EPA previously banned chlorpyrifos to remove it from food and animal feed but was overturned three months later. In February, following court instructions, the EPA reset limits on chlorpyrifos use, aligning with the court's ruling and the 11 uses identified in the 2020 interim registration review decision. These applications are expected to reduce historical annual usage by 70%.
Next Steps
The EPA is committed to protecting public health, especially that of infants and children, by reducing chlorpyrifos levels in food. A revised draft policy on chlorpyrifos is planned for 2026, aiming to minimize health and environmental risks associated with pesticide exposure.
