On August 9, 2018, the U.S. Court of Appeals for the Ninth Circuit ruled that EPA revoke all tolerances and cancel all registrations for chlorpyrifos within 60 days. The court found “There was no justification for the EPA’s decision in its 2017 order to maintain a tolerance for chlorpyrifos in the face of scientific evidence that its residue on food causes neurodevelopmental damage to children.”
Why it Matters
Chlorpyrifos is a highly toxic organophosphate pesticide used since 1965 on food and oil crops, and cotton – and on golf courses. It is the most widely used conventional pesticide in the United States. Over time, the Environmental Protection Agency (EPA) has narrowed the acceptable uses for this pesticide, as research revealed serious health and ecological risks. For instance, in 2000, the EPA banned the use of chlorpyrifos for household use (except for child-resistant ant and roach traps) and on tomatoes.
