Diazinon is a dangerous organophosphate pesticide that poisons farmworkers, children, bystanders, fish, birds, and wildlife. EPA found health risks for diazinon, yet approved its continued use without requiring mitigation to reduce those risks and without ensuring that there are no unreasonable adverse effects, as required by federal pesticide law. This is especially true for impacts to children and agricultural communities from drift and run-off. EPA also failed to initiate or complete consultation on the impacts of diazinon to threatened and endangered species. 

Earthjustice has filed suit to compel EPA to follow the law and reassess the threats this pesticide poses to the public and the environment.
