Chlorpyrifos Banned by EPA via Court Order
The US Court of Appeals for the Ninth Circuit issued an order in August 2018 for the Environmental Protection Agency (EPA) to finalize a ban on the insecticide chlorpyrifos, allowing 60 days for the EPA to implement action by discontinuing any approved uses and revoking all approved limits in food. The EPA banned most home use of the insecticide in the US in 2000, and environmental groups filed a petition in 2007 requesting the complete ban of the insecticide due to neurotoxicity concerns in humans.
