Chlorpyrifos has been linked to developmental delays in kids and other health problems. The EPA is fighting a lower court's ruling that it must ban the pesticide, which farmers say they need.
The insecticide chlorpyrifos, already under attack for its risk to small children, may be killing salmon as well. The National Marine Fisheries Service is recommending restrictions on its use.
New EPA administrator Scott Pruitt has decided not to ban chlorpyrifos, a pesticide widely used on produce. That's despite evidence previously compiled by EPA showing it could pose risks to consumers.
