Chlorpyrifos Pesticide Lawsuit

Exposure to the dangerous pesticide chlorpyrifos is associated with neurological harm in children. If you and/or your unborn child were exposed to this dangerous chemical, compensation may be available.


What is Chlorpyrifos?

Chlorpyrifos is an insecticide that was widely used to control many types of pests since 1965 when it was first registered with the US Environmental Protection Agency (EPA). The pesticide was commonly applied to crops including soybeans, fruit and nut trees, broccoli, cauliflower, and other row crops, as well as for non-food use.

Studies have shown chlorpyrifos is associated with potential neurological effects in children. The pesticide inhibits an enzyme that leads to neurotoxicity, damage to the brain or peripheral nervous system. Exposure to the pesticide has health risks, whether through touch, inhaled, or eaten. Corteva Agriscience, a major manufacturer of chlorpyrifos, ceased production of products containing the chemical in 2021.

Health Risks during Pregnancy and Childhood

Children are particularly vulnerable to the health risks of pesticides, including in-utero or during pregnancy. Exposure to chlorpyrifos products, including Lorsban, Vulcan, Dursban, and Warhawk, include:

  • ADHD
  • Autism
  • Brain damage
  • Down’s syndrome
  • Seizure disorders
  • Neurodevelopmental injuries
  • Developmental issues, including low birth weight and reduced IQ

Impact on Children

Research studies tracked the blood of women exposed to chlorpyrifos and the blood of their children from birth to three years.

Children with chlorpyrifos in their blood showed more developmental delays and disorders, as well as attention deficit and hyperactivity disorders.


In August 2021, the US Environmental Protection Agency (EPA) announced it would publish a regulation to block the use of chlorpyrifos on food because of the link to neurological damage in children. In April 2021, the Ninth Circuit Court of Appeals directed the agency to cease agricultural use of the chemical within 90 days, noting that science has linked chlorpyrifos to brain damage for over a decade.

“Today, EPA is taking an overdue step to protect public health. Ending the use of chlorpyrifos on food will help ensure children, farmworkers, and all people are protected from the potentially dangerous consequences of this pesticide.”
— EPA Head Michael S. Regan
