Chlorpyrifos — a toxic pesticide used heavily on American farms and orchards for decades — has been linked to Parkinson's disease in agricultural workers and serious brain and developmental injuries in children exposed before birth or in early childhood. Despite mounting scientific evidence and an eventual EPA ban for food use in 2021, the chemical was sprayed across millions of acres for years. Manufacturers including Corteva (formerly Dow) and others are now facing lawsuits alleging they knew about these neurological risks and failed to warn workers, families, and communities. If chlorpyrifos exposure has harmed you, your spouse, or your child, you may have legal options to pursue compensation.
Manufacturers are facing a wave of civil lawsuits brought by farmworkers, families, and communities who say they were never warned about the neurological dangers of chlorpyrifos.
Chlorpyrifos lawsuits target manufacturers including Corteva (formerly Dow AgroSciences), Drexel Chemical, and other producers of the organophosphate pesticide marketed under brand names like Lorsban and Dursban. Plaintiffs allege the manufacturers knew for decades that chlorpyrifos crosses the blood-brain barrier and damages the nervous system — yet continued selling it widely for use on crops, in orchards, and in homes.
The first group of plaintiffs are agricultural workers and applicators who developed Parkinson's disease after years of chronic occupational exposure. Peer-reviewed studies have linked chlorpyrifos exposure to a significantly elevated Parkinson's risk. For farmworkers, pesticide applicators, and others who handled or worked around the chemical season after season, the cumulative toll on the nervous system can be severe.
The second group are families whose children suffered developmental disorders, brain damage, autism spectrum diagnoses, IQ deficits, ADHD, or other neurological injuries linked to prenatal or early-childhood exposure — often near farms, fields, or in agricultural communities where chlorpyrifos was sprayed. The EPA banned chlorpyrifos for food use in 2021 after years of regulatory delay, but for many families and workers, the damage was already done.
