If you were diagnosed with Parkinson's disease after years living, working, or attending school near fields treated with the pesticide chlorpyrifos, you may qualify for compensation.
Chlorpyrifos is an organophosphate pesticide that was widely used on U.S. farmland for decades, including on crops grown near homes, schools, and worksites. Lawsuits filed against manufacturers including Corteva, Dow, and FMC allege the companies knew or should have known that long-term exposure to chlorpyrifos was linked to neurological harm, including Parkinson's disease, and failed to adequately warn people who lived, worked, or went to school near treated fields.
A 2026 study found that people with significant long-term residential exposure to chlorpyrifos had a substantially higher risk of developing Parkinson's disease compared to those without that exposure. Plaintiffs allege the companies had access to data pointing to this risk well before it became public.

Individual lawsuits over chlorpyrifos and Parkinson's disease are a new and actively developing area of litigation, with cases including Ramos v. Corteva, Inc. now pending in the U.S. District Court for the Eastern District of Pennsylvania, and a group of claims filed in Delaware Superior Court in September 2026 naming Corteva, Dow, and Loveland Products. These cases have not been consolidated into a formal multidistrict litigation, no trial dates have been set, and causation remains a contested, developing legal question — which is exactly why an individual eligibility review, rather than a general news story, is the fastest way to find out where a specific claim stands.
Four men from Pennsylvania, North Dakota, Connecticut and Delaware filed suit in Delaware Superior Court on September 15, 2026, alleging that years of exposure to the insecticide chlorpyrifos caused their Parkinson's disease. It is one of only a handful of chlorpyrifos Parkinson's cases filed so far.
