Why are people suing chlorpyrifos pesticide manufacturers?

A recent study from UCLA Health found that long-term exposure to the insecticide chlorpyrifos (known as Dursban, Lorsban, Cobalt, Lock-On, and many other brands) could make users up to 2.5x more likely to develop Parkinson’s disease.

Researchers have known about the pesticide’s potential health risks since at least 2000, when the U.S. EPA banned Dursban for home use after finding it could cause long-term neurological damage in children. Now, hundreds of agricultural workers and homeowners with Parkinson’s disease have begun filing claims against Dow Agrosciences and other manufacturers for not warning them about these risks.

How to qualify for the lawsuit

Agricultural workers and homeowners diagnosed with Parkinson’s disease, Parkinsonism or Parkinson’s-like symptoms in 2000 or later after using chlorpyrifos insecticides may be eligible for significant financial compensation. Brands named in the lawsuit include, but are not limited to:

Chlorpyrifos Lawsuit FAQs

What if I don’t know which brand I used?

As long as you used a pesticide with chlorpyrifos as the main ingredient, like the brands above, you should be able to qualify if you meet the eligibility conditions. However, if you don’t know which pesticide your brand contains, or your brand contains a DIFFERENT pesticide than chlorpyrifos—like Paraquat or Roundup/glyphosate—then you unfortunately would not qualify.

What if I was only exposed and didn’t use this pesticide myself?

At this time, we can only accept claims for victims who have personally sprayed, mixed, or crop-dusted an insecticide containing chlorpyrifos. If you or a loved one only have a history of second-hand exposure near your home or at your job, your case would unfortunately not qualify.

How much can I expect to win for a settlement?
