The paraquat Parkinson's lawsuit.
Research has examined whether long-term exposure to paraquat, a widely used herbicide sold under brand names such as Gramoxone, is linked to Parkinson's disease. Thousands of cases are now consolidated in federal court. If you or a loved one were affected, you may be able to request a case review.

What the paraquat lawsuit is about.
A body of research has examined whether long-term exposure to paraquat is associated with an increased risk of Parkinson's disease. Plaintiffs in the paraquat litigation allege that the manufacturers, including Syngenta and Chevron, knew or should have known about this potential risk and failed to adequately warn the workers who handled the herbicide.
The federal cases have been consolidated as multidistrict litigation (MDL 3004) in the U.S. District Court for the Southern District of Illinois, before Chief Judge Nancy Rosenstengel. An MDL is not a class action: each plaintiff retains an individual case, but pretrial proceedings are coordinated before a single judge for efficiency.
Situations that often fit the claim pattern.
Eligibility for a paraquat claim depends on the exposure history, the timing of diagnosis, and the laws of your state. The following situations are the ones most often reviewed:
- Worked with paraquat or Gramoxone as a farmer, applicator, mixer, loader, or crop duster and later diagnosed with Parkinson's disease
- Repeated agricultural or occupational exposure over multiple seasons or years before a Parkinson's diagnosis
- Lived or worked near treated fields and exposed to drift from paraquat spraying
- Diagnosed with Parkinson's disease years after the exposure period, which is common given the long latency
- A loved one was diagnosed with Parkinson's disease after years of working around paraquat
Damages that may be recovered.
The value of any individual claim depends on the severity of the injury, the exposure history, and the laws of your state. No outcome is guaranteed. Speak with a licensed attorney as soon as possible, since statutes of limitations vary and may be short.

Paraquat lawsuit FAQ.
What is the paraquat lawsuit about?
The paraquat lawsuit centers on allegations that the makers of paraquat, including Syngenta and Chevron, failed to warn workers that long-term exposure to the herbicide is linked to Parkinson's disease. The federal cases are consolidated as multidistrict litigation (MDL 3004) in the Southern District of Illinois before Chief Judge Nancy Rosenstengel.
Who may qualify for a paraquat lawsuit?
Generally, people who had long-term exposure to paraquat, often through farm work, mixing, loading, or spraying, and were later diagnosed with Parkinson's disease may potentially qualify. Eligibility depends on the exposure history, timing of diagnosis, and the laws of the state where the claim is filed.
How do I file a paraquat lawsuit, and how long do I have?
Statutes of limitations vary by state and generally run from the date of diagnosis or the date the illness was reasonably connected to paraquat. Because of the long gap between exposure and a Parkinson's diagnosis, many people are still within their filing window, but deadlines can be short. The usual first step is to speak with a licensed attorney, who can file an individual case, often directly into MDL 3004.
Is the paraquat lawsuit a class action or an MDL?
The federal paraquat cases are consolidated as a multidistrict litigation (MDL 3004) in the Southern District of Illinois. An MDL is not the same as a class action. Each plaintiff keeps an individual case, but pretrial proceedings are coordinated before a single judge for efficiency.
What compensation may be available in a paraquat lawsuit?
Damages may include past and future medical expenses, lost wages and reduced earning capacity, pain and suffering, and loss of consortium. As of 2026 no global paraquat settlement has been announced, and amounts depend on the specific facts of each case. No outcome is guaranteed.
What if I'm not sure which paraquat product I used?
Many people do not recall the exact product or every year of exposure. An attorney can help reconstruct a work and exposure history using employment, application, and product records. You can submit a case review request with approximate dates and details.
