What is the Paraquat Herbicide – Parkinson’s Lawsuit About?
Paraquat is a powerful herbicide often used by farmers, landscapers, and agricultural workers to control weeds and grasses. However, scientific studies have shown that long-term exposure to Paraquat may dramatically increase the risk of developing Parkinson’s disease, a progressive neurological disorder that affects movement, speech, and overall quality of life.
Despite these health risks, manufacturers allegedly failed to provide proper warnings on the product labels or inform users of the long-term dangers. People who spent years working with Paraquat—without any protective warnings—are now facing devastating diagnoses and life-altering challenges.
As awareness has grown, thousands of individuals have joined the fight, filing lawsuits to hold these companies accountable for the harm caused by toxic Paraquat exposure.
The number of individual lawsuits filed in various federal and state courts across the country begins to increase significantly as awareness grows. Attorneys for the plaintiffs argue that the cases involve common questions of fact, laying the groundwork for consolidation.
June 2021:
The U.S. Judicial Panel on Multidistrict Litigation (JPML) officially consolidates the growing number of federal Paraquat lawsuits into a Multidistrict Litigation (MDL). The MDL is assigned to the Southern District of Illinois under Chief Judge Nancy J. Rosenstengel. This move streamlines the legal process for thousands of similar claims by centralizing pretrial proceedings like discovery and expert testimony.
2022-2023:
The number of plaintiffs in the MDL rapidly expands from a few hundred to several thousand. During this period, legal teams focus on the discovery process, gathering evidence, and deposing witnesses. The court schedules the first "bellwether" trials—test cases intended to help both sides gauge jury reactions and determine potential settlement values—but these initial trial dates are postponed.
2025
he litigation remains active and is considered a developing case. The number of filed claims continues to climb as new plaintiffs join the MDL. The legal focus is on expert witness challenges (Daubert hearings) and preparing for the first bellwether trials, which are now anticipated in the near future.

2. Is there a deadline to file?

5. Who are the companies being sued?
Major defendants include Syngenta, Chevron, and Growmark, all of which have manufactured or distributed Paraquat.
