What Studies Say About Paraquat and Parkinson’s Disease

Paraquat, a commercial herbicide, has been at the center of numerous lawsuits. The reason? Its alleged link to Parkinson’s disease. Let’s dive into what studies and ongoing Paraquat lawsuits reveal about this connection.

The Science Behind the Claims

Studies suggest that Paraquat exposure can lead to oxidative stress, killing dopamine-producing neurons in the brain. This is crucial because Parkinson’s disease is characterized by the death of these neurons. A meta-analysis of multiple studies concluded that pesticide exposure, including Paraquat, increases the risk of developing Parkinson’s by over 50%.

The Legal Angle: Paraquat Lawsuits

Paraquat lawsuits claim that manufacturers failed to warn users about the risk of developing Parkinson’s disease. As of August 2023, there are 4,554 Paraquat lawsuits pending in Illinois federal court. The first bellwether trial has been moved to October 2023. These lawsuits aim to hold companies accountable and seek compensation for the victims.

Who Can File a Lawsuit?

If you’ve been exposed to Paraquat and later developed Parkinson’s, you may qualify for a Paraquat lawsuit. Most people exposed work in commercial agriculture or live near such farms. The lawsuits are not just about compensation; they’re also about spreading awareness of the risks associated with Paraquat.

Is Paraquat Banned?

Despite its alleged risks, Paraquat is not banned in the United States. However, it is restricted to licensed applicators. Over 30 other countries have either banned or restricted its use, raising questions about why it’s still permitted in the U.S.

What’s Next?

With ongoing lawsuits and studies, the link between Paraquat and Parkinson’s disease remains a hot topic. The outcomes of these lawsuits could set a precedent for future cases and possibly lead to stricter regulations.


The relationship between Paraquat and Parkinson’s disease is still under investigation, both scientifically and legally. However, the increasing number of Paraquat lawsuits indicates a growing concern about the herbicide’s safety. If you’ve been exposed to Paraquat, it might be time to explore your legal options.
