Were You Exposed to Paraquat and Diagnosed with Parkinson's Disease?

Scientific Research on Paraquat and Parkinson’s Disease

Paraquat, sold under brands like Gramoxone, is a restricted-use herbicide in the U.S., available only to certified applicators. It is banned in more than 70 countries, including the European Union, China, and the U.K., due to health concerns.

Scientific studies have investigated potential links between Paraquat exposure and Parkinson’s disease, a progressive neurological condition affecting movement and other functions.

Notable research includes:

• The Farming and Movement Evaluation (FAME) study, which reported an association with 2.5 times higher odds of Parkinson’s in exposed individuals.

• Meta-analyses of observational studies showing an overall increased risk, with estimates around 1.6 times higher odds, and higher in some cases of prolonged exposure.

• Laboratory research indicating Paraquat can cause oxidative stress, affecting dopamine-producing brain cells in models.

Ongoing research continues to examine these associations.

Potential Exposure Scenarios

Individuals who may have been exposed include:

• Farmers and farmworkers involved in mixing, loading, or applying Paraquat

• Licensed commercial applicators

• Landscapers, groundskeepers, or nursery workers

• Residents near agricultural areas where Paraquat was used (potential drift exposure)

Exposure can occur through direct handling, inhalation, skin contact, or environmental pathways.

If you have a Parkinson’s diagnosis and a history of potential Paraquat exposure, your situation may warrant further review.

Current Status of Paraquat Lawsuits (as of late 2025)

Thousands of lawsuits have been filed alleging links between Paraquat exposure and Parkinson’s disease. Over 6,470 cases are pending in federal multidistrict litigation (MDL) in the Southern District of Illinois, with additional cases in state courts.

In April 2025, the parties announced a tentative framework to resolve many federal claims, with negotiations ongoing. Proceedings have been paused into early 2026 to allow for potential resolution.
