Paraquat herbicide exposure in a New York farm town has been linked to Parkinson’s disease, raising urgent concerns about the safety of this widely used chemical. For decades, tenant farmers sprayed paraquat on fields in Hebron, New York, and now residents like Gordon Chaplin are facing devastating neurological diagnoses. This article explores the evidence, the community’s struggle, and the regulatory actions being taken.
What Is Paraquat and Why Is It Used?
Paraquat is a highly toxic herbicide used to kill broadleaf weeds and grasses. It is one of the most widely used herbicides in the United States, especially in agriculture. However, it is banned in more than 50 countries due to its severe health risks.

The chemical is applied to crops like corn, soybeans, and cotton, and it can persist in the environment for years. Farmworkers and nearby residents may be exposed through inhalation, skin contact, or contaminated water.
The Link Between Paraquat and Parkinson’s Disease
Numerous studies have shown a strong association between paraquat exposure and Parkinson’s disease. The herbicide is known to cause oxidative stress in brain cells, leading to the degeneration of dopamine-producing neurons, which is a hallmark of Parkinson’s.
In Hebron, Gordon Chaplin and 14 of his neighbors have been diagnosed with Parkinson’s, a cluster that has alarmed health experts. Sarah Teale, Chaplin’s wife, calls the area “Parkinson’s Valley” and believes paraquat is the common denominator.

Scientific Evidence and Research
Research published in the journal Environmental Health Perspectives found that individuals exposed to paraquat had a 2.5 times higher risk of developing Parkinson’s. Another study from the National Institutes of Health confirmed that paraquat triggers the same cellular mechanisms that cause Parkinson’s in humans.
While the chemical industry argues that paraquat is safe when used correctly, the growing body of evidence has led to legal action. Thousands of lawsuits have been filed against manufacturers like Syngenta, alleging they failed to warn about the Parkinson’s risk.
Regulatory Actions and Bans
Paraquat is banned in the European Union, Brazil, and many other countries. In the U.S., the Environmental Protection Agency (EPA) has faced pressure to restrict its use. In 2024, 14 states introduced bills to limit or ban paraquat, and Vermont became the first state to pass a ban.
However, federal action has been slow. The EPA re-approved paraquat in 2021, citing insufficient evidence of harm, but the agency is under court order to review its decision.

What Can Affected Communities Do?
For residents like those in Hebron, the immediate need is medical support and legal recourse. If you or a loved one has been diagnosed with Parkinson’s after paraquat exposure, you may be eligible for compensation.
It’s also important to avoid using paraquat on your property and to test well water for contamination. Community advocacy and pressure on regulators can help speed up necessary bans.
Comparison of Paraquat Regulations by Country
| Country | Status | Reason |
|---|---|---|
| United States | Restricted use | Still legal, but under review |
| European Union | Banned | Health and environmental risks |
| Brazil | Banned | High toxicity and poisonings |
| Vermont (USA) | Banned | First state to ban in 2024 |
