According to the Parkinson’s Foundation, Paraquat, a commercial herbicide, can lead to Parkinson’s Disease following long-term exposure. The product is banned in 32 countries. However, In 2020, the Environmental Protection Agency renewed Paraquat for sale in the U.S. for the next 15 years. It continues to be legally available, although studies suggest it may be the culprit behind some Parkinson’s Disease cases. Parkinson’s Disease is a chronic degenerative disorder that affects the central nervous system and impairs motor functions. Symptoms include tremor, slow movement, difficulty walking, among other cognitive and behavioral problems. Several studies within the last 20 years show there may be a link between extensive exposure to Paraquat and the onset of Parkinson’s Disease related symptoms.
What is Paraquat?
First accessible in 1961, Paraquat’s primary use is as an herbicide for weed and grass control. It’s made by Syngenta, a global agriculture conglomerate that produces herbicides, pesticides, seeds and other agricultural products. The EPA classifies Paraquat as “restricted use,” meaning only for use by licensed applicators. In the US, Paraquat is primarily in liquid form. Since it’s highly poisonous, it’s brand identification is a blue dye to avoid confusion with other liquids. Additionally, an agent is active in Paraquat to induce vomiting if ingested.
Routes of Exposure to Paraquat
The most likely route of exposure to Paraquat is by swallowing the liquid, which would lead to poisoning. It easily mixes with food, water and other drinks. Poisoning is also possible through skin exposure, especially after long periods of time and if the skin is not intact (sores, cuts, rashes). Paraquat can also enter the system through inhalation. For instance, in the US, some marijuana contains Paraquat. Licensed users of Paraquat are more likely to be exposed.

Lawsuit Update
The case against Paraquat is growing rapidly. In 2022, the class action lawsuit for those harmed by Paraquat added more than 200 plaintiffs per month. For reference, at the start of 2022, the case had 482 plaintiffs with Parkinson’s Disease. By the end of 2022, there were 2,352 plaintiffs. The Federal Multi-District Litigation (MDL) was set for test trial in 2022 but is now postponed until October 2023 for depositions of expert witnesses.
The two main defendants of Paraquat are Syngenta and Chevron, Inc. One of the biggest suits is against Gramaxone, a brand name of Paraquat. Plaintiffs in this MDL allege that Gramaxone exposure led to the development of Parkinson’s Disease.
There is no settlement. The amount may be based by number of plaintiffs. As of right now, Paraquat cases are only in civil court, so only financial damages are recoverable.
