Lawmakers Seek to Ban Paraquat Due to Links with Parkinson’s Disease

Peter Angelos Law is investigating potential claims related to Paraquat exposure and a subsequent diagnosis of Parkinson’s disease. Studies have detected an association between Paraquat exposure and Parkinson’s disease. Paraquat dichloride (paraquat) is a chemical agent most commonly used as a herbicide by farmers, ranchers, herbicide applicators, groundskeepers, gardeners, municipal workers, as well as others. If you or a loved one was exposed to Paraquat and were subsequently diagnosed with Parkinson’s disease, please contact a lawyer at Peter Angelos Law.

What is Paraquat and What is the Connection to Parkinson’s?


Paraquat, also known as “paraquat dichloride,” is a commonly used herbicide in the United States regarding the control of weeds as well as for the desiccation of crops, such as cotton, before harvest. Due to its high toxicity content, not only does paraquat have harmful effects on weeds and crops, but can also harm humans. After studies in the early to mid-2000’s provided inconclusive data regarding whether or not there was a link between paraquat and Parkinson’s Disease, more recent studies have been able to prove a positive correlation. A study performed in 2018 discovered that minimal exposure to pesticides such as paraquat can lead to a disruption of human cells that could mimic the mutations that are known to cause Parkinson’s. Along with a predisposition for Parkinson’s, these effects could further increase one’s chances of developing the disease later on in life. A following study from 2019 concluded that there is a 25% greater chance of developing Parkinson’s Disease for one who is frequently exposed to the paraquat pesticide, as well as an even greater regularity for those who are exposed to the toxic chemical for longer periods of time.

The EPA’s Slow Response to Act on Paraquat’s Harmful Effects

The Environmental Protection Agency, more commonly known as the EPA, has taken quite a slow and timid approach when it comes to its response on paraquat and its harmful effects on humans. Even though they have stated that paraquat is indeed toxic and at times fatal, the EPA has yet to take legal action regarding the use of paraquat in the United States. In 2019, the EPA reviewed dozens of articles surrounding paraquat and its health risks, yet still concluded that there was insufficient evidence that could link the appropriate labeled use of paraquat and the risk of Parkinson’s Disease. However, in October of 2020, the EPA did institute several additional protections in the hopes of reducing paraquat exposure, including limiting the use of paraquat to only licensed applicators. 

Lawmakers Intentions to Ban Paraquat in the United States

In response to the growing connection between the use of paraquat and the risk of Parkinson’s Disease, as well as the weak efforts on part of the EPA, many lawmakers around the United States have decided to take action. In July of 2019, the Protect Against Paraquat Act of 2019 (HR 3817) was introduced. This bill intends for the EPA to ban the use of paraquat on all food, cancel the registration for all paraquat uses, as well as prohibit the use and sale of current paraquat stock. Other governing bodies, such as those of China and the European Union, have already banned the use of paraquat and lawmakers in the United States hope to follow suit.
