What is Paraquat?
Paraquat is a widely used but highly toxic herbicide known commercially as Gramoxone. It’s so potent that even a single sip can be fatal, and there’s no antidote. The EPA has warned that skin contact or inhalation could lead to Parkinson’s Disease years later, leading to numerous lawsuits against its manufacturers. Studies have shown that exposure increases the risk of developing Parkinson’s disease by up to 2.5 times.
Paraquat Poisoning: What You Need to Know
What causes it? You can come into contact with Paraquat if you accidentally eat or drink it, get it on your skin, or inhale it. Those at risk for paraquat exposure are primarily agricultural workers involved in applying, mixing, or loading the herbicide. The EPA has confirmed that exposure typically occurs during these activities and has set regulations for protective gear to minimize risks.
Being exposed to Paraquat is dangerous and can lead to poisoning. Symptoms include:
- Pain and swelling
- Stomach pain and vomiting
- Scarring in the lungs
- Failure of the heart, kidneys, or liver within days to weeks

Paraquats Link to Parkinson’s Disease
Recent research indicates a connection between exposure to pesticides like Paraquat and an increased risk of developing Parkinson’s disease.
Studies have shown that these chemicals can cause cellular disruptions akin to genetic mutations associated with Parkinson’s, particularly raising the risk for those already predisposed to the disease.
A 2019 review revealed that individuals exposed to Paraquat had a 25% higher risk of Parkinson’s, with prolonged exposure further increasing the risk. Among 31 pesticides studied, Paraquat was found to be especially harmful, generating toxic molecules that induce stress and damage cells, a process also seen in the degeneration of nerve cells in Parkinson’s.
Exposure to Paraquat during one’s teenage and young adult years was linked to a 200% to 600% increase in the risk of Parkinson’s, contingent on the duration of exposure.
Parkinson’s Disease Explained:
Imagine if your body started moving in slow motion, making everyday tasks like talking or walking suddenly difficult. That’s a bit like what happens with Parkinson’s disease, a health condition that affects how one moves. It starts off with barely noticeable changes, such as a slight tremble in the hand, but over time, it can lead to more serious difficulties like trouble walking or speaking. People with Parkinson’s can also experience changes in their mood, have issues with sleeping well, feel depressed, and face challenges with thinking or remembering things. While there’s no cure for Parkinson’s, there are treatments available to help manage these symptoms.
Symptoms include:
- Tremors: Shaking in hands, arms, legs, jaw, or neck.
- Stiffness: Muscle rigidity.
- Slowness: Movement becomes less swift.
- Balance Issues: Coordination problems leading to falls.
The Battle to Ban Paraquat
The EPA reviews herbicides every 15 years to ensure they meet safety standards. In 2017, they began a review of Paraquat.
The EPA’s 2019 human health risk assessment determined that Paraquat does not pose risks when used as directed. However, it highlighted potential risks to workers and bystanders from exposure and spray drift. Over 70 articles were reviewed, including studies on Paraquat’s link to Parkinson’s disease. In 2021, they released an interim decision not to ban Paraquat but suggested additional measures to reduce exposure risks.
While Paraquat remains legal, concerns about its safety persist, prompting calls for stricter regulations.
States like California are taking matters into their own hands. As the nation’s top user, they have moved to ban the weedkiller permanently. Assembly Bill 1963 would eliminate the use of Paraquat beginning in January of 2026.
