UPDATE: Crop-Duster Files Paraquat Parkinson’s Disease Lawsuit in Illinois

In December 2020, a former crop duster with Parkinson’s disease filed a Paraquat lawsuit blaming his illness on repeated exposures to Paraquat from 1969 to 1981 when it was sprayed on farm fields in Wisconsin and Illinois. The lawsuit was filed against Chevron, Syngenta, and Growmark.

The Parkinson’s Disease Lawsuit (PDF) was filed on December 21, 2020 in St. Clair County, Illinois — Case No. 20L1006.

Farm-Worker Are Filing Paraquat Lawsuits for Parkinson’s Disease

More than a dozen people with Parkinson’s disease have filed lawsuits against the manufacturers of Paraquat. The lawsuits claim that companies like Syngenta, Chevron, and Growmark did not provide adequate warnings about the health risks of Paraquat.

The first Paraquat lawsuit was a class action that was filed in October 2017 in St. Clair County, Illinois, by 3 farmers with Parkinson’s disease. One of the farmers, Thomas Hoffmann, died 23 days after filing the lawsuit. More recently, in April 2019, a group of Paraquat lawsuits were filed in California state court by 10 men with Parkinson’s disease.

Who Is At Risk?

  • People who live in rural areas where Paraquat is sprayed on crops
  • Farmers and farm-workers
  • Pesticide applicators
  • People who handle Paraquat for a commercial business

What is Paraquat?

Paraquat is a highly-toxic herbicide (plant-killing chemical) that has been on the market since 1961. Paraquat is also known under the brand-name Gramoxone® or paraquat dichloride. Today, Paraquat is used to control weeds on more than 100 types of crops.

Paraquat Banned in 32 Countries — But Not the U.S.

Paraquat was banned by the European Union in 2007. At least 32 countries have banned Paraquat because it is so dangerous, but the U.S. still allows licensed commercial companies to spray Paraquat.

What is the Problem?

Paraquat is extremely toxic to the human body, including the lungs, liver, kidneys, heart, and brain. Just a single sip can be deadly. Mark Davis, senior officer for pesticide management at the United Nations, warns: “It’s terribly toxic. Once it is in your body there is no antidote.”

How Are People Exposed?

  • Ingestion or drinking the chemical
  • Occupational exposure
  • Exposure to agricultural pesticides
  • Skin contact
  • Breathing it in the air

Studies Linking Paraquat and Parkinson’s Disease

In 2009, two studies in California’s Central Valley found that people had an increased risk of Parkinson’s disease after years of exposure to Paraquat and another herbicide called Maneb. People who were exposed as teenagers or young adult had a 200% to 600% increased risk of Parkinson’s disease, with a higher risk linked to a greater overall number of years of exposure to Paraquat.

In 2011, the Agricultural Heath Study found a 200% increased risk of Parkinson’s disease among farmers who mixed or applied Paraquat. The authors of the study concluded: “Paraquat use plays a role in human Parkinson’s disease. Because Paraquat remains one of the most widely used herbicides worldwide, this finding potentially has great public health significance.”

Toxic Risks of Paraquat Spark Marijuana Health Scare in 1970s

The toxic effects of Paraquat have been known for decades. Back in the 1970s, Paraquat created a public health scare in the U.S. when the Mexican government used U.S.-funded airplanes to spray Paraquat on illegal marijuana and opium poppy fields. The growers sold the poisoned plants to consumers in the U.S. — and many of them suffered permanent lung disease and other side effects.

Immediate Signs & Symptoms of Paraquat Exposure

Ingesting a small amount of Paraquat can lead to heart failure, kidney failure, liver failure, and lung scarring within several days or weeks.

Ingesting larger amounts of Paraquat can cause severe symptoms within days, including kidney failure, confusion, coma, heart damage, liver failure, lung scarring, muscle weakness, fluid in the lungs, breathing failure, seizures, and death.

Long-Term Health Risks of Paraquat Poisoning

If a person survives the toxic effects of Paraquat poisoning, they may develop long-term health problems, such as:

  • Brain damage
  • Permanent lung damage (scarring)
  • Kidney failure
  • Heart failure
  • Esophageal strictures (scarring of the swallowing tube that makes it hard for a person to swallow)
  • Other severe side effects

What is Parkinson’s Disease?

Parkinson’s disease is a brain disorder that can lead to shaking, stiffness, and trouble walking and talking. The symptoms gradually worsen as the disease damages the part of the brain that controls movements.

Symptoms of Parkinson’s Disease

  • Tremor (trembling) in the hands, arms, legs, jaw or head
  • Stiffness of the arms, legs, and abdomen
  • Slow movement
  • Problems balancing and coordinating movements, which sometimes leads to falls
  • And more

Non-Motor Symptoms of Parkinson’s Disease

  • Depression
  • Fatigue
  • Behavior changes
  • Constipation
  • Sleep problems
  • Memory problems
  • Loss of sense of smell
  • Cognitive impairment
