What Is Paraquat?

Paraquat dichloride, or Paraquat as it is commonly known, is a herbicide used to kill weeds, and control grass, and dry crops. This toxic chemical is usually available in liquid form but can also come in powder form. 

Paraquat products must contain a blue dye, a vomiting agent, and a strong odor to prevent accidental ingestion. The US Environmental Protection Agency (EPA) classifies Paraquat as “restricted use” due to the dangerous effects that exposure can cause.

Where Paraquat Exposure Can Occur

Over 30 countries have banned the herbicide due to its toxicity, but the US Environmental Protection Agency (EPA) re-approved its use. Although it is allowed to be produced and used here, Paraquat has strict federal regulations.

The herbicide is reviewed every 15 years to determine if the chemical is safe to use. Paraquat’s registration was re-approved by the EPA in July 2021.

Who Is At Risk of Paraquat Exposure?

Only certified applicators who have undergone specialized training can use the herbicide. These certified applicators are the most at risk of exposure to Paraquat. 

Paraquat is widely used by agriculture workers and licensed commercial users in the farming industry. It is used to maintain crops and clear land before harvest by drying out certain crops, such as cotton and soy. 

Nearby residential areas and farms that do not use Paraquat are also at risk of exposure. Runoff and crop overspray can lead to contamination of surrounding air, water, and soil.

Paraquat drift occurs when the herbicide is sprayed and carried through the air to unintended areas. People nearby can breathe it in and get their clothes contaminated with the chemical.

It is illegal to produce and sell Paraquat products to homeowners for residential use. Commercial users are also not allowed to spray the herbicide in any residential areas.


Paraquat is naturally odorless and tasteless. If the Paraquat herbicide is produced without the required blue dye and odor additives, it can easily be mistaken for a drink. 

Without the additives, Paraquat can also be undetectable if mixed with food. In the past, before the requirements for the production of Paraquat were put in place, ingestion of the herbicide was more likely to occur.

You may breathe in Paraquat if there is a herbicide container nearby. Overspray is another method of exposure. 

If the spray is a fine mist, Paraquat drift can occur, causing nearby people and animals to inhale the herbicide. Inhaling Paraquat can cause severe damage to your lungs

Skin Exposure

If your skin contacts Paraquat, you must wash the area immediately. Prolonged exposure can lead to Paraquat poisoning. Severe effects are also likely if you have cuts or rashes on the exposed skin.

Side Effects of Paraquat

The high level of toxicity from contact with Paraquat can result in a range of different side effects that can even include death. Immediate side effects that a person who has ingested Paraquat will have are pain and swelling in the mouth and throat. 

The side effects that follow are some that signal the Paraquat has entered the gastrointestinal tract. You may experience nausea, vomiting, diarrhea, and abdominal pain. 

It is rare for people who have ingested Paraquat to survive.

Long-term side effects such as organ damage may persist for those who survive. Long-term side effects can include heart failure, liver failure, and kidney failure.

Scientific Studies on Exposure to Paraquat

There are also findings from numerous studies which conclude that Paraquat is linked to Parkinson’s disease. These findings sparked the initial Paraquat class action lawsuits

A recent study from September 2021 focused on pregnant women who have been exposed to Paraquat. The study concluded that exposure to Paraquat during pregnancy could cause neurodevelopmental defects in a developing fetus. 

The defects found were similar to genetic changes seen in those who have Parkinson’s Disease.

Paraquat’s Link to Parkinson’s Disease

Paraquat exposure can lead to impaired function of certain areas of the brain that produce dopamine and can cause mutations in the cells. Long-term exposure to the herbicide paraquat has been linked to individuals developing Parkinson’s Disease.

Parkinson’s Disease is a disorder that can affect an individual’s brain function. Parkinson’s Disease causes deterioration of brain cells which affect the parts of the brain that control movement and activity of the body. 

Someone who has Parkinson’s Disease will most likely experience tremors, muscle stiffness, dizziness, and problems with balance. Many scientific studies have been done that suggest a link between Paraquat and Parkinson’s Disease. 

One Agricultural Health Study concluded that farmers who use Paraquat are at a higher risk of developing early Parkinson’s Disease. Many certified applicators have been exposed to Paraquat for years and have developed early Parkinson’s Disease.

Manufacturers Face Paraquat Lawsuits

There are over 700 Paraquat lawsuits that manufacturers face due to exposure’s adverse effects. Many of the plaintiffs that have filed a lawsuit are US farmers and certified applicators who have experienced prolonged exposure to Paraquat and have developed Parkinson’s Disease.

Paraquat Lawsuit Attorneys
Syngenta and Chevron Chemical Company are two manufacturers facing Paraquat MDL (multidistrict litigation) trials. Paraquat is sold under several brand names that may sound familiar. These brand names include:

  • Gramoxone
  • Parazone
  • Firestorm
  • Quick-Quat
  • Para-Shot 3.0
  • Devour
  • Helmquat 3SL
  • Cyclone SL 2.0
  • Dexuron
  • Bonedry
  • Blanco

The most popular brand name, Gramoxone, has been sold by Syngenta for decades and was distributed by Chevron before 1986. Plaintiffs claim that Syngenta and Chevron knew about studies that revealed there is a link between Paraquat and Parkinson’s Disease, and they were negligent in failing to warn users.

New studies being conducted, including defects in developing fetuses and Parkinson’s Disease in adults, show that there may be substantially more potential Paraquat cases. The number of plaintiff cases in the Southern District of Illinois Court may grow significantly in years.

Is There a Deadline to File Paraquat Lawsuit?

There are statutes of limitations in each state for product liability cases. In Illinois, people have two years to file a lawsuit, but the deadline does not apply to those exposed to toxins that caused a latent disease. 

Are the Paraquat Claims Part of a Class Action Lawsuit?

There are hundreds of Paraquat lawsuits, but they are not part of a class action. They have been consolidated into Multi-district litigation (MDL). 

A class-action suit involves similar claims against a product and is treated equally. In an MDL, the claims are consolidated but treated individually. 

Paraquat MDL Lawsuits

The Paraquat Products Liability Litigation MDL was put in place on June 8, 2021, headed by Chief Judge Nancy Rosenstengel of the Southern District of Illinois. 

On June 7, 2021, the US Judicial Panel on Multidistrict Litigation (JPML) ordered all Paraquat lawsuits that have been filed in federal courts to be consolidated into the Southern District of Illinois for pre-trial proceedings.

Chief U.S. District Judge Nancy Rosenstengel is overseeing Illinois district court proceedings. In February 2022, Judge Rosenstengel denied Syngenta and Chevron’s motions to dismiss the plaintiffs’ claims under Minnesota law and their public nuisance claims.

The court has set bellwether trials from a pool of cases involving plaintiffs and defendants. A bellwether trial is a test trial that consists of a case or a select number of cases from a larger pool of lawsuits that are filed against the same defendants. 

The bellwether trials will allow Paraquat plaintiffs and the defense to undergo proceedings in the district court with the representative group of cases. The first bellwether trial is scheduled for November 15, 2022.
