Paraquat Mass Tort

What is a Paraquat mass tort? When it comes to toxic chemicals, one name, in particular, stands out. Paraquat was first used as an herbicide in the 1960s. It was popular because of its ability to kill multiple plants at once and its low cost, making it inexpensive for many companies to purchase.

However, today this chemical is known to be highly toxic, which has caused many people to suffer injuries due to exposure to it. Many victims, who have been injured by exposure to Paraquat, are turning to the courts for justice. They are filing a mass tort lawsuit for compensation.


Understanding Paraquat Litigation


Paraquat litigation began in response to the injuries sustained by many people exposed to this chemical. Paraquat is a herbicide commonly used since 1963 on crops in the United States and other countries. It’s toxic to humans if ingested, inhaled, or absorbed through the skin, and it’s fatal to humans when ingested.

Although it was a popular weed killer, it has been linked to an increased risk of Parkinson’s disease and banned in 32 other countries due to the potential health risks.

If you or a loved one used Paraquat and were diagnosed with Parkinson’s disease, you may be entitled to compensation for the following:

  • Medical expenses
  • Pain and suffering
  • Lost wages and more

Filing a Paraquat Legal Claim

Paraquat is a weed killer first introduced to the U.S. in 1962. It is now used as a defoliant in vineyards and on cotton crops, among other things. Since early 2020, the U.S. National Toxicology Program (NTP) has investigated whether Paraquat causes Parkinson’s disease in humans. Multiple studies have linked Paraquat exposure to an increased risk of Parkinson’s disease in animals and farm workers. This degenerative movement disorder affects nearly one million Americans.

In one study published in January 2020, researchers found that women who lived near fields sprayed with Paraquat were about 2.5 times more likely to die from Parkinson’s disease than those who did not live near fields sprayed with this chemical. Those exposed to Paraquat poisoning may be at an increased risk of developing Parkinson’s disease. 

There is no known cure for Parkinson’s disease. Therefore, Paraquat Lawsuits are being filed throughout the country by people who have suffered serious health complications from exposure to the herbicide.

A Guide to Paraquat

Paraquat is a deadly herbicide that farmers and agricultural workers have used for decades. It’s a toxic chemical, and swallowing as little as one teaspoon of Paraquat can cause death. 


What Is Paraquat?

Paraquat is the common name for a chemical known as 1,1-dimethyl-4,4 bipyridinium dichloride. It is a nonselective herbicide that kills plants by causing oxidative damage in their cells. It was developed in the early 1950s by a team of scientists at Imperial Chemical Industries (ICI) in England. It was first introduced to the United States in 1961 by Chevron Chemical Company. Since then, it has become one of the most widely used herbicides globally.


How Is Paraquat Used?

Because it’s so dangerous, Paraquat can’t be used on crops or other places where it might come into contact with people. Licensed applicators or farmers only use it on farms or ranches to control weeds and grasses that compete with crops for water and nutrients. It has the following uses:

  • As a pre-harvest desiccant (sprayed on crops before harvest)
  • As a nonselective herbicide (to kill or prevent the growth of weeds)
  • As a postemergence weed control in row crops and orchards

It is also used to control invasive species in forestry, rangeland, and home gardens. Paraquat is toxic. It’s banned in more than 50 countries.


Common Paraquat Symptoms

Even though it is no longer produced in the United States, many people are still exposed to this dangerous substance through its use abroad or through older containers of Paraquat that have remained intact. Some of these symptoms include:

  • Coughing
  • Fatigue
  • Hives or rash
  • Rapid breathing
  • Shortness of breath
  • Swelling of the face or throat
  • Vomiting (sometimes with blood)
  • Wheezing

People who have worked on farms or landscaping companies often don’t even realize they’ve been exposed until symptoms develop later in life. 

How Can One Determine If Their Health Issues Are Directly Linked to Paraquat Exposure?

Determining a direct link between health issues and Paraquat exposure can be complex. Typically, individuals who suspect their health problems, especially Parkinson’s disease, are due to the herbicide Paraquat should first consult medical professionals. A detailed medical evaluation can identify symptoms consistent with those reported in Paraquat Parkinson’s disease lawsuits.

Additionally, a history of exposure to Paraquat dichloride, especially in agricultural settings, can be a significant indicator. Engaging with mass tort lawyers experienced in Paraquat class action litigation can provide guidance on the nuances of such cases. These lawyers can review medical bills, exposure history, and other evidence to build a strong case. The ongoing mass tort litigation, including the bellwether trials and the first Paraquat bellwether trial, can offer insights into how courts view the link between Paraquat and health issues.

The Environmental Protection Agency’s stance on Paraquat and its potential risks can also be a valuable resource. Ultimately, joining the Paraquat class action lawsuit or the Paraquat MDL class action can be a way to seek compensation if a direct link is established, potentially leading to Paraquat settlements for affected individuals.


If you consider filing a Paraquat lawsuit with a personal injury and truck accident attorney, the first step is to determine if you have been exposed to Paraquat and where you were exposed. Identify what symptoms you may be experiencing. The most common include:

  • Lung scarring (pulmonary fibrosis) — those who spray Paraquat are at risk for lung scarring because they inhale the chemical when sprayed on crop fields.
  • Skin irritation and blistering — many who worked closely are exposed to the chances of irritation and blistering when handling it.

According to the U.S. Environmental Protection Agency (EPA), Paraquat has not been manufactured or sold in the United States since 2007. However, it is still used as an herbicide in certain countries, such as Guatemala and Brazil. As such, there is still the risk of exposure.

Who Is Eligible to File a Paraquat Mass Tort Lawsuit?

Individuals who believe they have been harmed due to exposure to the herbicide Paraquat, particularly those diagnosed with Parkinson’s disease, may be eligible to file a Paraquat mass tort lawsuit. The link between Paraquat exposure and Parkinson’s disease has led to numerous Paraquat Parkinson’s disease lawsuits. As part of the mass tort litigation process, bellwether trial cases are selected to represent the larger group of Paraquat plaintiffs. These bellwether test trials can influence potential Paraquat settlement outcomes for all involved. It’s crucial to consult with mass tort lawyers familiar with the intricacies of Paraquat class action litigation to determine eligibility and potential compensation.

Hiring an Attorney for Paraquat Lawsuits

Although Paraquat has long been linked to Parkinson’s disease in scientific research, Paraquat lawsuits are a relatively recent occurrence. People are being made aware of how dangerous this chemical can be when misused. If they are not diligently protecting themselves from exposure in work settings, their risk of exposure and poisoning increases.
