Paraquat Parkinson’s Lawyer


Long-term exposure to Paraquat has been linked to the development of Parkinson’s disease. California lawsuits have been filed against the manufacturers of Paraquat on behalf of plaintiffs ranging from farmworkers to people who were exposed because they live close to fields where the herbicide was used.

If you have been diagnosed with Parkinson’s disease following exposure to Paraquat, call us from anywhere in the nation at (800) 404-5400. If you are within the Sacramento agricultural region, dial our local number: (916) 921-6400.

Paraquat – What is it, and How is it Used?

Paraquat was first sold in the United States in the 1960s. It is a toxic substance used as an agricultural weedkiller or herbicide.  As a non-selective herbicide, it destroys all leafy green plants. It was used by the U.S. government and the Drug Enforcement Administration (DEA) in Mexican marijuana and poppy (heroin) fields in the 70s. It is also currently used on crops such as almonds and cotton that do not rely on their leaves for survival. It is applied via an aerosol spray disbursed by crop duster planes, helicopters, or tractor-drawn sprayers.

The History of the Herbicide

Imperial Chemical Industries (ICI), an England-based company, originally developed and marketed the weed killer. Subsequently, ICI and Chevron entered an agreement that made Chevron the only U.S. distributor of Paraquat. That contract ended in 1986, and ICI (now a subsidiary of Switzerland-based Syngenta) started selling Paraquat in America and continues to do so. Some of the brand names under which Paraquat is sold include:

  • Gramoxone
  • Ortho
  • Ortho Plus

The use of Paraquat is banned in 32 countries. The United States, however, is not one of them. The herbicide has been banned since 2013 throughout the European Union. Although Syngenta, a huge Swiss company, produces Paraquat, the use of the substance in Switzerland has been prohibited since 1989. Syngenta was purchased by ChemChina, and in 2012 the Chinese mega-company announced that it was ending domestic use of Paraquat for safety reasons. Still, they continue to export the dangerous chemical.

The Michael J. Fox Foundation, an organization dedicated to finding a cure for Parkinson’s disease, believes that the Environmental Protection Agency (EPA) should ban Paraquat and protect Americans from potential exposure to dangerous substances.

Paraquat Use in the United States

Paraquat is a Restricted Use Product (RUP) that licensed applicators can use only. It is most commonly used as an alternative to Roundup, the Monsanto herbicide that has experienced legal issues with consumer claims that it causes cancer. More and more plants and pests have become resistant to Roundup, which has caused farmers to seek out other herbicides to apply to their crops.  As such, in recent years, the use of Paraquat in the U.S. has skyrocketed.  In 2011, more than 3 million kilograms of Paraquat were used. By 2017, that number had more than doubled to 7 million kilograms.

California Leads the Nation in the Use of Herbicide

California leads the nation in using Paraquat, using nearly 2 million kilograms more per year than Texas, which ranks second in using the herbicide. Within California, the Greater Sacramento region and Central Valley have the highest concentration of Paraquat use. Those who regularly work with the herbicide or live close to heavily used areas have the highest exposure risk.

Of the counties that have historically used the most Paraquat, the top eight are in California:

  • Fresno
  • Kern
  • Kings
  • Tulare
  • Merced
  • San Joaquin
  • Madera
  • Stanislaus
Paraquat and Parkinson’s

Research has revealed that long-term exposure to the toxins within Paraquat increases the risk of Parkinson’s disease. As the use of Paraquat has increased, the prevalence of Parkinson’s has also. Diagnoses of early-onset Parkinson’s jumped by more than 100% from 2013 to 2017.

Paraquat is incredibly toxic – ingesting a mere teaspoon of the substance is fatal for a human adult. Exposure to its aerosol droplets can have devastating effects on the human nervous system.

Studies have revealed that exposure to Paraquat puts people at an increased risk of developing Parkinson’s later in life. For teens and young adults who have been exposed, the risk increases by 200 to 600 percent, depending on how long they had exposure. Farmers who had used Paraquat were determined to be 200% more likely to be diagnosed with Parkinson’s disease.

Researchers believe Paraquat affects dopamine levels in humans when absorbed through the skin or respiration. Dopamine reduction is a hallmark of Parkinson’s disease.

Parkinson’s Disease – Symptoms

Parkinson’s disease is a degenerative neurological disorder caused by neuron loss and the resulting loss of dopamine, a neurotransmitter. It is believed that both genetics and environmental factors play roles that lead to neuron death.  Although treatments can slow the progression of the disease and treat some of its symptoms, there is no cure for Parkinson’s.

Parkinson’s disease presents in five stages, with symptoms increasing at each stage.

  • Stage One: Mild symptoms, such as a unilateral tremor or slight change in gait. Daily life is usually not affected in this stage.
  • Stage Two: Symptom progression could include tremors becoming bilateral. Daily tasks may become more complicated.
  • Stage Three: Recognized as the mid-stage of Parkinson’s, one’s balance may be affected, and movement may significantly slow. Daily tasks become more of an obstacle and the fall risk increases.
  • Stage Four: Symptoms reach the point where the person will require assistance with their daily tasks and cannot live alone.
  • Stage Five: Advanced stage symptoms include leg stiffness that prevents the person from standing or walking. Twenty-four-hour care will be necessary.

There are four primary motor symptoms of Parkinson’s, of which only one or two may be present in the early stages. As it is a progressive disease, symptoms continue to develop over time. The four primary symptoms are:

  • Resting tremor
  • Muscle rigidity
  • Bradykinesia – reduction of fine motor control
  • Postural instability or impaired balance. This becomes more noticeable in later stages.
What Does the EPA Say?

In 2017, the Unified Parkinson’s Advocacy Council requested that the EPA reject the re-registration of Paraquat because of the harm it causes to human health. In its request, the council included studies showing a link between low-level Paraquat exposure and an increased risk of Parkinson’s.  Additionally, a bill was introduced in Congress in July 2019 to try to end the sale of Paraquat in the United States.

The EPA has acknowledged that Paraquat is highly toxic and dangerous.  The agency announced in 2016 that it would be further exploring the dangers and health risks of the chemical, specifically the epidemiology data about Paraquat use and its relationship to Parkinson’s disease.

In 2020, the EPA proposed additional safety regulations to limit exposure to Paraquat to mitigate health risks. The new measures included using PF10 respirators, enclosed cabs, and disallowing aerial applications for nearly all uses and locations.

Paraquat Lawsuits

The manufacturer’s negligence must be established when pursuing a personal injury claim against a product manufacturer. The manufacturers and marketers of Paraquat must protect consumers that use their products. The dangers of the weedkiller are well known, as evidenced by the conclusions of many studies, the EPA’s recommendations, and the fact that the herbicide is banned in several other countries.

A Paraquat lawsuit can help you recover money for the medical harm and financial damages you have suffered due to your exposure to the product. Each case is different, but some of the categories of monetary damages that may be available to you include:

  • Medical expenses – both those already incurred and those recommended by a physician for the future
  • Lost income and loss of earning capacity
  • Non-economic damages, including pain and suffering
  • If applicable, loss of consortium damages may be available to the spouse of the injured person

Pursuing legal action against the makers of Paraquat will not prevent or reverse the physical hardships caused by a diagnosis of Parkinson’s disease. However, the money can improve your quality of life, considering the lifetime costs associated with a degenerative disease such as Parkinson’s.

Large, profitable chemical corporations that sell dangerous products to the American consumer should be held accountable for the damage that their products cause. Most of the time, the only way to hold them accountable is by pursuing a civil lawsuit against the company.
