Over the years we have developed many different methods to improve the growth of our crops and to eliminate weeds. One such way that has been practiced for many years is the use of herbicides. Herbicides kill weeds and allow the plants that we want to grow to flourish without competition. However, some herbicides, such as Paraquat, pose risks to the people who use them. There is mounting evidence of the dangerous nature of Paraquat, and its link to the development of Parkinson’s Disease is becoming clearer every day.
If you’ve developed Parkinson’s Disease as a result of Paraquat exposure, a Paraquat lawyer can help you receive all of the money to which you are due. Read more about the Best kratom for anxiety.
Paraquat and Parkinson’s Disease:
Paraquat does not contain MPTP. Paraquat is structurally similar to MPP+, the toxic metabolite of MPTP. Further, MPTP is used by researchers who study Parkinson’s Disease, as it can reliably cause the symptoms of PD when it is introduced to lab animals.
Parkinson’s Disease is characterized by 4 “cardinal signs”. These include tremors, slow movement, rigid muscles, and instability. These signs are also being seen in those who have been exposed to Paraquat.
Other Issues Associated with Paraquat Exposure:
While Parkinsonian symptoms are generally considered to be the main side effect of Paraquat exposure, there are other potential risks as well.
One such potential issue is birth defects, which have been correlated with herbicide. While this research is still ongoing, it appears that Paraquat may be associated with some common and devastating developmental issues.
Additionally, certain cancers have been linked to Paraquat. Again, this is research that needs further investigation but just adds to the mountain of evidence suggesting that Paraquat is unsafe for human contact.
Who May Be Affected by Paraquat?
Those who work directly with the herbicide are obviously at high risk. These include farmers, groundskeepers, and others in similar occupations. However, these individuals are required to follow EPA-approved practices when handling the substance, so they minimize harmful interaction with Paraquat.
Unfortunately, Paraquat can negatively affect those who live near facilities that use Paraquat. These individuals, such as people living near farms, children attending school near these facilities, etc. can all be exposed through two common phenomena:
- Pesticide Drift: Pesticide (or herbicide) drift is a natural occurrence. This happens when someone who is applying the substance sprays the appropriate amount in a given area, but the wind spreads it far and wide to nearby communities and homes.
- Overspray: On the other hand, overspray is due to human error. This occurs when the person applying the Paraquat sprays too much of the substance in a given area, allowing it to spread farther than intended.
What You Should Do If You Believe You Qualify for a Paraquat Lawsuit:
If you believe you’ve been exposed to Paraquat and developed Parkinson’s Disease, as a result, reach out to a lawyer and file a Paraquat lawsuit today. These cases are tricky to navigate, and having an experienced lawyer on your side will make the process much easier.
What Is Paraquat?
Paraquat is a weed killer. It has been sold since the 1960s under the brand name Gramoxone. It is one of the most widely used weed killers in the world. In the United States, the EPA lists paraquat as a restricted-use pesticide. This means only licensed applicators can buy and use it. Workers must wear full safety gear when they handle it. The European Union banned paraquat in 2007. Dozens of other countries have also banned it. The main makers named in lawsuits are Syngenta and Chevron.
A Note About Paraquat and MPTP
Paraquat does not contain MPTP. MPTP is a different chemical. MPTP is a toxic contaminant found in some street drugs. Researchers use MPTP in lab animals to study Parkinson’s disease. Paraquat is not MPTP. But paraquat is close in shape to a chemical called MPP-plus. MPP-plus is the toxic form that MPTP turns into in the body. This is one reason researchers study paraquat and Parkinson’s disease.
The 2011 Study That Linked Paraquat to Parkinson’s Disease
In 2011, a study from the United States National Institutes of Health looked at farmers and their families. The study is known as the FAME study. It found that people who used paraquat had about 2.5 times the risk of Parkinson’s disease as people who did not use it. The study also found a higher risk for people who used rotenone, another pesticide. Lawsuits point to this study and other research as key proof. The research does not prove that paraquat alone causes Parkinson’s disease. But it shows a strong link between the chemical and the disease.
The Paraquat Lawsuits: What Has Happened
In June 2021, the federal courts grouped paraquat lawsuits into one case. The case is known as MDL No. 3004. It is heard in the Southern District of Illinois. Thousands of people filed claims. Most of them are farmers, farm workers, and groundskeepers. They say they got Parkinson’s disease after working with paraquat. The lawsuits are against Syngenta and Chevron. The companies have denied that paraquat causes Parkinson’s disease. The court tests a small number of cases first. These test cases are called bellwether trials. The results help both sides judge the value of the other cases.
What You Need to File a Paraquat Lawsuit
| Proof You Need | Why It Matters |
|---|---|
| Proof of exposure to paraquat | Job records, farm records, purchase receipts, or a work history that shows you used or worked near paraquat |
| A Parkinson’s disease diagnosis | Medical records from your doctor that show the diagnosis and the date |
| A timeline | Records that show your exposure came before your symptoms started |
| Witnesses | Co-workers, family, or farm managers who can confirm your work with paraquat |
Steps to Take If You Think You Qualify
- Write down your work history. List the farms, the years, and the chemicals you used.
- Collect your medical records. Keep every report, test, and prescription.
- Do not throw away old work papers, pay slips, or chemical records.
- Talk to a product liability lawyer. Ask if the lawyer has handled paraquat cases before. Ask about the time limit for your claim.
- Do not sign any paper from a chemical company or insurer before your lawyer checks it.
