Paraquat Lawsuit Linking the Herbicide to Parkinson’s Disease Continues

| Read Time: 3 minutes

Paraquat was developed in the 1960s and has continued to grow in popularity as weeds have become more resistant to other products. However, recent studies have shown that symptoms of Paraquat exposure can lead to increased risk of Parkinson’s disease.

According to the National Institutes of Health, Paraquat users are up to 2.5 times more likely to develop Parkinson’s than non-users. As of October 2021, there were 329 Paraquat lawsuits pending nationwide..

In addition, research concluded that exposure to Paraquat herbicide can cause prenatal neurodevelopmental toxicity similar to Parkinson’s disease. This new information, released in September 2021, is significant news as it’s the first research showing Paraquat potentially leading to prenatal health defects

The highly poisonous liquid weedkiller is typically marketed with a blue dye and a strong odor and has become highly regulated with enhanced protection mandates outside of the United States. In fact, Paraquat is banned in 32 countries.

Despite its negative impact on public health, Paraquat usage is expected to continue to increase across the United States. In 2020, the Environmental Protection Agency (EPA) reapproved continued use of the chemical for another 15 years, a decision that drew heavy criticism from environmental and public health organizations.

While Paraquat remains legal, the EPA has deemed it a restricted-use chemical, which means only commercially licensed applicators can use Paraquat.

Paraquat Herbicides Linked to Parkinson’s Disease

People diagnosed with Parkinson’s disease reported they were exposed either directly through working with the weed killer or by proximity to land that was treated with Paraquat. . The link to Parkinson’s is linked to herbicides that are identical to Paraquat, but have been manufactured under names like:

  • Blanco
  • Bonfire Herbicide
  • Devour
  • Firestorm
  • Gramaxone
  • Helmquat
  • Para-SHOT
  • Parazone
  • Quik-Quat

What Are the Symptoms of Parkinson’s Disease?

One of the most worrying aspects of Parkinson’s is how easily and often the disease can go undetected throughout its early phases. However, the condition will almost always become noticeable, with the following common symptoms of herbicide exposure:

  • Tremors in the hands, fingers, and limbs
  • Rigid muscles or stiffness
  • Slowed movements such as getting out of a chair or taking shorter steps while walking
  • Impaired speech, including slurring and hesitation
  • Impaired balance
  • Writing changes (difficulty writing, small writing, general shaking of the hands)
  • Impairment of unconscious movements such as smiling

Parkinson’s is a disease that worsens with time. However, there is treatment available to help lessen and slow down symptoms from progressing. This can lead to other symptoms such as anxiety, depression and difficulty sleeping.
