Paraquat herbicide and Parkinson’s disease

May. 22, 2022

There is a body of peer reviewed scientific evidence has positively identified exposure to a herbicide called paraquat, which is widely used for weed and grass control, be implicated in changes in the brain associated with the symptoms of Parkinson’s disease.

Exposure to paraquat can occur through direct use and application, or simply by proximity to areas which have been treated.

In America, litigation is already underway against some of the manufacturers of paraquat products, including Syngenta, Chevron and Growmark. Those proceedings allege, amongst other things, that the paraquat products made by those manufacturers were defectively designed and did not perform safely because of the likelihood that their use and absorption would lead to neurodegenerative disease including Parkinson’s disease.

It is also alleged that the manufacturers negligently failed to carry out adequate research and testing in relation to the impact of paraquat and failed to provide adequate warning of its risks.

Australian Law firm, Maurice Blackburn Lawyers is investigating the link between paraquat and the development of Parkinson’s disease.

You may wish to contact Maurice Blackburn Lawyers if you have been exposed to paraquat and you think that you have experienced neurodegenerative changes, such as the development of a resting tremor or a slowing of speech or movement, or you have been diagnosed with Parkinson’s disease.
