Numerous Cases Filed Against Syngenta Over Link Between Paraquat and Parkinson’s Disease

If you have been diagnosed with Parkinson’s Disease due to the use of Paraquat, you have the right to file a lawsuit against the negligent manufacturer. Currently, there are 157 cases across the country about to be heard in both state and federal courts. The lawsuits allege that Syngenta, the Chinese-owned chemical company based in Switzerland, knew about the risk of Parkinson’s but gave no warning to consumers. Other defendants in the lawsuit are Chevron Phillips Chemical Company LP and Chevron USA.

Syngenta and Chevron Deny Accusations

 Paraquat has been used in this country since the 1960s but is banned in 30 other countries around the world. Parkinson’s is an incurable and debilitating disease. The disease makes it difficult for a sufferer to control their movements and leads to tremors in many cases. Syngenta, which has sold Paraquat for over 50 years, insists its product is safe.

Introduction of Paraquat into the United States

Despite scientific evidence linking paraquat to Parkinson’s, the defendants deny liability. The use of a paraquat-based weed killer dates back to the early 1960s. At that time, Chevron had an agreement with Imperial Chemical Industries. The company used a paraquat-based chemical called Gramoxone. 


The first trial case, Hoffman v. Syngenta, was set for May 10 in Illinois. The lawyer said that he had documents that proved Syngenta knew about the link to Parkinson’s for decades and made no move to warn customers. The plaintiffs are residents of Illinois who were exposed to the pesticide along with their spouses. It is rumored that a settlement might be in the works for this case, but that has not been confirmed by legal representatives. 

Federal Lawsuit

A federal judge has been chosen in the Illinois Southern District to coordinate the lawsuits. In June 2021, a U.S. judiciary panel approved the consolidation of the lawsuits. The multidistrict litigation that involves 77 cases with possible add-ons in 16 districts is pending. Scientific and regulatory issues are part of the cases. The reason for consolidation is to reduce repetitious discovery, monetarily reduce the strain on the plaintiffs and avoid pretrial rulings at odds with one another. U.S. Judge Nancy Rosenstengel set the first trial for November 15, 2022. 

Case Settlements Started

Settlements are beginning in the Paraquat cases. On June 18 in California, a notice of settlement was announced. This is for 16 parties in multiple cases who agreed to a settlement.
