US Congress members call on EPA to ban paraquat, citing risk of Parkinson’s and other diseases

By Carey Gillam

More than 50 US lawmakers are calling on the Environmental Protection Agency (EPA) to join dozens of other nations in banning a widely used weed killer linked to Parkinson’s disease and other health dangers.

In an Oct 31 letter to the agency, seven US senators said that paraquat, a weed killer commonly applied on US farms, was a “highly toxic pesticide whose continued use cannot be justified given its harms to farmworkers and rural communities.” The call for a ban from the senators came after 47 members of the US House of Representatives sent a similar letter to the EPA calling for a ban earlier in October.

The lawmakers cite scientific links between paraquat use and development of Parkinson’s and other “life threatening diseases” as well as “grave impacts on the environment”. The lawmakers note that approximately 70 countries have banned paraquat.

“Numerous studies” have found that paraquat causes “serious health risks for workers who use the substance as well as the surrounding communities,” the lawmakers wrote. “These health risks include a higher risk of Parkinson’s disease, with some studies finding a 64% increase in the likelihood of developing Parkinson’s, non-Hodgkin’s Lymphoma, thyroid cancer, and other thyroid issues.”

Sen. Cory Booker, organizer of the Senate letter, said the risks of paraquat exposure are “well documented” and that it is “irresponsible” for the EPA to continue to allow its use. “I hope the EPA will follow the science and ban paraquat,” Booker said.

The congressional letters add to mounting pressure on the EPA to remove paraquat from the market.

Paraquat ties to Parkinson’s disease featured on Al Jazeera news

Evidence tying the popular weed killer paraquat to Parkinson’s disease is featured this week in an online news segment that includes fresh details about corporate influence over US regulators and suppression of scientific research.

Al Jazeera’s investigative show Fault Lines highlights the reporting of The New Lede (TNL) and the thousands of internal corporate documents obtained by TNL that reveal decades of efforts by Syngenta, paraquat’s longtime manufacturer, to conceal evidence of how chronic exposure to paraquat can cause Parkinson’s disease.

Last month, the “Paraquat Papers” reporting by The New Lede was also the focus of an ABC News Nightline segment.

The New Lede, in collaboration with The Guardian, first revealed a trove of internal Syngenta documents in October 2022 and followed up in subsequent stories, exposing years of corporate efforts to cover up evidence that paraquat can cause Parkinson’s disease. The documents obtained by The New Lede additionally showed evidence of efforts to manipulate and influence the Environmental Protection Agency (EPA) and published scientific literature. The documents also show how the company worked to mislead the public about paraquat dangers, among other secret strategies.

The Fault Lines piece adds to TNL reporting with several on-camera interviews.

Guest column: Syngenta’s paraquat product kills weeds, but also people

By Jon Heylings

From 1986 until 2008, I worked as the lead scientist on a project aimed at creating a “safer” paraquat-based weed killing product for what was then known as the ICI Central Toxicology Laboratory, which became part of Syngenta AG in 2000.
