'Web of Deception': Syngenta Docs Show Company Tried to Hide Pesticide's Link to Parkinson's
"It looks like the paraquat maker has adopted nearly every strategy we outlined in our book about bending science," said one author and former EPA legal adviser.
Jun 02, 2023
Internal documents published Friday by The Guardian and The New Lede shed new light on how multinational chemical giant Syngenta worked to conceal the link between its popular pesticide paraquat and Parkinson's disease.
According to the internal documents, Syngenta sought to "create an international scientific consensus against the hypothesis that paraquat is a risk factor for Parkinson's disease," in part by launching what company officials called a "SWAT team" to counter research that could threaten the corporation's "freedom to sell" the pesticide.
"It looks like the paraquat maker has adopted nearly every strategy we outlined in our book about bending science," Thomas McGarity, a former U.S. Environmental Protection Agency legal adviser and co-author of the 2008 book Bending Science: How Special Interests Corrupt Public Health Research, told The Guardian.
"Science matters. We have to be able to depend on science," McGarity added. "When it is perverted, when it is manipulated, then we get bad results. And one result is that pesticides that cause terrible things like Parkinson's remain on the market."
While a 2006 study found that rats administered paraquat exhibited neural degeneration similar to Parkinson's, a definitive link between paraquat and Parkinson's disease was discovered in 2011, when National Institutes of Health researchers concluded that the brain disorder is "positively associated" with the pesticide. A 2013 paper published in the peer-reviewed journal Neurology found that exposure to paraquat roughly doubled the risk of developing Parkinson's. In 2020, four of the world's leading neurologists published a book citing paraquat as a cause of Parkinson's.
More than 50 countries have banned paraquat, including Brazil, China, and the United Kingdom. The European Union has also banned the pesticide.
Syngenta argues that the evidence showing paraquat causes Parkinson's is "fragmentary and insufficient to establish" a link between the pesticide and the brain disorder.
"Recent thorough reviews performed by the most advanced and science-based regulatory authorities, including the United States and Australia, continue to support the view that paraquat is safe," the company told The Guardian for an October 2022 article showing internal Syngenta documents confirmed that corporate officials worried about the pesticide's link to Parkinson's.
However, as The Guardian reports in the new article:
The scientific record [Syngenta points] to as proof of paraquat's safety is the same one that Syngenta officials, scientists, and lawyers in the U.S. and the U.K. have worked over decades to create and at times, covertly manipulate...
The files reveal an array of tactics, including enlisting a prominent U.K. scientist and other outside researchers who authored scientific literature that did not disclose any involvement with Syngenta; misleading regulators about the existence of unfavorable research conducted by its own scientists; and engaging lawyers to review and suggest edits for scientific reports in ways that downplayed worrisome findings.
McGarity also said that when he worked at the EPA, pesticide lobbyists were known as "hall crawlers" for their incessant efforts to influence government officials.
Additionally, a revolving door between the chemical industry and government at all levels, from EPA bureaucrats all the way up to the Supreme Court—Justice Clarence Thomas is a former Monsanto attorney who refused to recuse himself from a case involving his former employer—helps corporations conceal the harms caused by their products.
In 2021, a coalition of groups sued the EPA over its decision to renew its approval of paraquat.
The new documents were published amid a raft of over 2,000 product liability lawsuits filed by farmers and others against Syngenta and Chevron, paraquat's former distributor. The first federal bellwether paraquat trial is set to begin in October.
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission has always been simple: To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It's never been this bad out there. And it's never been this hard to keep us going. At the very moment Common Dreams is most needed, the threats we face are intensifying. We need your support now more than ever. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Will you donate now to make sure Common Dreams not only survives but thrives? —Craig Brown, Co-founder |
