Revealed: The secret push to bury a weedkiller’s link to Parkinson’s disease

 

Paraquat is not in Roundup, whose active ingredient is glyphosate, which has been linked to cases of non-Hodgkin's lymphoma. Paraqua is sold under the brand name Gramoxone

The global chemical giant Syngenta has sought to secretly influence scientific research regarding links between its top-selling weedkiller and Parkinson’s, internal corporate documents show.

While numerous independent researchers have determined that the weedkiller, paraquat, can cause neurological changes that are hallmarks of Parkinson’s, Syngenta has always maintained that the evidence linking paraquat to Parkinson’s disease is “fragmentary” and “inconclusive”.

But the scientific record they point to as proof of paraquat’s safety is the same one that Syngenta officials, scientists and lawyers in the US and the UK have worked over decades to create and at times, covertly manipulate, according to the trove of internal Syngenta files reviewed by the Guardian and the New Lede.

Syngenta’s decision to involve lawyers in the editing of its scientific reports and other communications in ways that downplayed concerning findings potentially related to public health is unacceptable, said Wendy Wagner, a law professor at the University of Texas who has served on several National Academies of Science committees. “Clearly the lawyers are involved in order to limit liability,” she said.

“It happens regularly in cases where a corporation’s internal research puts it at a high risk of expensive lawsuits. Regrettably, this kind of effective legal ghostwriting of scientific reports happens far too often in the chemical industry. Scientifically it doesn’t seem acceptable,” Wagner said.
