Academic papers vindicating its Roundup herbicide were written with the help of its employees
EXCERPT: Monsanto’s editorial involvement appears “in direct opposition to their disclosure,” says Genna Reed, a science and policy analyst at the Union of Concerned Scientists’ Center for Science and Democracy. “It does seem pretty suspicious.”

* Academic papers vindicating its Roundup herbicide were written with the help of its employees
Monsanto Co. started an agricultural revolution with its “Roundup Ready” seeds, genetically modified to resist the effects of its blockbuster herbicide called Roundup. That ability to kill weeds while leaving desirable crops intact helped the company turn Roundup’s active ingredient, the chemical glyphosate, into one of the world’s most-used crop chemicals. When that heavy use raised health concerns, Monsanto noted that the herbicide’s safety had repeatedly been vetted by outsiders. But now there’s new evidence that Monsanto’s claims of rigorous scientific review are suspect.
Dozens of internal Monsanto emails, released on Aug. 1 by plaintiffs’ lawyers who are suing the company, reveal how Monsanto worked with an outside consulting firm to induce the scientific journal Critical Reviews in Toxicology to publish a purported “independent” review of Roundup’s health effects that appears to be anything but. The review, published along with four subpapers in a September 2016 special supplement, was aimed at rebutting the 2015 assessment by the International Agency for Research on Cancer (IARC) that glyphosate is a probable human carcinogen. That finding by the cancer-research arm of the World Health Organization led California last month to list glyphosate as a known human carcinogen. It has also spurred more than 1,000 lawsuits in state and federal courts by plaintiffs who claim they contracted non-Hodgkin lymphoma from Roundup exposure.
Monsanto disclosed that it paid Intertek Group Plc’s consulting unit to develop the review supplement, entitled “An Independent Review of the Carcinogenic Potential of Glyphosate.” But that was the extent of Monsanto’s involvement, the main article said. “The Expert Panelists were engaged by, and acted as consultants to, Intertek, and were not directly contacted by the Monsanto Company,” according to the review’s Declaration of Interest statement. “Neither any Monsanto company employees nor any attorneys reviewed any of the Expert Panel’s manuscripts prior to submission to the journal.”
Monsanto’s internal emails tell a different story. The correspondence shows the company’s chief of regulatory science, William Heydens, and other Monsanto scientists were heavily involved in organizing, reviewing, and editing drafts submitted by the outside experts. At one point, Heydens even vetoed explicit requests by some of the panelists to tone down what one of them wrote was the review’s “inflammatory” criticisms of IARC.
“An extensive revision of the summary article is necessary,” wrote that panelist, John Acquavella, an epidemiologist at Aarhus University in Denmark, in a February 2016 email attached to his suggested edits of the draft. Alarmed, Ashley Roberts, the coordinator of the glyphosate papers for Intertek, forwarded Acquavella’s note and edits to Heydens at Monsanto, with the warning: “Please take a look at the latest from the epi(demiology) group!!!!”
Heydens reedited Acquavella’s edits, arguing in six different notes in the draft’s margin that statements Acquavella had found inflammatory were not and should not be changed, despite the author’s requests. In the published article, Heydens’s edits prevailed. In an interview, Acquavella says that he was satisfied with the review’s final tone. According to an invoice he sent Monsanto, he billed the company $20,700 for a single month’s work on the review, which took nearly a year to complete.
Monsanto defends the review’s independence. Monsanto did only “cosmetic editing” of the Intertek papers and nothing “substantive” to alter panelists’ conclusions, says Scott Partridge, Monsanto’s vice president for global strategy. While the “choice of words” in the Declaration of Interest “was not ideal,” he says, “it didn’t change the science.”
In July 2016, the journal’s editor, Roger McClellan, emailed his final instructions to Roberts at Intertek on what the paper’s Acknowledgment and Declaration of Interest statements should include. “I want them to be as clear and transparent as possible,” he wrote. “At the end of the day I want the most aggressive critics of Monsanto, your organization and each of the authors to read them and say—Damn, they covered all the points we intended to raise.”
Specifically, McClellan told Roberts to make clear how the panelists were hired — “ie by Intertek,” McClellan wrote. “If you can say without consultation with Monsanto, that would be great. If there was any review of the reports by Monsanto or their legal representatives, that needs to be disclosed.”
Roberts forwarded McClellan’s emails, along with a more technical question, to Heydens, who responded, “Good grief.” The Declaration of Interest statement was rewritten per McClellan’s instructions, despite being untrue. There was no mention of the company’s participation in the editing.
Monsanto’s editorial involvement appears “in direct opposition to their disclosure,” says Genna Reed, a science and policy analyst at the Union of Concerned Scientists’ Center for Science and Democracy. “It does seem pretty suspicious.”
In response to questions, McClellan wrote in an email on Aug. 7 that he’d been unaware of the Monsanto documents and has forwarded the matter to the journal’s publisher, Taylor & Francis, in Abingdon, England. “These are serious accusations relative to scientific publishing canons and deserve very careful investigation,” he wrote. “I can assure you that Taylor and Francis, as the publisher, and I, as the Scientific Editor of Critical Reviews in Toxicology, will carefully investigate the matter and take appropriate action.” A Taylor & Francis spokeswoman says it has begun an investigation.
The Monsanto documents, more than 70 in all, were obtained through pretrial discovery and posted online by some of the plaintiffs’ lawyers, who claim Monsanto missed a 30-day window to object to their release. Monsanto says it was blindsided by the disclosures and has asked U.S. District Judge Vince Chhabria in San Francisco to order the documents pulled from the web and to punish the attorneys for violating confidentiality orders. Says Monsanto’s Partridge: “It’s unfortunate these lawyers are grandstanding at the expense of their clients’ interests.”
Other emails show that Monsanto’s lead toxicologist, Donna Farmer, was removed as a co-author of a 2011 study on glyphosate’s reproductive effects, but not before she made substantial changes and additions to the paper behind the scenes. The study, published in Taylor & Francis’s Journal of Toxicology and Environmental Health, served to counter findings that glyphosate hampers human reproduction and development. Partridge says Farmer’s contributions didn’t warrant authorship credit. While almost all of her revisions made it into the published paper, her name doesn’t even show up in the acknowledgments.
BOTTOM LINE - Monsanto has long noted that independent scientists have vouched for the safety of its Roundup herbicide. Court data show its employees edited some of those reviews.
