Science Journal Retracts Study On Safety of Monsanto's Roundup
9 décembre 2025 à 13:00
An anonymous reader quotes a report from the Guardian: The journal Regulatory Toxicology and Pharmacology has formally retracted a sweeping scientific paper published in 2000 that became a key defense for Monsanto's claim that Roundup herbicide and its active ingredient glyphosate don't cause cancer. Martin van den Berg, the journal's editor in chief, said in a note accompanying the retraction that he had taken the step because of "serious ethical concerns regarding the independence and accountability of the authors of this article and the academic integrity of the carcinogenicity studies presented."
The paper, titled Safety Evaluation and Risk Assessment of the Herbicide Roundup and Its Active Ingredient, Glyphosate, for Humans, concluded that Monsanto's glyphosate-based weed killers posed no health risks to humans -- no cancer risks, no reproductive risks, no adverse effects on development of endocrine systems in people or animals. Regulators around the world have cited the paper as evidence of the safety of glyphosate herbicides, including the Environmental Protection Agency (EPA) in this assessment (PDF). [...]
In explaining the decision to retract the 25-year-old research paper, Van den Berg wrote: "Concerns were raised regarding the authorship of this paper, validity of the research findings in the context of misrepresentation of the contributions by the authors and the study sponsor and potential conflicts of interest of the authors." He noted that the paper's conclusions regarding the carcinogenicity of glyphosate were solely based on unpublished studies from Monsanto, ignoring other outside, published research. "The retraction of this study is a long time coming," said Brent Wisner, one of the lead lawyers in the Roundup litigation and a key player in getting the internal documents revealed to the public. Wisner said the study was the "quintessential example of how companies like Monsanto could fundamentally undermine the peer-review process through ghostwriting, cherrypicking unpublished studies, and biased interpretations."
"This garbage ghostwritten study finally got the fate it deserved,â Wisner added. "Hopefully, journals will now be more vigilant in protecting the impartiality of science on which so many people depend."
