A key study linking Monsanto's Roundup herbicide to cancer has been formally retracted by a prestigious scientific journal due to "serious ethical concerns" about its validity and authorship. The Regulatory Toxicology and Pharmacology journal removed the 2000 paper, titled "Safety Evaluation and Risk Assessment of the Herbicide Roundup and Its Active Ingredient Glyphosate for Humans," from its database after an investigation raised questions about the independence of its authors.
The original study concluded that glyphosate-based weed killers posed no health risks to humans, which has been cited by regulators around the world as evidence of their safety. However, internal company documents obtained through litigation have revealed that Monsanto significantly influenced the paper's development and presentation. These documents show how company officials celebrated the publication of the paper and praised employees involved in its creation.
In one email, a Monsanto official described the toll on multiple employees who worked on developing "independent" research papers, highlighting the influence of corporate interests on academic integrity. The same document also revealed that Roundup logo polo shirts could be given to researchers as a "token of appreciation for a job well done."
The retractions come after decades of conflict over glyphosate's safety and comes at a time when the Trump administration is urging the US Supreme Court to limit thousands of lawsuits claiming Roundup causes cancer. Bayer, which acquired Monsanto in 2018, released a statement saying that its involvement was adequately noted in the acknowledgments section of the paper.
The EPA has stated that it "has never relied on this specific article" in developing regulatory conclusions on glyphosate and is currently conducting an updated human health risk assessment using "gold standard science." The agency said that retraction is a long time coming, highlighting concerns about ghostwriting, cherrypicking unpublished studies, and biased interpretations.
