Science journal retracts study on safety of Monsanto’s Roundup: ‘serious ethical concerns’

AI Summary

long article 5 min

The journal *Regulatory Toxicology and Pharmacology* retracted a 2000 study that claimed Monsanto's Roundup herbicide and glyphosate were safe for humans. The retraction, issued by editor Martin van den Berg, cited "serious ethical concerns" regarding author independence and the integrity of carcinogenicity studies. The retracted paper, authored by Gary Williams, Robert Kroes and Ian Munro, had been used by regulators, including the EPA, to support the safety of glyphosate. Internal Monsanto documents revealed the company's influence on the paper, including Monsanto employees' involvement in its development, despite being presented as independent research. These documents surfaced during litigation related to cancer claims against Roundup, raising questions about the paper's validity and Monsanto's "Freedom to Operate" strategy.
