ST. LOUIS (Dec. 8, 2015) – In July, Monsanto retained Intertek Scientific & Regulatory Consultancy to convene an expert panel to review the International Agency for Research on Cancer (IARC) monograph on glyphosate. The international experts recently completed their evaluation of the IARC monograph on glyphosate and presented their findings during a poster session at the annual meeting of the Society for Risk Assessment (SRA).

In a presentation abstract, the experts concluded, “None of the results from a very large database, using different methodologies, provides evidence of, or a potential mechanism for, human carcinogenesis.” The expert panel also found that the IARC animal bioassay and genotoxicity evaluations “suffered from significant weaknesses such as: selectivity in the choice of data reviewed, failure to use all relevant biologic information to evaluate relationship to treatment in animal bioassays, and failure to use weight-of-evidence (WOE) evaluations using all available data and appropriate weighting.” The full abstract is posted here.

The panel’s findings are consistent with the recent European Food Safety Authority’s (EFSA) conclusion that “glyphosate is unlikely to pose a carcinogenic hazard to humans”; the determination of the Canadian Pest Management Regulatory Agency in April that “the overall weight of evidence indicates that glyphosate is unlikely to pose a human cancer risk”; and a recent statement from the U.S. EPA that a set of 55 epidemiological studies “does not provide evidence to show that glyphosate causes cancer.”
