Independent experts find glyphosate unlikely to pose human carcinogenic risk

At Monsanto, we’re fully confident in the safety profile of our products. Our confidence is based on rigorous internal safety assessments in addition to safety assessments by regulatory authorities, independent researchers and other experts around the world. On 28 September a new peer-reviewed study reviewing the total scientific evidence of the herbicide glyphosate concluded that it is unlikely to pose a carcinogenic risk to humans.

In July 2015, Monsanto retained a scientific consultant to convene an expert panel to review the International Agency for Research on Cancer (IARC) monograph on glyphosate once it published. The charge to the experts was to take a thorough look at the data in the monograph, assess the scope of the research included or excluded, and publish their conclusions to allow for external review. The panel’s peer-reviewed findings recently were published in the journal Critical Reviews in Toxicology and are available in the paper: A review of the carcinogenic potential of glyphosate by four independent expert panels and comparison to the IARC assessment.

The experts that make up the panel include medical doctors, cancer experts and individuals who hold doctoral and other advanced degrees and who are experts in public health. The experts have spent their careers as researchers at major universities and medical schools, at research institutions and as consultants.

These findings by the panel come at an important time, after so much unnecessary confusion and concern has been caused by IARC’s classification of glyphosate. The panel’s findings are consistent with the conclusions of regulatory authorities around the world. In fact, since IARC classified glyphosate, regulatory authorities in the United States, Europe, Canada, Japan, New Zealand and Australia have publicly reaffirmed that glyphosate does not cause cancer. Just last week, the Environmental Protection Agency (EPA) announced their conclusion that glyphosate should be classified as “not likely to be carcinogenic to humans.” Additionally, in May 2016, the Joint FAO/WHO Meeting on Pesticide Residues (JMPR) concluded that “glyphosate is unlikely to pose a carcinogenic risk to humans from exposure through the diet.”
