In a March 2015 review of five agents—four insecticides and glyphosate—IARC labeled the weedkiller as “probably carcinogenic in humans,” based on limited evidence in humans for non-Hodgkin lymphoma, and “sufficient evidence” in animals.

IARC conducted the review via its Monographs Programme, which is designed to identify environmental factors that can increase the risk of cancer. The program’s evaluations are watched by health agencies worldwide.

IARC’s conclusions on glyphosate, made by a working group of 17 scientists from 11 countries, ran counter to guidelines of the U.S. Environmental Protection Agency and the European Food Safety Authority. EPA said glyphosate has “low toxicity to humans,” and an EFSA study in November 2015 found glyphosate “unlikely to be carcinogenic.”

The IARC working group was chaired by Aaron Blair, a retired NCI epidemiologist.
