The U.N.’s Food and Agriculture Organization (FAO) and World Health Organization (WHO) said glyphosate is “unlikely to pose a carcinogenic risk to humans” through dietary exposure in May 2016. Before the FAO and WHO report in 2016, WHO’s International Agency for Research on Cancer (IARC) issued a statement in March 2015 that classified glyphosate as “probably carcinogenic to humans.” WHO and IARC also noted there was limited evidence of glyphosate’s carcinogenicity in humans for non-Hodgkin lymphoma.
An epidemiologic review of studies on glyphosate that appeared in the Regulatory Toxicology and Pharmacology Journal found no evidence of “a causal relationship between any disease and exposure to glyphosate.”
