The US Environmental Protection Agency (EPA) has taken the opposite stance (than the WHO), classifying glyphosate as not likely to be carcinogenic. But last month a federal appeals court issued an opinion vacating the agency’s safety determination and ordering the agency to give “further consideration” to evidence of glyphosate risks.
Two meta-analyses of the association between glyphosate and cancer published after the (2015) IARC review have examined more recently published epidemiologic data. Both studies confirm the association between glyphosate and non- Hodgkin lymphoma. Researchers specifically found a statisti- cally significant, 40% to 41% increase in incidence of non- Hodgkin lymphoma in persons exposed to glyphosate-based herbicides.47,48 Similarly, a recently published pooled analy- sis of cohort studies of farmers exposed to glyphosate-based herbicides reported a statistically significant, 36% increase in incidence (95% confidence interval [CI], 1.00–1.85) of dif- fuse large B-cell lymphoma.49
