Given its widespread, increasing use, it's not surprising that the chemical has received a ton of scrutiny. But based on all available evidence the EPA, the United Nations, and the European Food Safety Authority were able to come to a different conclusion than IARC—for few reasons. The first is that the IARC tends to be a bit more conservative in its assessments than the other agencies. Critics say that their assessment focused on toxicity at any dosage as opposed to the doses we'd likely encounter, either as people who eat foods sprayed with glyphosate or as farm workers. And secondly, the various agencies actually looked at different things in order to make their assesments. The European Food Safety Authority, for example, only looked at the effect of glyphosate, while the IARC included studies that examined the effects of consumer products containing glyphosate. It's completely possible that some consumer formulations of glyphosate herbicides contain harmful compounds, but it's completely possible that those harmful compounds are not the glyphosate itself.
