OUR QUESTION:If you're wondering why glyphosate herbicide is still legally present in your food and in GM animal feed when the World Health Organisation’s International Agency for Research on Cancer (IARC) has found it "probably carcinogenic to humans", some light was shed on this by the evidence heard during the 'Monsanto Tribunal' held in October 2016 (see below).
The IARC looked at experiments on mice fed glyphosate. In one life-time study, they saw significant increases in kidney tumours, and in another they saw increases in blood vessel cancer. They also noted increases in malignant lymphoma (blood cell cancer) in a further three mouse studies, but these were only mentioned, not included in the final report, because they were non-peer reviewed industry studies whose details couldn't be ascertained.
An IARC classification of 'probably carcinogenic' was unwelcome because it's only one short step away from "presumed carcinogen" which would, under EU law, trigger an automatic ban unless exposure levels were "negligible" (and this doesn't mean 'below permitted levels').
