Glyphosate, your hormones, cancer, and why all the previous science was wrong but also right with Ian Shaw.

I speak to Professor Ian Shaw an international expert on food safety. We talk about glyphosate as an environmental estrogen, estrogen mimicry, ideas on non-genotoxic carcinogenicity and how former research was right and then turned out to be completely wrong, long term inflammatory effects and possible environmental impact of glyphosate through avenues that were not previously considered. Shaw is the former chair of the UK Pesticide Residues Committee and working as the National Food Safety Programme Manager at the Institute of Environmental Science and Research (ESR), based in Christchurch. He specialises in chemical residues in food and the environment and their human health effects and leads the Toxicology Research Group at the University of Canterbury.
