[Carey Gillam's] second recent article in the Guardian says that the herbicide formulation Roundup is more toxic to human cells than glyphosate alone. This revelation has been published many times before in actual journals, so this is not new information, just time to stoke the fear fire a bit more.
One of the best papers to illustrate the cytotoxic properties of the surfactants comes from Dr. Fiona Young's group. She shows that glyphosate has no effect on cells as an endocrine disruptor, and complete formulations become cytotoxic because of the surfactants. I wrote about it here, and did a podcast with her discussing the work and activist distortions here.
This is how Gillam continues her deception, spinning a known finding (detergents kill cells in petri dishes at certain concentrations) to imply some sort of risk to humans when none is observed.
Of course, Gillam and the Guardian don't check with scientists. They have their story of deadly toxicity and they are sticking to it. After all, it is not about science or truth. To them it is about advancing an agenda, selling a book, and promoting a bogus story that can instill fear about food and farming.
