The lowest dose of glyphosate used in this rat study was 0.5 mg/kg of body weight per day. Evidence I could find suggests average exposure in people is around 0.0001 mg/kg of body weight per day. That is 5,000 times lower than the lowest dose given to the rats.https://twitter.com/timspector/status/1209077386584698880 …

I haven't read the study yet, I just thought that was a point bearing in mind. 0.5 mg/kg of bw/day is a max safe level determined by EFSA. It may need to be lowered but it is a long way from any residues in food.

Data from the European Food Safety Authority can be found here. Hopefully my maths is correct. "Conclusion on the peer review of the pesticide risk assessment of the active substance glyphosate" https://www.efsa.europa.eu/en/efsajournal/pub/4302 …pic.twitter.com/OVB1tizmxt

It is common for animal studies to use maximum permitted amounts as their lowest dose. Rather than using the amounts humans typically consume, which probably wouldn't produce any results.

Replying to @MatthewJDalby
Most of these studies look at doses for those spraying glyphosate, which causes doses many thousands of times higher than normal people eating food, but then of course are used as evidence for normal people

To be clear, safety for farmers is of course important, but the extrapolation to the general public is dumb
