A group of fourteen experts, including ENSSER member Michael Antoniou and CRIIGEN[i] member Robin Mesnage, warns that current safety assessments of glyphosate based herbicides (GBHs) as well as their maximum daily intake limits are based on outdated science. Also, exposure levels have risen because drinking water, rain and air, especially in agricultural regions, but also foods, are increasingly contaminated. Moreover, glyphosate turns out to be more persistent in water and soil than previously recognized.

In a new peer-reviewed paper in the journal Environmental Health, the experts list their concerns, distinguishing between certainties, confident estimations, model-based predictions, unconfirmed presumptions based on existing data and relevant uncertainties in current safety assessments.
