One of my gardeners told me that in the good old days glyphosate salesmen used to drink a glass to prove it was safe.
Have you also been provided survival rates?
One notices that little is said of the saleswomen.
"Four cases of self-poisoning with 'Roundup' herbicide are described, one of them fatal. One of the survivors had a protracted hospital stay and considerable clinical and laboratory detail is presented. Serious self-poisoning is associated with massive gastrointestinal fluid loss and renal failure. The management of such cases and the role of surfactant toxicity are discussed." https://www.ncbi.nlm.nih.gov/pubmed/1675099
"Ingestion of >85 mL of the concentrated formulation is likely to cause significant toxicity in adults." https://www.ncbi.nlm.nih.gov/pubmed/15862083
I do not think stylish saleswomen drink it, but possibly spray it on their legs? to prove effective weed-hair removal?
"We argue that the practice of “ripening” sugar cane with glyphosate may explain the recent surge in kidney failure among agricultural workers in Central America. We conclude with a plea to governments to reconsider policies regarding the safety of glyphosate residues in foods." Glyphosate, pathways to modern diseases II: Celiac sprue and gluten intolerance
