The U.S. EPA classified glyphosate as Group E, evidence of non-carcinogenicity in humans. The U.S. EPA does not consider glyphosate to be a human carcinogen based on studies of laboratory animals that did not produce compelling evidence of carcinogenicity.
German Risk Agency “In conclusion of this re-evaluation process of the active substance glyphosate by BfR the available data do not show carcinogenic or mutagenic properties of glyphosate nor that glyphosate is toxic to fertility, reproduction or embryonal/fetal development in laboratory animals.
Australian Pesticides and Veterinary Medicines Authority “The APVMA currently has no data before it suggesting that glyphosate products registered in Australia and used according to label instructions present any unacceptable risks to human health, the environment and trade …”“The weight and strength of evidence shows that glyphosate is not genotoxic, carcinogenic or neurotoxic. “
World Health Organization International Programme on Chemical Safety “Animal studies show that glyphosate is not carcinogenic, mutagenic or teratogenic.”

A Potato a Day Keeps the Cholera AwayA Potato a Day Keeps the Cholera Away
Biologist are using genetic engineering to insert a new gene into potatoes. These gene causes the plants to produce a chemical, called a B-protein, that is a harmless part of cholera toxin, or poison. When children eat a certain amount of these genetically altered potatoes, they become vaccinated against cholera.

You could detect glyphosate at a few ng / m3 close to a cotton field when glyphosate had been recently applied
Glyphosate replaced other more toxic herbicides
