Global Glyphosate Herbicide Study Shows Adverse Health Effects on Children at "Safe" DoseGlyphosate-based herbicide caused adverse health effects in rats at a dose claimed to be safe by regulators, according to a new study. Glyphosate herbicides are used on the vast majority of all GM crops worldwide. The study used the US Environmental Protection Agency’s acceptable daily dietary exposure level of glyphosate – 1.75 mg per kg of bodyweight per day. The same concentration was given to the rats daily over a 3-month period. The study was focused on the newborn, infancy and adolescence phases of life. The results reveal that glyphosate-based herbicide (GBH) was able to alter certain important biological parameters, mainly relating to sexual development, genotoxicity, and the intestinal microbiome. The effects occurred at a dose deemed safe by regulators to ingest on a daily basis over a long-term period. In human-equivalent terms the dosing period corresponded to the period from the embryo stage to 18 years of age.
