Another study has chronicled the side effects of glyphosate exposure. In this study glyphosate residues in urine was tested in a wide range of mammals including hares, rabbits and humans.
The application and ingestion of glyphosate causes it to interfere with biochemical pathways including the cytochrome P450 enzymes which include numerous proteins able to metabolize xenobiotics. This can also disrupt and destroy the function of gut bacteria, vital to optimal human health. Several research studies have linked gastrointestinal disorders, obesity, diabetes, heart disease, depression, autism, infertility, cancer and Alzheimer’s disease to a diet that contains glyphosate either as as an applied herbicide pesticide residue or as a result of genetic modification to create plant resistance to glyphosate. Glyphosate shows both cytoxoic, genotoxic, and neurotoxic effects and has been linked to an increase presence of neurological diseases in areas of herbicide application such as Parkinson’s disease.
The results of this study correlated significantly to the amount of glyphosate exposure. Glyphosate urine excretion in German dairy cows was significantly lower than Danish cows. Cows kept in genetically modified free area had significantly lower glyphosate concentrations in urine than conventional husbandry cows. Also glyphosate was detected in different organs of slaughtered cows as intestine, liver, muscles, spleen and kidney. Fattening rabbits showed significantly higher glyphosate residues in urine than hares.
In humans, high glyphosate was linked a normal non organic diet and chronically ill humans showed significantly higher glyphosate residues in their urine than the healthy population. The presence of glyphosate in humans was reported in a previous study by monitoring 48 farmers, their spouses and 79 children (4-18 years) for glyphosate in urine the day before, as well as 1 and 3 days after glyphosate application.
The excretion of glyphosate in urine is not limited to farmers but to anyone who is exposed to the herbicide in various forms.
The researchers suggest that there is an enormous human public health risk associated with glyphosate and recommend further investigation and stringent regulation for glyphosate use and application.
