Glyphosate is the world’s most widely produced herbicide and is the primary toxic chemical in Roundup™, as well as in many other herbicides. In addition, it is a broad-spectrum herbicide that is used in more than 700 different products from agriculture and forestry to home use.
Recent studies have discovered glyphosate exposure to be a cause of many chronic health problems. It can enter the body by direct absorption through the skin, by eating foods treated with glyphosate, or by drinking water contaminated with glyphosate. A recent study stated that a coherent body of evidence indicates that glyphosate could be toxic below the regulatory lowest observed adverse effect level for chronic toxic effects, and that it has teratogenic, tumorigenic and hepatorenal effects that can be explained by endocrine disruption and oxidative stress, causing metabolic alterations, depending on dose and exposure time. The World Health Organization International Agency for Research on Cancer published a summary in March 2015 that classified glyphosate as a probable carcinogen in humans. Possible cancers linked to glyphosate exposure include non-Hodgkin lymphoma, renal tubule carcinoma, pancreatic islet-cell adenoma, and skin tumors. Studies have also indicated that glyphosate disrupts the microbiome in the intestine, causing a decrease in the ratio of beneficial to harmful bacteria. Thus, highly pathogenic bacteria such as Salmonella entritidis, Salmonella gallinarum, Salmonella typhimurium, Clostridium perfringens, and Clostridium botulinum are highly resistant to glyphosate but most beneficial bacteria such as Enterococcus faecalis, Enterococcus faecium, Bacillus badius, Bifidobacterium adolescentis, and Lactobacillus spp. were found to be moderately to highly susceptible. The relationship between the microbiome of the intestine and overall human health is still unclear, but current research indicates that disruption of the microbiome could cause diseases such as metabolic disorder, diabetes, depression, autism, cardiovascular disease, and autoimmune disease.
High correlations exist between glyphosate usage and numerous chronic illnesses, including autism. A recent study on a set of triplets (two with autism and one with a suspected seizure disorder) and found that when their intake of glyphosate was decreased (switching to organic food), their symptoms improved. Other disease incidences with high correlations include hypertension, stroke, diabetes, obesity, lipoprotein metabolism disorder , Alzheimer’s, senile dementia, Parkinson’s, multiple sclerosis, inflammatory bowel disease, intestinal infections, end stage renal disease, acute kidney failure, cancers of the thyroid, liver, bladder, pancreas, kidney, and myeloid leukemia. Correlations are not causations, yet they raise concern over the use of a chemical to which all life on earth appears to be exposed.
