Glyphosate manufactured by Monsanto is used in a variety of way. GMOS are genetically engineered to be resistant to the herbicide and the chemical is sprayed to combat the spread of weeds.
The studies confirm that the use of glyphosate modifies the environment and stresses the living microorganisms. One study cites the increase of Clostridium botulinum associated disease in cattle over a 10-15 year period in Germany. Normal intestinal microflora acts as a critical element in preventing intestinal colonisation by C. botulinum and are directly and harmfully impacted by the ingestion of strong biocides like glyphosate.
Another study presented results suggesting that the highly pathogenic bacteria as Salmonella Entritidis, Salmonella Gallinarum, Salmonella Typhimurium, Clostridium perfringens and Clostridium botulinum are highly resistant to glyphosate. However, most of beneficial bacteria as Enterococcus faecalis, Enterococcus faecium, Bacillus badius, Bifidobacterium adolescentis and Lactobacillus spp. were found to be moderate to highly susceptible disturbing the normal gut bacterial community. Also, the toxicity of glyphosate to the most prevalent Enterococcus spp. could be a significant predisposing factor that is associated with the increase in C. botulinum-mediated diseases by suppressing the antagonistic effect of these bacteria on clostridia.
The impact of herbicide products is not limited to cattle but also affects human beings who unwittingly ingest genetically modified organisms that have been genetically engineered to be resistant to Roundup, supporting the concept of mandatory product labeling.
