Glyphosate is the active ingredient in many commercially available herbicide products, including Roundup. Glyphosate is a chemical compound that has been registered for use as a herbicide with the EPA since 1974. In a letter published by the Chronicle Oct. 21, William Collins, referring to the herbicide (glyphosate), unequivocally states, “It causes cancer and other maladies.” What other maladies is, of course, unclear. Mr. Collins’ presumptive evidence: “... Monsanto ... is paying billions ... in damages to those who have been exposed to it.” By the way, a California judge already downsized the finding against Bayer (Monsanto’s owner) from billions to $250 million. And not a penny has yet been paid to any litigant.
Well, what does the science say about glyphosate as a human carcinogen? On Sept. 12, 2016, the Obama administration’s EPA (not Trump’s) published Glyphosate Issue Paper: Evaluation of Carcinogenic Potential. On page 140, “An extensive database exists for evaluating the carcinogenic potential of glyphosate, including 23 epidemiological studies, 15 animal carcinogenicity studies, and nearly 90 genotoxicity studies for the active ingredient glyphosate. ... studies were evaluated for quality and ... analyzed ... within each line of evidence.” Then, page 141, “For cancer descriptors, the available data and weight-of-evidence clearly do not support the descriptors carcinogenic to humans, likely to be carcinogenic to humans, or inadequate information to assess carcinogenic potential. For the suggestive evidence of carcinogenic potential descriptor, considerations could be looked at in isolation; however, following a thorough integrative weight-of-evidence evaluation of the available data ... would not support this cancer descriptor. The strongest support is for not likely to be carcinogenic to humans at doses relevant to human health risk assessment.”
In early 2018, Slate.com published a comprehensive analysis, easily understandable by laymen, of the on-going controversy re glyphosate, the European Union, and California regulators. The article clearly concludes, “... as the facts stand today, there is no indication that glyphosate raises the risk of cancer.”
Lawyers shilling on television for lucrative civil-suit business notwithstanding, there is no rigorous scientific evidence that glyphosate causes cancer in humans.
Next, Mr. Collins segues into blaming Trump for poisoning the streams “aka your water supply.” He then poses the left’s commonly employed rhetorical question when attempting to scare or shame anyone who disagrees with their political agenda, “How many of us is this going to kill?” Probably as many as have died from using Roundup.
