An IARC ruling that glyphosate was a probable human carcinogen served as the impetus for these suits. Of all the substances IARC has examined, they have only ever found ONE not to be a known, probable or possible human carcinogen.
Glyphosate was listed as a "probable", which includes (among many others) acrylamide (eg, from baking starches), emissions from high-temperature frying, glyphosate, red meat (consumption), styrene. The known carcinogen list includes ethanol in alcoholic beverages, diesel exhaust, aflatoxin, processed meat, solar radiation, vinyl chloride, welding fumes, wood dust, among many others. Many substances are listed by their chemical name, so it is difficult to know where exposure might occur (eg, cosmetics, processed foods, cleaning products, etc.).
Known and Probable Human Carcinogens
The ACSH is not the only group that has criticized the IARC designation process, and specifically its ruling on glyphosate; many of these are from academics with no known ties to the industry....which can't be said for all members of the IARC panel, some of whom had known conflicts because of ties to (what I will call) the protest industry.
It is especially worth noting that IARC only assesses whether, in their opinion, a substance has carcinogenic properties (ie, is a hazard); they do not assess exposure pathways, so haven't made any statement about the true risk of these substances...if you aren't exposed, then the hazard isn't realized.
In the court cases, I can't see how the high settlements are anything more than sympathetic juries attacking a vilified corporation. Some relevant questions: Is the hazard real? If so, how much responsibility do the plantiff's have for their own exposure to the hazard? What other exposures did they have to other known or probable carcinogens (eg, do they operate diesel vehicles, eat bread or meat, etc.)?
I wouldn't
drink or bathe in glyphosate, but I also don't go to extremes in self-protection when I use it, nor do I worry about residues in my food...something like aflatoxin is a much bigger risk, IMO.
