By Dr. Mercola In March 2015, the International Agency for Research on Cancer (IARC), which is the research arm of the World Health Organization (WHO), determined glyphosate, the active ingredient in Monsanto’s Roundup herbicide, to be a “probable carcinogen” (Class 2A). This determination was based on evidence showing the popular weed killer can cause non-Hodgkin’s lymphoma and lung cancer in humans, along with “convincing evidence” it can also cause cancer in animals. Monsanto has maintained that the classification as a carcinogen is wrong and continues to tout glyphosate (and Roundup) as one of the safest pesticides on the planet. The U.S. Environmental Protection Agency (EPA), meanwhile, has yet to take an official position regarding the virtually unchecked use of this poison on U.S. soil. The EPA postponed — at the behest of the industry — a series of public meetings it intended to hold earlier this year to discuss glyphosate research, particularly that linking it to cancer.
