The vast majority ‒ 85 percent ‒ of tampons, cotton and sanitary products tested in a new Argentinian study contained glyphosate, the key ingredient in Monsanto’s Roundup herbicide, ruled a likely carcinogen by the World Health Organization.
Meanwhile, 62 percent of the samples tested positive for AMPA, glyphosate’s metabolite, according to the study, which was conducted by researchers at the Socio-Environmental Interaction Space (EMISA) of the University of La Plata in Argentina.
All of the raw and sterile cotton gauze analyzed in the study showed evidence of glyphosate, said Dr. Damian Marino, the study’s head researcher.
