glyphosate tainted tampons and pads?

RT |  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.

In 2014, 96 percent of cotton produced in the United States was genetically modified, according to the US Department of Agriculture.

Transnational agrochemical giant Monsanto's Roundup herbicide, of which glyphosate is the main ingredient, is sprayed over genetically modified crops ‒ which Monsanto also produces ‒ that are engineered to be resistant to the powerful chemical. Used the world over, glyphosate, which Monsanto first developed in 1974, is a broad-spectrum herbicide used to kill weeds, especially annual broadleaf weeds and grasses known to compete with commercial crops. GMO seeds have caused use of glyphosate to increase immensely since the 1990s, according to US Geological Survey data.

In March, the International Agency for Research on Cancer (IARC), an arm of the World Health Organization, classified glyphosate as a "probable carcinogen," as opposed to its previous designation, a "possible carcinogen."
