Earlier this year, the World Health Organization (WHO) declared glyphosate, the main ingredient in Monsanto's best-selling Roundup herbicide, to be "probably carcinogenic." 

While a number of countries scrambled to ban the sale and importation of glyphosate-containing products, few thought to consider what other items should be removed from store shelves to protect consumers.

Because cotton is one of the top four GMO crops produced in the world and is heavily treated with pesticides, there is reason to be concerned about the safety of products it is used in. This suspicion was  confirmed recently in an Argentian study which found that the vast majority – 85% – of tampons, cotton, and sanitary products testedcontained glyphosate.

Reuters reports that 62% of the samples also tested positive for AMPA, glyphosate's metabolite. The study was conducted by researchers at the Socio-Environmental Interaction Space (EMISA) of the University of La Plata in Argentina.

According to Dr. Damian Marino, the study's head researcher, ALL of the raw and sterile cotton gauze analyzed in the study showed evidence of glyphosate. This is very concerning for a number of reasons.
