Warning: New Study Finds Cancer-Causing Glyphosate in Most Tampon Samples

By On October 22, 2015



Ever since the chemical glyphosate, which is of course the main ingredient in Monsanto’s Roundup, was found by the World Health Organization to be a “probable human carcinogen,” more and more people have begun avoiding it in their food.

Of course, you can avoid glyphosate in your food by buying organic foods as much as possible, especially locally from a trusted farmer. But there’s one potentially dangerous source of glyphosate going into women’s bodies that most of them probably don’t even think about: their tampons, according to new research out of Argentina.

Most Tampons Test Positive for Glyphosate

According to a recent study out of the University of La Plata , 85 percent of all samples of tampons tested positive for glyphosate, and 62 percent also tested positive for AMPA, the environmental metabolite. The news comes according to Dr. Damian Marino, who shared his findings with the Telam agency.

In the case of cotton and gauze, that figure rose to one hundred percent according to Dr. Marino, who is one of the members of the Socio-Environmental Interaction Multidisciplinary Space (EMISA) UNLP who conducted the research, the article said.


Most tampons in the U.S. and many in Argentina are made from genetically engineered cotton.

Glyphosate is one of the most widely used herbicides in the world, but many municipalities, stores, and other areas have begun banning or restricting it since the WHO story came out. Cotton is especially saturated with glyphosate compared to other crops, and a large percentage of American cotton is also genetically modified to withstand large doses of glyphosate.

Considering the sensitive area in which tampons are typically applied, it comes as no surprise that the presentation of these findings drew quite a bit of attention when they were presented at the 3rd National Congress of Peoples last week.

“The result of this research is very serious. When you use cotton or gauze to heal wounds or personal use (hygienic), (people do so) thinking they are sterilized products, and results that are contaminated with a carcinogenic substance,” said pediatrician Vazquez Medardo Avila according to the above article.

“Most of the cotton production in the country is resistant transgenic glyphosate (and) is sprayed when the cocoon is open; glyphosate is then condensed and passes directly to the product,” Avila continued.

“The study has surprised us all because in fact our goal was to demonstrate the presence of these carcinogenic substances especially in food, and research at the University of La Plata opens a new door that we must continue,” added Avila Vazquez, president of the Congress.

Most tampon brands in Argentina are imported and include American brands like OB and Kotex. Samples were taken from local stores for the study.

Glyphosate is not just in food and personal care products, unfortunately. A July study also found glyphosate in 90% of sampled Buenos Aires residents from one particular neighborhood, even those who had no contact with glyphosate, which researchers are speculating has become ubiquitous in the area because of overuse on farmland. It is now coming down in surprising amounts in the rain, they said.

Time to Switch to Organic Tampons?



While organic tampons are not very commonplace in stores in the United States, it goes without saying that making the switch could be very beneficial for women’s health if you can find them.

An estimated 94 percent of the cotton in the U.S. is genetically modified according to the USDA, and likely contains a considerable amount of glyphosate as the Argentinian study just showed. That could make using everyday tampon brands much more harmful than most had thought. For more on the Agrentinian study’s findings, you can click on this link.
