There are no ‘glyphosate soaked’ tampons and they aren’t causing cancer

The GLP aggregated and excerpted this blog/article to reflect the diversity of news, opinion and analysis. 

There’s posts circulating around reporting that Dr. Damian Marino, a researcher from Argentina, claims that 85% of tampons he tested contain “cancer-causing glyphosate” and “62 percent also tested positive for AMPA, the environmental metabolite.” This data was presented at the “3rd National Congress of Peoples” (another website claims this was presented at the “Third National Congress of Doctors of Fumigated Peoples”). Dr. Marino is at the University of La Plata.

I have some issues.

The first is Dr. Marino hasn’t published this data and I can’t find a syllabus from a scientific conference using the search term “3rd National Congress of Peoples” or the “3rd National Congress of Fumigates Peoples.” I can only find a video of his talk in Spanish (see below).


Looking into the matter further the link provided (via Google translate) isn’t an article but appears to be some kind of press release.

Obviously, when researchers make claims about contaminants in products (or about anything) we need to make sure their methodology is sound and their conclusions accurate. Without the methods, data, and their statistical analysis that isn’t possible. Someone saying they did a study doesn’t count. However, digging a bit further it appears that Dr. Marino has published in this area in peer-reviewed journals so I will assume that his methodology is sound.
