Dr. Anthony Samsel was recently interviewed by Tony Mitra, where he discussed certain documents he has in his possession from the Environmental Protection Agency (EPA) that allegedly show Monsanto knew about research connecting glyphosate to cancer since the 1970s. Part 1 of the interview can be found here.
In this follow-up interview, Dr. Samsel discusses how the rat chow used in the laboratory feeds he analyzed were all contaminated with glyphosate. This is significant, as it means standard rat chow used in scientific studies have probably been contaminated since they started using GMO feeds that had been sprayed with glyphosate.
Dr. Samsel says that this is very problematic for the scientific community, because glyphosate is a contaminate, and should not be present in the feed of control animals used in scientific studies. He mentioned a recent folic acid study that reportedly showed a link between folic acid and mammary tumors, which he states is very contentious, and he points out that the animal chow consumed by the lab rats would have certainly been contaminated with glyphosate, which is now linked to cancer. The Purina lab chows are made from conventional corn, soy, and other GMO ingredients sprayed with glyphosate.
