In secret internal Monsanto documents released on Tuesday by legal firms in the U.S. it was revealed how Monsanto led the attack on the International Agency for Research on Cancer (IARC), after the Agency announced that glyphosate, the active ingredient in Monsanto’s Roundup herbicide, is a probable human carcinogen in 2015.

The new revelations follow similar revelations in May, which showed how the same Monsanto manager, Dr. George Levinskas, who helped hide the carcinogenic potential of PCBs in the 1970s,  also influenced the U.S. Environmental Protection Agency (EPA) regarding the carcinogenic potential of glyphosate in the 1980s.

On Tuesday it was shown how Monsanto edited and wrote an ‘independent’ Expert Panel Manuscript to refute IARC’s findings. It was also revealed that Monsanto paid members of the ‘independent’ Expert Panel as consultants and also planned a press attack with a Forbes contributor on the IARC findings, even before they were published.

Amazingly the secret documents have shown that Monsanto went even further than just attacking IARC over their glyphosate decision. They decided to try and “invalidate relevance of IARC” so as to “prevent future bad IARC decisions on pesticides/GMOs” . Monsanto did this by using U.S. political influence to pressure the World Health Organization and others to try and control IARC.

Monsanto Executive William Heydens’ Edits and Comments on Expert Consultant Manuscript
No: MONGLY01000676, MONGLY01000680
Date: 2/8/2016 – 2/9/2016

Description
This document contains correspondence between Dr. William Heydens and Ashely Roberts regarding the Expert Panel Manuscript.  Dr. Heydens went “through the entire document and “indicated what I think should stay, what can go, and in a couple spots I did a little editing. I took a crack at adding a little text: on page 10 to address John’s comments about toxicologists’ use of Hill’s criteria … see what you think; it made sense to me, but I’m not sure if it will to others – please feel free to further modify and/or run by Cary.” at *1. The edited draft is also attached and challenged for confidentiality.
