MONSANTO KNEW OF GLYPHOSATE

GM-Free Cymru Special Report

8th April 2015

According to evidence unearthed from the archives of the EPA (Environmental Protection Agency) in the United States, it has been established that Monsanto was fully aware of the potential of glyphosate to cause cancer in mammals as long ago as 1981.

Recently the WHO’s International Agency for Research on Cancer (IARC) issued a statement in which glyphosate (the main component of Roundup herbicide) was classified as “probably carcinogenic” to humans and as “sufficiently demonstrated” for genotoxicity in animals (1). This announcement of a change to toxicity class 2A was given vast coverage in the global media, causing Monsanto to move immediately into damage limitation mode. The corporation demanded the retraction of the report, although it has not yet been published! Predictably, there was more fury from the industry-led Glyphosate Task Force (2). This Task Force also sponsored a “rebuttal” review article (3) from a team of writers with strong links with the biotechnology industry; but because of the clear bias demonstrated in this paper (which suggests that glyphosate has no carcinogenic potential in humans) it is best ignored until it has been carefully scrutinized by independent researchers (4).

With Monsanto continuing to protest that glyphosate and Roundup are effectively harmless (5) if used according to instructions, in spite of accumulating evidence to the contrary, we undertook a search through Environmental Protection Agency (EPA) records with a view to finding out what was known about glyphosate at the time of its initial registration. This followed up earlier investigations by Sustainable Pulse which highlighted a sudden change in the EPA view on toxicity in 1991. What was discovered was very revealing. There were many animal experiments (using rats, mice and dogs) designed to test the acute and chronic toxicity of glyphosate in the period 1978-1986, conducted by laboratories such as Bio/dynamics Inc for Monsanto and submitted for EPA consideration. Two of these reports relate to a three-generation reproduction study in rats (6) (7), and another is called “A Lifetime Feeding Study Of Glyphosate In Rats” (8); but like all the other older studies they were and still are treated as Trade Secrets and cannot be freely accessed for independent scrutiny. That in itself is suggestive that the studies contain data which Monsanto still does not wish to be examined by experts in the toxicology field. It is also deeply worrying that EPA acceded to the routine Monsanto requests for secrecy on the flimsiest of pretexts.
