When reading this, bear in mind two things. First, Monsanto, along with Dow, manufactured Agent Orange for the US Defense Department during the American War in Viet Nam. That herbicide cocktail is now "presumed" by the Department of Veterans Affairs to cause 15 different life threatening conditions. Second, government documents released under freedom of information requests in recent years record internal discussions that took place as early as 1960 between and among DoD officials and Dow employees regarding the known risks to mammals (notably humans) arising from exposure to Agent Orange. We might assume, but I cannot state with absolute certainty, that Monsanto knew this at the time, as well. They certainly knew subsequently.
In what is being described as the first ever and most comprehensive study of the effects of genetically modified foods on mammalian health, researchers have linked organ damage with consumption of Monsanto's GM maize.
