Monsanto’s GM Corn Damages Organs: A Comparison of the Effects of Three GM Corn Varieties on Mammalian Health

January 13th, 2010

Via: International Journal of Biological Sciences:

We present for the first time a comparative analysis of blood and organ system data from trials with rats fed three main commercialized genetically modified (GM) maize (NK 603, MON 810, MON 863), which are present in food and feed in the world. NK 603 has been modified to be tolerant to the broad spectrum herbicide Roundup and thus contains residues of this formulation. MON 810 and MON 863 are engineered to synthesize two different Bt toxins used as insecticides. Approximately 60 different biochemical parameters were classified per organ and measured in serum and urine after 5 and 14 weeks of feeding. GM maize-fed rats were compared first to their respective isogenic or parental non-GM equivalent control groups. This was followed by comparison to six reference groups, which had consumed various other non-GM maize varieties. We applied nonparametric methods, including multiple pairwise comparisons with a False Discovery Rate approach. Principal Component Analysis allowed the investigation of scattering of different factors (sex, weeks of feeding, diet, dose and group). Our analysis clearly reveals for the 3 GMOs new side effects linked with GM maize consumption, which were sex- and often dose-dependent. Effects were mostly associated with the kidney and liver, the dietary detoxifying organs, although different between the 3 GMOs. Other effects were also noticed in the heart, adrenal glands, spleen and haematopoietic system. We conclude that these data highlight signs of hepatorenal toxicity, possibly due to the new pesticides specific to each GM corn. In addition, unintended direct or indirect metabolic consequences of the genetic modification cannot be excluded.

    The poor folks at Monsteranto must be heart-broken over these findings; all they ever wanted to do was feed a hungry world…!
    (If you don’t believe me, go to and do a search on “hungry”. My God, their sense of “Corporate Responsibility” is astounding!)

    That’s the thing, though: no matter how much evil a corporation does, anything and everything can always be justified as a “good”. This is a basic lesson we should be teaching our children, that all events and occurances can be looked at from two very different, often opposite, points of view. That finding the truth between these polar views is not an easy skill to learn, but ultimately a crucial one.

    Actually, the financial markets are a great lesson for this….any price movement ALWAYS has two equally plausible explanations. Thus analysts will line up on both sides to pitch why you’d be stupid not to buy or sell the same situation. With corporate agendas, though, there’s lots of money & influence promoting the “pro”, but there’s rarely any power on the “con” side. Thus our society has been trained like monkeys to refer to corporate pre-emptive warfare as “Defense”, and we’re scripted to believe that it somehow all comes down to “supporting our troops” even while our troops are being shamed and exploited.

    And of course the industrial food-processing industry has no interest in “feeding the world”: if they did, they would very definitely have accomplished it by now!

    “(BTW, the above URL is a typo.)” Oops! I guess I still had my “monsteranto” gag on my mind.

    My take on polar views: sometimes the truth is somewhere in-between, and sometimes one of the poles is just a cynical Goddamn lie. I teach my children about those, too.

    They’re having a circle-jerk over at the “science” reddit, because Discover magazine’s website is running a hit piece on this study. As I posted there (reddit):

    “After more than 30 years of research, there are confirmed health risks associated with DES exposure. However, not all exposed individuals will experience DES-related health problems.”(source:

    30 years of research?! Why’d it take so long? Has Monsanto done 30 years of research on their products?

    Yeah, GMO will never bite us in the ass. We can fuck with the basic building blocks of life using perfectly UNNATURAL methods with absolute impunity. Profit-driven “Science” has proved it! LOL!
