Monsanto’s GMO Corn Linked To Organ Failure, Study Reveals

By Katherine Goldstein, Huffington Post

In a study released by the International Journal of Biological Sciences, analyzing the effects of genetically modified foods on mammalian health, researchers found that agricultural giant Monsanto’s GM corn is linked to organ damage in rats.

According to the study, which was summarized by Rady Ananda at Food Freedom, “Three varieties of Monsanto’s GM corn – Mon 863, insecticide-producing Mon 810, and Roundup® herbicide-absorbing NK 603 – were approved for consumption by US, European and several other national food safety authorities.”

Monsanto gathered its own crude statistical data after conducting a 90-day study, even though chronic problems can rarely be found after 90 days, and concluded that the corn was safe for consumption. The stamp of approval may have been premature, however.


In the conclusion of the IJBS study, researchers wrote:

“Effects were mostly concentrated in kidney and liver function, the two major diet detoxification organs, but in detail differed with each GM type. In addition, some effects on heart, adrenal, spleen and blood cells were also frequently noted. As there normally exists sex differences in liver and kidney metabolism, the highly statistically significant disturbances in the function of these organs, seen between male and female rats, cannot be dismissed as biologically insignificant as has been proposed by others. We therefore conclude that our data strongly suggests that these GM maize varieties induce a state of hepatorenal toxicity….These substances have never before been an integral part of the human or animal diet and therefore their health consequences for those who consume them, especially over long time periods are currently unknown.”

Monsanto has immediately responded to the study, stating that the research is “based on faulty analytical methods and reasoning and do not call into question the safety findings for these products.”

The IJBS study’s author Gilles-Eric Séralini responded to the Monsanto statement on the blog, Food Freedom, “Our study contradicts Monsanto conclusions because Monsanto systematically neglects significant health effects in mammals that are different in males and females eating GMOs, or not proportional to the dose. This is a very serious mistake, dramatic for public health. This is the major conclusion revealed by our work, the only careful reanalysis of Monsanto crude statistical data.”

  1. one should be careful about taking for granted the “facts” in just one study, not corroborated by independent third parties. Goes both ways.


    I’m glad that research is being done about GMO effects on the digestive system. I don’t understand why this evidence doesn’t lead to FDA ensuring labeling and companies like Monsanto taking pesticides like Roundup off the market.

  3. I recently asked a checker at a grocery store if a certain product was gmo and he asked what “was did that mean?” Now I live in Northern California and he was in his 20s so that shocked me to the core. This information need to keep getting out over and over. People are not getting it.

  4. Hi ShutyerLips, thanks for the comment! This article was updated on 05/25/11, so it’s not three years old, and it does have a follow-up. We are also in beta mode and are still working out the kinks when it comes to dates on article pages.

  5. Good point to be made…but isn’t this article almost 3 years old? Maybe post some of the follow-ups? Developments? Or at least let readers know why you are posting such an old piece.

  6. Great article. I wish there was a way to let all the public know about the dangers of GMO foods. I always publish articles like this on facebook to get the word out!

  7. I agree not enough research has been done on genetically modified foods.

    Organic is the best route to go.
