  • Study demonstrates the toxicity of three GM corn varieties from Monsanto

    Three GM corn varieties were shown to be toxic to rat kidney and liver. Other effects were observed 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”

    Abstract

    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.

  • Germany bans Monsanto MON810 GM Corn

    Germany’s Minister of Agriculture, Ilse Aigner announced a decision today to ban the cultivation Monsanto’s MON810 genetically modified Bt maize (corn), due to serious health, agricultural, and ecological concerns.

    4 out of 5 German consumers are opposed to the importation of the maize, and the German BMELF (Federal Minsitry of Food, Agriculture, and Consumer Protection) decision reflects that view.

    MON810, also known as YieldGard, is genetically modified to express an insecticide (Cry1Ab) that naturally in bacterium Bacillus thuringiensis (Bt).

    This Bt maize has been approved for human consumption and animal feed in the US, unlabelled, since 1996, [1] and many other countries, despite significant risk to humans and other species.

    A 2007 study by Greenpeace showed inconsistent levels of Bt toxin expressed between plants when grown in non-controlled agricultural settings.  The study found that levels of the toxic protein in some plants were up to 100 times lower than Monsanto claimed, raising questions about both the effectiveness of the plant at controlling pests, and the actual potency of the expressed pesticide. [3]

    A US Environmental Protection Agency (EPA) risk assessment study that concluded the maize was safe for human consumption was based on 3 studies in mice, and none in humans.

    Richard Wolfson, PhD points out the recklessness of using the Bt maize in light of wofeul inadequacy of existing research.  There exists a likelyhood of ampicillin (antibiotic) resistant bacteria forming in animals that consume the corn.   The use of Bt corn and other crops will almost certainly selectively breed stronger pests that threaten organic crops, and they have been shown to harmful to beneficial insect species [2].

    It is poorly understood whether genes from Bt maize will transfect other corn, permanently affecting gene lines of non-GM crops.

    Unfortunately in many western countries, especially the US, big agribusiness and biotechnology industry has a stranglehold on regulatory agencies.  In the US, produce labeled as organic (indicated by a number 9 before the PLU number) may not be genetically modified.  Any produce not labelled organic may be GMO (genetically modified organisms), and even perpared, mixed foods labeled as organic, may contan GMOs.
