I know that we are all hearing more and more about GMO, but this article helped me understand the issue a little better.
Doctors at Sherbrooke University Hospital in Quebec found the corn's Bt-toxin in the blood of pregnant women and their babies, as well as in non-pregnant women. (Specifically, the toxin was identified in 93% of 30 pregnant women, 80% of umbilical blood in their babies, and 67% of 39 non-pregnant women.) The study has been accepted for publication in the peer reviewed journal
Reproductive Toxicology.
According to the UK
Daily Mail, this study, which "appears to blow a hole in" safety claims, "has triggered calls for a ban on imports and a total overhaul of the safety regime for genetically modified (GM) crops and food." Organizations from England to New Zealand are now calling for investigations and for GM crops to be halted due to the serious implications of this finding.
Links to allergies, auto-immune disease, and other disordersThere's already plenty of evidence that the Bt-toxin produced in GM corn and cotton plants is toxic to humans and mammals
andtriggers immune system responses. The fact that it flows through our blood supply, and that is passes through the placenta into fetuses, may help explain the rise in many disorders in the US since Bt crop varieties were first introduced in 1996.
In government-sponsored research in Italy, mice fed Monsanto's Bt corn showed a wide range of immune responses. Their elevated IgE and IgG antibodies, for example, are typically associated with allergies and infections. The mice had an increase in cytokines, which are associated with "allergic and inflammatory responses." The specific cytokines (interleukins) that were elevated are also higher in humans who suffer from a wide range of disorders, from arthritis and inflammatory bowel disease, to MS and cancer (see chart).
Elevated interleukinsAssociationsIL-6Rheumatoid arthritis, inflammatory bowel disease, osteoporosis, multiple sclerosis, various types of cancer (multiple myeloma and prostate cancer)IL-13Allergy, allergic rhinitis, ALS (Lou Gehrig's disease)MIP-1bAutoimmune disease and colitis.IL-12p70Inflammatory bowel disease, multiple sclerosisThe young mice in the study also had elevated T cells (gamma delta), which are increased in people with asthma, and in children with food allergies, juvenile arthritis, and connective tissue diseases. The Bt corn that was fed to these mice, MON 810, produced the same Bt-toxin that was found in the blood of women and fetuses.
When rats were fed another of Monsanto's Bt corn varieties called MON 863, their immune systems were also activated, showing higher numbers of basophils, lymphocytes, and white blood cells. These can indicate possible allergies, infections, toxins, and various disease states including cancer. There were also signs of toxicity in the liver and kidneys.
Natural Bt is dangerousFarmers have used Bt-toxin from soil bacteria as a natural pesticide for years. But they
spray it on plants, where it washes off and biodegrades in sunlight. The GM version is built-in; every plant cell has its own spray bottle. The toxin doesn't wash off; it's consumed. Furthermore, the plant-produced version of the poison is thousands of times more concentrated than the spray; is designed to be even more toxic; and has properties of known allergens—it actually
fails the World Health Organization's allergen screening tests.
The biotech companies ignore the substantial difference between the GM toxin and the natural bacteria version, and boldly claim that since the natural spray has a history of safe use in agriculture, it's therefore OK to put the poison directly into our food. But even this claim of safe use of Bt spray ignores peer-reviewed studies showing just the opposite.
When
natural Bt-toxin was fed to mice, they had tissue damage, immune responses as powerful as cholera toxin, and even started reacting to other foods that were formerly harmless. Farm workers exposed to Bt also showed immune responses. The EPA's own expert Scientific Advisory Panel said that these mouse and farm worker studies "suggest that Bt proteins could act as antigenic and allergenic sources."But the EPA ignored the warnings. They also overlooked studies showing that about 500 people in Washington state and Vancouver showed allergic and flu-like symptoms when they were exposed to the spray when it was used to kill gypsy moths.
Bt cotton linked to human allergies, animal deathsIndian farm workers are suffering from rashes and itching and other symptoms after coming into contact with Bt cotton.Now thousands of Indian farm laborers are suffering from the same allergic and flu-like symptoms as those in the Pacific Northwest simply from handling genetically engineered cotton plants that produce Bt-toxin. According to reports and records from doctors, hospitals, and pharmacies, as well as numerous investigative reports and case studies, workers are struggling with constant itching and rashes; some take antihistamines every day in order to go to work.
Our Institute for Responsible Technology joins other organizations worldwide calling for an immediate ban on GM food crops, and the commencement of rigorous independent scientific research on the safety of GMOs in general, and Bt-toxin in particular.
