GMOs provoke immune reactions
AAEM states, "Multiple animal studies show significant immune dysregulation," including increase in cytokines, which are "associated with asthma, allergy, and inflammation"-all on the rise in the US.
According to GM food safety expert Dr. Arpad Pusztai, changes in the immune status of GM animals are "a consistent feature of all the studies."[xv] Even Monsanto's own research showed significant immune system changes in rats fed Bt corn. [xvi] A November 2008 by the Italian government also found that mice have an immune reaction to Bt corn. [xvii]
GM soy and corn each contain two new proteins with allergenic properties,[xviii] GM soy has up to seven times more trypsin inhibitor-a known soy allergen,[xix] and skin prick tests show some people react to GM, but not to non-GM soy. [xx] Soon after GM soy was introduced to the UK, soy allergies skyrocketed by 50%. Perhaps the US epidemic of food allergies and asthma is a casualty of genetic manipulation.
Animals dying in large numbers
In India, animals graze on cotton plants after harvest. But when shepherds let sheep graze on Bt cotton plants, thousands died. Post mortems showed severe irritation and black patches in both intestines and liver (as well as enlarged bile ducts). Investigators said preliminary evidence "strongly suggests that the sheep mortality was due to a toxin. . . . most probably Bt-toxin."[xxi] In a small follow-up feeding study by the Deccan Development Society, all sheep fed Bt cotton plants died within 30 days; those that grazed on natural cotton plants remained healthy.
In a small village in Andhra Pradesh, buffalo grazed on cotton plants for eight years without incident. On January 3rd, 2008, the buffalo grazed on Bt cotton plants for the first time. All 13 were sick the next day; all died within 3 days. [xxii]
Bt corn was also implicated in the deaths of cows in Germany, and horses, water buffaloes, and chickens in The Philippines. [xxiii]
In lab studies, twice the number of chickens fed Liberty Link corn died; 7 of 20 rats fed a GM tomato developed bleeding stomachs; another 7 of 40 died within two weeks. [xxiv] Monsanto's own study showed evidence of poisoning in major organs of rats fed Bt corn, according to top French toxicologist G. E. Seralini. [xxv]
Worst finding of all-GMOs remain inside of us
The only published human feeding study revealed what may be the most dangerous problem from GM foods. The gene inserted into GM soy transfers into the DNA of bacteria living inside our intestines and continues to function. [xxvi] This means that long after we stop eating GMOs, we may still have potentially harmful GM proteins produced continuously inside of us. Put more plainly, eating a corn chip produced from Bt corn might transform our intestinal bacteria into living pesticide factories, possibly for the rest of our lives.
When evidence of gene transfer is reported at medical conferences around the US, doctors often respond by citing the huge increase of gastrointestinal problems among their patients over the last decade. GM foods might be colonizing the gut flora of North Americans.
Warnings by government scientists ignored and denied
Scientists at the Food and Drug Administration (FDA) had warned about all these problems even in the early 1990s. According to documents released from a lawsuit, the scientific consensus at the agency was that GM foods were inherently dangerous, and might create hard-to-detect allergies, poisons, gene transfer to gut bacteria, new diseases, and nutritional problems. They urged their superiors to require rigorous long-term tests. [xxvii] But the White House had ordered the agency to promote biotechnology and the FDA responded by recruiting Michael Taylor, Monsanto's former attorney, to head up the formation of GMO policy. That policy, which is in effect today, denies knowledge of scientists' concerns and declares that no safety studies on GMOs are required. It is up to Monsanto and the other biotech companies to determine if their foods are safe. Mr. Taylor later became Monsanto's vice president.
Dangerously few studies, untraceable diseases
AAEM states, "GM foods have not been properly tested" and "pose a serious health risk." Not a single human clinical trial on GMOs has been published. A 2007 review of published scientific literature on the "potential toxic effects/health risks of GM plants" revealed "that experimental data are very scarce." The author concludes his review by asking, "Where is the scientific evidence showing that GM plants/food are toxicologically safe, as assumed by the biotechnology companies?"[xxviii]
