The Bt-toxin produced in GM plants, however, is thousands of times more concentrated than natural Bt spray, is designed to be more toxic,[x] has properties of an allergen, and unlike the spray, cannot be washed off the plant.
Moreover, studies confirm that even the less toxic natural bacterial spray is harmful. When dispersed by plane to kill gypsy moths in the Pacific Northwest, about 500 people reported allergy or flu-like symptoms. Some had to go to the emergency room. [xi],[xii]
The exact same symptoms are now being reported by farm workers throughout India, from handling Bt cotton. [xiii] In 2008, based on medical records, the Sunday India reported, "Victims of itching have increased massively this year . . . related to BT cotton farming."[xiv]
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]
