DNA from Gene-Modified Crops Found in Human Gut
(London, Reuters Health, 7/17/02)

Scientists at the University of Newcastle, working for Britain's Food Standards Agency, have shown that DNA from genetically engineered food can pass into human intestinal bacteria. The researchers gave each of 7 patients who had had their lower bowels removed, a burger and milkshake containing genetically modified soy and then examined samples of the participants' gut bacteria. They found a modified soy gene in 3 of the 7 samples; however, when the researchers fed the same meal to 12 people with intact digestive tracts, there was no sign of GM material in the subjects' feces.
