For the first time, it has been proved that bacteria in the human gut can take up DNA from genetically modified food. Harry Gilbert and colleagues at the University of Newcastle upon Tyne made the discovery, after feeding volunteers with a burger and a milk shake containing GM soya. Crucially, in three of the seven, he found that bacteria had taken up GM DNA from the soya. But "despite exhaustive attempts", he could not isolate the precise bacteria which had taken up the GM DNA. He concludes that the DNA must have been taken up only by tiny proportions of gut bacteria.
Full story can be found in the New Scientist, July 18, 2002.
