I am, without reservations, quite happy to be one of the hundreds of millions of people around the world who eat GM food daily with absolutely no ill effects . . .

The genetic modification of all living organisms made possible by in vitro gene manipulation is set to become the major technological revolution of the 21st century. Ever since this technique became possible in the mid seventies, the foundation has been set for unimaginable advances in medicine, agriculture and every form of human endeavour. The intrinsic value of this technology and the remarkable advances made with the genome project, human and animal cloning, and stem cell research make genetic engineering unstoppable. Furthermore, someone wrote in New Scientist that, at this point, GM is still in its infancy; it’s at the Model T stage. What is about to happen in the next few generations will transform society in ways few can imagine.

Consequently it is unfortunate that in his letter, “Modified crops” (The Witness, April 24), Andrew Taynton perpetuates the same tired old anti-GM sophistry and misinformation. Not all the misinformation is deliberate. Often it is because people are not scientists and are ignorant of the facts. For example, to scare people, he has repeatedly used the stories about the toxicity of “GM”-tryptophan and also the perceived link between cancer and bovine growth hormone (BGH). The tryptophan story, which has now reached the text books, was easily shown to be nonsense. There is no such thing as GM-tryptophan and BGH has nothing whatsoever to do with genes. Another scare story, the threat of “super weeds”, has been debunked in a recent issue of Nature.

In his letter Taynton once again uses the publication in the prestigious journal The Lancet of Dr Pusztai’s negative findings on GM potatoes to justify his anti-GM stance. Taynton knows that The Lancet’s decision to publish Dr Puzstai’s work in no way vindicated his findings. At the time an editorial in the New Scientist warned against such misinformation! It said the decision by the journal to publish was not a vindication, but more to do with getting the results in the open. And there was a problem getting them published, because several of the experts asked to review the results said they were too inconclusive to be published.

Typically anti-GM letters are crammed full of all sorts of studies using rats and other animals to prove the dangers of GM, and this letter does not disappoint. It includes nonsensical and meaningless gems such as, “Twelve cows fed GM maize in Germany died mysteriously. And twice the number of chickens died when fed GM maize compared to those fed natural maize”. And there is always reference to “massive smear campaigns”. An epidemiologist has recently shown that at least 50% of these types of studies are subsequently proved wrong and most remind me of the study carried out in the pre-GM sixties on rats fed cornflakes. The group fed the cardboard cornflakes container flourished; those fed the cornflakes eventually died of malnutrition.

No GM bashing letter would be incomplete without the “scientific peer review studies” to show the poor yields from GM crops. Cotton is a favourite. I inadvertently attended an anti-GM strategy meeting, where we were told how poor GM cotton yields were on the same day that Business Report announced that cotton yields in SA were up 21% because of Bt cotton!

Finally, I find quite pathetic the statement by the SA maize expert Janet Howard from Bristol (“Food aid for Africa”, The Witness, April 27), that “some of her friends from the UK may well prefer to visit New Zealand and Australia on holiday so that they don’t have to eat the GM food this country has to offer”.

Unlike these timid creatures, I am, without reservations, quite happy to be one of the hundreds of millions of people around the world who eat GM food daily with absolutely no ill effects.
