Tests on GM Flavr Savr tomatoes resulted in lesions in rats. |

Dr Arpad Pusztai's notorious experiments with GM potatoes and rats showed severe gut problems in the test animals compared to those fed non-GM potatoes. Despite the largely successful attempt to discredit him publicly, Pusztai's paper had been peer reviewed six times prior to publication. Compared to most GM research sponsored by GM companies it remains a model of experimental propriety and credibility.
In GM chicken-feed experiments, twice as many chickens fed GM maize died as those fed the conventional crop. Despite this, the GM maize was approved by the Government but later withdrawn following public pressure. All of the above should make us worry. But the bottom line, of course, is that not nearly enough time has elapsed for us to be in the least confident of GM safety. Meanwhile, what's the best comparable example that the kind of transgenic tampering that is the essence of GM might eventually lead to some pretty grizzly consequences? Well, for about 30 years there was 'hard scientific evidence' that feeding high levels of animal proteins to grazing ruminants (ie dead sheep to live cows) was 'safe', in that no significant health problems seemed to have arisen. Then suddenly, Bingo! We had BSE. The production of GM foods is in many ways comparable. It involves combining strands of DNA, often animal derived, that could never naturally come together, then introducing these mutant strains to both the animal and human food chain. Such unprecedented and unnatural steps are producing entirely new materials for both the biosphere to contend with on the macro scale, and the human gut to deal with on the micro scale. Why should we be in the least surprised if at some point, something very nasty happens?
