FOOD PRODUCTION DAILY– Monsanto’s genetically modified maize MON863, authorised for human consumption since 2006, showed signs of liver and kidney toxicity in a rat study, raising concerns about its safety.

The study, performed by French researchers from the independent CRIIGEN (Committee for Independent Research and Genetic Engineering), based at the University of Caen reports that rats fed the maize for three months showed signs of liver and kidney toxicity, as well as differences in weight gain between the sexes.

“Our counter-evaluation show that there are signs of toxicity and that nobody can say scientifically and seriously that consumption of the transgenic maize MON863 is safe and good for health,” lead author of the study, Professor Gilles Eric Séralini told France’s TF1 television station.

MON863 is a transgenic maize genetically modified to express the Bt-toxin (Cry3Bb1) which enables the plant to be insect repellent against the corn rootworm pest. It is different from other GM corns of the market since these express the Cry1Ab toxin which is toxic to the European corn borer.

The study, published on-line in the peer-review journal Archives of Environmental Contamination and Toxicology, fed young adult Sprague-Dawley-derived rats (aged six weeks at the start of the experiment) diets containing 11 or 30 per cent MON863, or diets containing non-GM corn for 90 days.

At the end of the study, Séralini and his team found signs of toxicity in the liver and kidneys of rats fed the MON863 maize, as well as changes to weight between the sexes. Indeed, male rats were found to have lost, on average, 3.3 per cent of their body weight, while females gained 3.7 per cent.
