French panel rejects study linking GM corn to cancer

FRANCE: An investigative panel on Monday rejected a contested French study that linked genetically-modified corn to cancer in rats but called for a "long-term, independent" probe into the issue to advise the public.

The Higher Biotechnologies Council (HCB) said it found "no causal relationship" between the rats' tumours and consumption of Monsanto's NK603 GM corn or the Roundup herbicide that was part of the experiment.

The experiment's methods were also "unsuitable," it said, in a report made at the government's request.

"The scientific committee (of the HCB) concludes that the study provides no scientific information regarding the detection of any health risk linked to NK603 corn, whether it was treated with Roundup or not." "The HCB's Economic, Ethical and Social Committee, for its part, affirms that the study is not conclusive.

"However, in order to answer the public's questions, the committee recommends that a long-term, independent, transparent study, with adversarial views, be undertaken under government auspices." In September, a team of researchers led by Gilles-Eric Seralini at the University of Caen, published a long-term study that said rats fed with Monsanto's NK603 corn and/or doses of Roundup developed tumours.

The paper, published in a peer-reviewed science journal, unleashed a storm in environmentally-sensitive Europe, where GM products are subject to widespread restrictions.

NK603 has been engineered to make it resistant to Monsanto's herbicide Roundup. This enables farmers to douse fields with the weed killer in a single go, thus offering substantial savings.

Seralini said his experiment was the first to test GM corn rodents' normal lifespan of two years, as opposed to the standard 90 days. Two hundred male and female rats were split into 10 groups of 10 animals.

One was a "control" group which was given ordinary rat food that contained 33 percent non-GM corn, and plain water.

Three groups were given ordinary rat food and water with increasing doses of Roundup, reflecting various concentrations of the herbicide in the food chain.

The other six were fed rat food of which 11, 22 or 33 percent comprised NK603 corn, either treated or not with Roundup when the corn was grown.

The researchers said they found that NK603 and Roundup both caused similar damage to the rats' health, whether they were consumed together or on their own. AFP
