TWO expert panels yesterday rejected a French study linking genetically-modified corn to tumors in rats but called for wider probes into issues raised by the contested research.
Acting on a government request to deliver a fast-track verdict, the two groups of specialists reported they found no evidence to back what the study said.
The Higher Biotechnologies Council and the National Agency for Food Safety said they saw nothing to challenge existing safety assessments for Monsanto's NK603 corn or its Roundup weed killer, which was part of the experiment.
"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," said the 66-member HCB, set up in 2009 to provide an independent view.
"The data are insufficient to establish scientifically a causal link... or to support the conclusions or pathways suggested by the authors," ANSES said.
But both called for a broader investigation to guide a public left rattled or confused by the debate.
The HCB said the inquiry should look into whether NK603 had long-term impacts on health, while ANSES urged a probe into any consequences of combined exposure to NK603 and Roundup. Both issues were explored in the study.
The storm was unleashed in September by researchers led by Gilles-Eric Seralini at the University of Caen in Normandy, who said rats fed with the genetically-modified corn and/or doses of Roundup developed tumors.
The paper unleashed a storm in environmentally-sensitive Europe, where GM crops face many restrictions.
NK603 has been engineered to make it resistant to Roundup, so that farmers can douse fields with the Monsanto weed killer in a single go, offering savings.
Seralini said his experiment was the first to test GM corn on rodents' normal life span of two years, as opposed to the standard 90 days. He said NK603 and Roundup both caused tumors, whether they were consumed together or on their own.
But critics faulted the experimental methods and data and accused him of manipulating the media to gain scary headlines. In an exceptional move, six French science academies last Friday branded the work as flawed and said it had "spread fear among the public."
Seralini said he welcomed a wider investigation but said that in the meantime, NK603 should be banned.
"A two-year study takes four years to set up and analyze, and during these four years, who else is going to fall sick or die because of these poorly-tested products?" he said.
Monsanto said at its French headquarters in Lyon that "it took note" of the HCB's findings and said the recommended probe "does not change risk assessments" for NK603.
