The EU's food safety agency definitively rejected Wednesday a bombshell French report linking genetically modified corn to cancer, saying it failed to meet "acceptable scientific standards."

"Serious defects in the design and methodology of a paper by Seralini et al. mean it does not meet acceptable scientific standards," the European Food Safety Authority said in a statement.

"Consequently it is not possible to draw valid conclusions about the occurrence of tumours in the rats tested," the agency said.

EFSA, which reviews the use and authorization of GMOs (Genetically Modified Organisms), added that it "finds there is no need to re-examine its previous safety evaluations of NK603," the genetically modified maize developed by US agribusiness giant Monsanto.

That same conclusion had been reached in separate and independent assessments of Gilles-Eric Seralini's work carried out in six European Union nations, the agency added.

Seralini's research team at France's University of Caen issued a report in September concluding that rats fed on NK603 corn, or exposed to one of Monsanto's weedkillers used with the corn strain, and containing glyphosate, developed tumours.
