A highly controversial paper by Prof Gilles-Eric Seralini and colleagues has been republished after a stringent peer review process. The chronic toxicity study examines the health impacts on rats of eating a commercialized genetically modified (GM) maize, Monsanto's NK603 glyphosate-based herbicide Roundup. Toxic effects were found from the GM maize tested alone, as well as from Roundup tested alone and together with the maize. Additional unexpected findings were higher rates of large tumours and mortality in most treatment groups. |
