A scientific study that identified serious health impacts on rats fed on ‘Roundup ready’ GMO maize has been republished following its controversial retraction under strong commercial pressure. Now regulators must respond and review GMO and agro-chemical licenses, and licensing procedures.This study has arguably prevailed through the most comprehensive and independent review process to which any scientific study on GMOs has ever been subjected.
A highly controversial paper by Prof Gilles-Eric Séralini 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.
The original study, published in Food and Chemical Toxicology (FCT) in September 2012, found severe liver and kidney damage and hormonal disturbances in rats fed the GM maize and low levels of Roundup that are below those permitted in drinking water in the EU.
However it was retracted by the editor-in-chief of the Journal in November 2013 after a sustained campaign of criticism and defamation by pro-GMO scientists.
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.
Criticisms addressed in the new version
Now the study has been republished by Environmental Sciences Europe. The republished version contains extra material addressing criticisms of the original publication.
The raw data underlying the study’s findings are also published – unlike the raw data for the industry studies that underlie regulatory approvals of Roundup, which are kept secret. However, the new paper presents the same results as before and the conclusions are unchanged. …
