Cancer rats: the continuation of the scandal
Scandalous article about cancer in rats arising from GMOs,
published in another scientific journal
In an article two years ago, the author argued that laboratory rats, which were fed genetically modified corn for two years, grow huge cancerous tumors. The article was subjected to devastating criticism of the scientific community, who pointed out gross errors in the formulation of the experiment and in the statistical calculation of data.
Firstly, Seralini pointed out that the Sprague-Dowley rats taken for the experiment were genetically prone to the formation of cancerous tumors, and in two years they would have arisen anyway. Secondly, the number of rats in each group (10 animals) was clearly insufficient for a correct comparison.
As a result, the article was withdrawn from the journal Food and Chemical Toxicology in November 2013.
This did not prevent Seralini from re-publishing the notorious article in the journal Environmental Sciences Eigore describing the same experiment with feeding rats with genetically modified corn grown in the absence or in the presence of the herbicide Roundup. In the new version, the article has undergone minor changes, but the main conclusions remain the same. The author claims that GM corn led to the fact that the rats developed cancerous tumors faster, larger in size than in the control. It is also said about liver and kidney damage in males and greater mortality of females when feeding them GM corn.
The editorial board of Environmental Sciences explains the publication of the article "in order to ensure a reasonable discussion." "Progress in science needs a clash of different points of view to develop the best methods," said Winfried Schroeder, editor–in-chief of the journal.
The new version of the article did not change the opinion of critics regarding Seralini's work. "This work was and remains flawed," says Richard Goodman, biotechnology editor of the journal Food and Chemical Toxicology.
"The article has not been properly reviewed in terms of statistics, its methods and results remain unclear," says David Spiegelhalten, a statistician at the University of Cambridge. – The announced effects do not show dose dependence, and conclusions are drawn on groups of 10 animals each. This is inadequate." He added that the work needs to be repeated in several independent laboratories on an adequate number of animals.
