So: the report of the controversial, long-term rat feeding study of Monsanto’s genetically modified (GM) NK603 maize and Roundup (glyphosate) herbicide, performed by Professor Gilles-Eric Séralini et al, is being retracted. This is a clearly politically motivated decision by the journal Food and Chemical Toxicology (FCT), unjustifiable on scientific grounds alone, that continues a shameful pattern of science bowing to corporate interests.


Corporate enemy number one

The increased tumour incidence and shortened lifespan of rats observed in the admittedly imperfect Séralini et al study revealed disturbing implications about the longer-term toxicity of both Roundup herbicide and NK603 Roundup-tolerant GM maize. The knives have been out for Séralini et al ever since.

To its credit, FCT had acted honourably up to this point. It published letters both critical and supportive of the Séralini et al paper and allowed the French researchers to answer their critics in print.

Double standards

Now, however, the FCT’s editor, Dr A Wallace Hayes, has opted to retract Séralini et al’s 2012 paper. In Dr Hayes’ retraction statement, he spoke of “Legitimate cause for concern regarding both the number of animals in each study group and the particular strain selected”. Séralini et al have previously dealt with these exact criticisms in detail. The crucial point here is that all Séralini et al essentially did was extend Monsanto’s 2004 rat feeding protocol – also published in FCT – across the rats’ entire lifespan, while adding an extra arm studying the effects of Monsanto’s herbicide that accompanies NK603 in the field, Roundup. In short, as Prof Séralini pointed out in his official response to Dr Hayes, “A factual comparative analysis of [our] rat feeding trial…and the Monsanto trials clearly reveals that if the Séralini experiments are considered to be insufficient to demonstrate harm, logically, it must be the same for those carried out by Monsanto to prove safety.” EFSA, perhaps the most influential of Séralini et al’s critics, appears quietly to agree.

Politics, not science

In his statement, Dr Hayes also stressed that “Ultimately, the results presented (while not incorrect) are inconclusive, and therefore do not reach the threshold of publication for Food and Chemical Toxicology.

But hold on a minute. Science is surely an ongoing conversation between researchers, not a procession of definitive statements. When a paper is published that asks important questions or offers new avenues for further research, follow-up studies are performed and science moves on. That’s how it’s supposed to work, anyway – but as we’ve seen in cases like those of Dr Arpad Pusztai, Ignacio Chapela and David Quist, and Dr Judy Carman in the world of GM research, and Dr Andrew Wakefield elsewhere, the practice of science is all to easily derailed by corporate–governmental interests.

The scientific publishing industry even has guidelines, to which FCT is a signatory, specifying when retraction is appropriate. These clearly do not apply in the case of Séralini et al, as pointed out by the European Network of Scientists for Social and Environmental Responsibility (ENSSER).

Even Dr Hayes may appreciate the absurdity of the situation. In his retraction statement, he admits that his review of Séralini et al’s raw data “Found no evidence of fraud or intentional misrepresentation of the data”. We can only imagine his embarrassment at being forced to rely on the scientifically unsupportable ‘inconclusive results’ gambit to justify pulling the paper.

Corporate science at Elsevier?

Meet Richard E Goodman. Mr Goodman was appointed to a brand-new position at FCT – Associate Editor for Biotechnology – in early 2013, several months after Séralini et al was published. He also used to work for Monsanto and has ongoing links with the International Life Sciences Institute (ILSI), a notorious big business front group. Soon after Mr Goodman was parachuted onto the FCT board, the journal retracted two articles, including a Brazilian paper that questioned the safety of the Bacillus thuringiensis (Bt) toxin present in many GM crops. Furthermore, FCT’s conflicts of interest don’t end there, and Elsevier, FCT’s publisher, has form.

All in all, we agree 100% with GMWatch: the “Journal retraction of Séralini study is illicit, unscientific, and unethical”.

Put even more simply: it’s bad science.

What next for Séralini et al?

Prof Séralini is so far standing firm against this outrageous – although sadly commonplace – hijacking of the scientific process by big business. He is refusing to voluntarily retract the paper and has threatened a lawsuit against FCT if it withdraws the article.

Another option would be to get his data published elsewhere – exactly as the Brazilian researchers did. If successful, republication would not only demonstrate the integrity of Prof Séralini’s group’s research; it would also draw inevitable attention to FCT’s politically driven retraction.

The final piece of context may come from two forthcoming, long-term GM studies being funded by the European Commission and the French government. The French study in particular was inspired by Séralini et al, and it will be interesting to observe the organisers’ response to recent events.

Foot, meet bullet

As much as this episode looks like a severe blow to the anti-GM movement – actually the ‘pro-real food’ movement – it may be that the GM lobby has actually shot itself in the foot. The GM cat has been out of the bag for some time, and the latest twist in the Séralini affair makes it screamingly obvious that the biotech industry will go to any lengths to keep the public in the dark. A very public lawsuit will only assist that enlightenment process.

Whatever Prof Séralini opts to do next, we wish him well.
