Richard Smith, former editor of the British Medical Journal, has jested that instead of scientific peer review, its rival The Lancet had a system of throwing a pile of papers down the stairs and publishing those that reached the bottom. On another occasion, Smith was challenged to publish an issue of the BMJ exclusively comprising papers that had failed peer review and see if anybody noticed. He replied, "How do you know I haven't already done it?"

As Smith's stories show, journal editors have a lot of power in science - power that provides opportunities for abuse. The life science industry knows this, and has increasingly moved to influence and control science publishing.

The strategy, often with the willing cooperation of publishers, is effective and sometimes blatant. In 2009, the scientific publishing giant Elsevier was found to have invented an entire medical journal, complete with editorial board, in order to publish papers promoting the products of the pharmaceutical manufacturer Merck. Merck provided the papers, Elsevier published them, and doctors read them, unaware that the Australasian Journal of Bone and Joint Medicine was simply a stuffed dummy.

Fast forward to September 2012, when the scientific journal Food and Chemical Toxicology (FCT) published a study that caused an international storm (Séralini, et al. 2012). The study, led by Prof Gilles-Eric Séralini of the University of Caen, France, suggested a Monsanto genetically modified (GM) maize, and the Roundup herbicide it is grown with, pose serious health risks. The two-year feeding study found that rats fed both suffered severe organ damage and increased rates of tumors and premature death. Both the herbicide (Roundup) and the GM maize are Monsanto products. Corinne Lepage, France's former environment minister, called the study "a bomb".

Subsequently, an orchestrated campaign was launched to discredit the study in the media and persuade the journal to retract it. Many of those who wrote letters to FCT (which is published by Elsevier) had conflicts of interest with the GM industry and its lobby groups, though these were not publicly disclosed.

The journal did not retract the study. But just a few months later, in early 2013 the FCT editorial board acquired a new "Associate Editor for biotechnology", Richard E. Goodman. This was a new position, seemingly established especially for Goodman in the wake of the "Séralini affair".

Richard E. Goodman is professor at the Food Allergy Research and Resource Program, University of Nebraska. But he is also a former Monsanto employee, who worked for the company between 1997 and 2004. While at Monsanto he assessed the allergenicity of the company's GM crops and published papers on its behalf on allergenicity and safety issues relating to GM food (Goodman and Leach 2004).

Goodman had no documented connection to the journal until February 2013. His fast-tracked appointment, directly onto the upper editorial board raises urgent questions. Does Monsanto now effectively decide which papers on biotechnology are published in FCT? And is this part of an attempt by Monsanto and the life science industry to seize control of science?

To equate one journal with "science" may seem like an exaggeration. But peer-reviewed publication, in the minds of most scientists, is science. Once a paper is published in an academic journal it enters the canon and stands with the discovery of plate tectonics or the structure of DNA. All other research, no matter how groundbreaking or true, is irrelevant. As a scientist once scathingly said of the "commercially confidential" industry safety data that underpin approvals of chemicals and GM foods, "If it isn't published, it doesn't exist."

Goodman's ILSI links


The industry affiliations of FCT's new gatekeeper for biotechnology are not restricted to having worked directly for Monsanto. Goodman has an active and ongoing involvement with the International Life Sciences Institute (ILSI). ILSI is funded by the multinational GM and agrochemical companies, including Monsanto. It develops industry-friendly risk assessment methods for GM foods and chemical food contaminants and inserts them into government regulations.

ILSI describes itself as a public interest non-profit but its infiltration of regulatory agencies and influence on risk assessment policy has become highly controversial in North America and Europe. In 2005 US-based non-profits and trade unions wrote to the World Health Organization (WHO) protesting against ILSI's influence on international health standards protecting food and water supplies. As a result, the WHO barred ILSI from taking part in WHO activities setting safety standards, because of its funding sources. And in Europe in 2012, Diana Banati, then head of the management board at the European Food Safety Authority (EFSA), had to resign over her undisclosed long-standing involvement with ILSI (Robinson et al. 2013).

Goodman's appointment to FCT is surprising also for the fact that the journal already has expertise in GM food safety. Of the four senior editors, José L. Domingo is a professor of toxicology and environmental health and author of two comprehensive reviews of GM food safety studies (Domingo 2007; Domingo and Bordonaba 2011). Both reviews expressed skepticism of the thesis that GMOs are safe. Consequently, it is far from clear why FCT needs an "associate editor for biotechnology", but it is clear why Monsanto would have an interest in ensuring that the "Séralini affair" is never repeated.

Editing the scientific record: The case of Paul Christou

FCT is not the only academic journal that appears to have been captured by commercial interests. After the initial campaign failed to get FCT to retract the Séralini study, the journal Transgenic Research published a heavy-handed critique of the study and of the researchers themselves (Arjo et al., 2013). The lead author of that critique was Paul Christou.

Christou and co-authors castigated the editor of FCT for publishing the study, calling it "a clear and egregious breach of the standards of scientific publishing". They insisted that the journal editor retract the study "based on its clearly flawed data, its breaches of ethical standards, and the strong evidence for scientific misconduct and abuse of the peer-review process". "Even a full retraction of the Séralini article" wrote Christou, "will not cleanse the Internet of the inflammatory images of tumorous rats."

The same writers further implied that the Séralini study was "fraudulent", that the researchers failed to analyse the data objectively, and that the treatment of the experimental animals was inhumane.

This is not the first time Christou has attacked scientific findings that have raised doubts about GM crops. In 2001 Ignacio Chapela and David Quist of the University of California, Berkeley, reported in the journal Nature that indigenous Mexican maize varieties had become contaminated with GM genes (Quist and Chapela, 2001). This issue was, and remains, highly controversial since Mexico is the genetic centre of origin for maize. In an exact parallel with the Séralini study, an internet campaign was waged against Chapela and Quist demanding that the journal retract the study. Then Christou, just as he was later to do with the Séralini study, attacked Chapela and Quist's paper in an article in Transgenic Research. The title said it all: "No credible scientific evidence is presented to support claims that transgenic DNA was introgressed into traditional maize landraces in Oaxaca, Mexico" (Christou, 2002).

Responding to the campaign, Nature editor Philip Campbell asked Chapela and Quist for more data, which they provided, and arranged another round of peer review. Only one reviewer in the final group of three supported retraction, and no one had presented any data or analysis that contradicted Chapela and Quist's main finding. Nevertheless, Nature asserted, "The evidence available is not sufficient to justify the publication of the original paper". Some subsequent investigations, testing different samples, reported finding GM genes in native landraces of Mexican corn (Pineyro-Nelson et al. 2009), while others did not (Ortiz-Garcia et al. 2005).

Paul Christou, in contrast, probably did not have much trouble getting either of his critiques published in Transgenic Research. He is the journal's editor-in-chief. And, like Goodman, Christou is connected to Monsanto. Monsanto bought the GM seed company Agracetus (Christou's former employer) and Monsanto now holds patents for the production of GM crops on which Christou is named as the inventor. It is normal practice to declare inventor status on patents as a competing interest in scientific articles, but Christou did not disclose either conflict of interest - his editorship of the journal or his patent inventor status - in his critique of the Séralini study.

The Ermakova affair: Preemptive editing of the scientific record

Not only can journal editors prevent the publication of research showing problems with GM crops in their own journals - they can effectively prevent publication elsewhere. In 2007, the leading academic journal Nature Biotechnology featured an extraordinary attack on the work of Russian scientist, Irina Ermakova (Marshall, 2007). Her laboratory research had found decreased weight gain, increased mortality, and decreased fertility in rats fed GM Roundup-tolerant soy over several generations (Ermakova, 2006; Ermakova, 2009).

The editor of Nature Biotechnology, Andrew Marshall, contacted Ermakova, inviting her to answer questions about her findings, which she had only presented at conferences. He told her it was "an opportunity to present your own findings and conclusions in your own words, rather than a critique from one side". Ermakova agreed.

The process that followed was as deceptive as it was irregular. The editor sent Ermakova a set of questions about her research, which she answered. In due course she was sent a proof of what she thought was to be 'her' article, with her byline as author.

However, the article that was finally published was very different. Ermakova's byline had been removed and Marshall's substituted. Each of Ermakova's answers to the questions was followed by a lengthy critique by four pro-GM scientists (Marshall, 2007). The proof sent to Ermakova, now revealed as a 'dummy proof', had not included these critical comments. Consequently, she was denied the chance to address them in the same issue of the journal. And in the final article the editor had preserved the critics' references but removed many of Ermakova's, with the effect that her statements appeared unsubstantiated.
