France: Monsanto’s GMO Corn Causes Cancer, Organ Damage in Rats
September 20th, 2012Update: Study Linking GM Maize to Rat Tumors Retracted, Author Unrepentant
Via: Nature:
Bowing to scientists’ near-universal scorn, the journal Food and Chemical Toxicology today fulfilled its threat to retract a controversial paper that claimed that a genetically modified (GM) maize causes serious disease in rats after the authors refused to withdraw it.
The paper, from a research group led by Gilles-Eric Séralini, a molecular biologist at the University of Caen, France, and published in 20121, showed “no evidence of fraud or intentional misrepresentation of the data”, said a statement from Elsevier, which publishes the journal. But the small number and type of animals used in the study means that “no definitive conclusions can be reached”. The known high incidence of tumours in the Sprague-Dawley rat ”cannot be excluded as the cause of the higher mortality and incidence observed in the treated groups”, it added.
Today’s move came as no surprise. Earlier this month, the journal’s editor-in-chief, Wallace Hayes, threatened retraction if Séralini refused to withdraw the paper, which is exactly what he announced at a press conference in Brussels this morning. Séralini and his team remained unrepentant, and allege that the retraction derives from the journal’s editorial appointment of biologist Richard Goodman, who previously worked for biotechnology giant Monsanto for seven years.
“The magazine reviewed our paper more than any other,” says co-author and medical doctor Joël Spiroux, who is also president of the Paris-based Committee for Research and Independent Information on Genetic Engineering (CRIIGEN), which collaborated in the study. The retraction is “a public-health scandal”, he says.

Update / Predictable: Nothing to See Here
Via: New York Times:
Two additional panels of experts in France said the rat study does not change their view of Monsnto’s engineered corn or the Roundup herbicide. See the postscript below.]
An intensively promoted and controversial French study claiming to find high tumor rates and early mortality in rats fed genetically modified corn and “safe” levels of the herbicide Roundup has been dismissed in a rare joint statement from France’s six scientific academies.

Rats, GMO Corn, RoundUp
Americans are literally made of the stuff: King Corn:
Via: AFP:
France’s government on Wednesday asked a health watchdog to carry out a probe, possibly leading to EU suspension of a genetically-modified corn, after a study in rats linked the grain to cancer.
Agriculture Minister Stephane Le Foll, Ecology Minister Delphine Batho and Health and Social Affairs Minister Marisol Touraine said they had asked the National Agency for Health Safety (ANSES) to investigate the finding.
“Depending on ANSES’ opinion, the government will urge the European authorities to take all necessary measures to protect human and animal health,” they said in a joint statement.
“(The measures) could go as far as invoking emergency suspension of imports of NK603 corn to Europe pending a re-examination of this product on the basis of enhanced assessment methods.”
Earlier, French scientists led by Gilles-Eric Seralini at the University of Caen in Normandy unveiled a study that said rats fed with NK603 corn or exposed to the weedkiller used with it developed tumours.
NK603 is a corn, also called maize, made by US agribusiness giant Monsanto.
It has been engineered to make it resistant to Monsanto’s herbicide Roundup.
This enables farmers to douse fields with the weedkiller in a single go, thus offering substantial savings.
Genetically modified (GM) crops are widely grown in North America, Brazil and China but are a hot-button issue in Europe.
The study, published in the peer-reviewed journal Food and Chemical Toxicology, says it is the first to look at rats over their normal lifespan of two years.
“For the first time ever, a GM organism and a herbicide have been evaluated for their long-term impact on health, and more thoroughly than by governments or the industry,” Seralini told AFP. “The results are alarming.”
Two hundred male and female rats were split into 10 groups of 10 animals.
One was a “control” group which was given ordinary rat food that contained 33 percent non-GM corn, and plain water.
Three groups were given ordinary rat food and water with increasing doses of Roundup, reflecting various concentrations of the herbicide in the food chain.
The other six were fed rat food of which 11, 22 or 33 percent comprised NK603 corn, either treated or not with Roundup when the corn was grown.
The researchers found that NK603 and Roundup both caused similar damage to the rats’ health, whether they were consumed together or on their own.
Premature deaths and sickness were concentrated especially among females.
At the 14-month stage of experiment, no animals in the control groups showed any signs of cancer, but among females in the “treated” groups, tumours affected between 10 and 30 percent of the rodents.
“By the beginning of the 24th month, 50-80 percent of female animals had developed tumours in all treated groups, with up to three tumours per animal, whereas only 30 percent of controls were affected,” it said
Males which fell sick suffered liver damage, developed kidney and skin tumours and digestive problems.

Monsanto is evil. No doubt of that. However, this study is getting well deserved criticism.
Some of it here.

I don’t know if the criticism is well-deserved or not. But it should be no surprise that the backlash is going to be very, very vicious. BBC ran a full piece yesterday about the “furore” among “independant” scientists over this.
As one comment from the linked article notes, there are flaws in every study. The rats fed GM corn developed more tumours, at a faster rate, than the control group. Bottom line.
Any study that uncovers problems with GMOs receives a firestorm of criticism. The scientists often lose their jobs:

Debunking the debunkers:

“The key is that there were both quantitative and qualitative differences in the tumours arising in control and test groups. In the former they appeared much later and at most there was one tumour per animal, if at all.
“In the latter case, the tumours began to be detected much earlier (4 months in males; 7 months in females), grew much faster and many animals had two or even three tumours.
“Many animals in the test groups had to be euthanised for welfare legal reasons due to the massive size of the tumours; none of the control animals had to be euthanised but died in their own time. One should not ignore these biological facts.”
