The French government issued a decree on the audit of genetically modified foods (GMOs), after it was found an association between cancer and GMOs. This can lead to a ban in the European Union genetically modified maize NK603.
Agriculture Minister Stephane Le Foll, Minister of Ecology Delfayn Bato and Health Minister Marisol Toureyn made a request for investigation to the National Agency of Health.
"The investigation of the agency, the government will decide on the necessary measures to protect human and animal health," - said in a joint statement.
Earlier, French scientists led by Gilles-Eric Zeralini from the University of Caen Lower Normandy, conducted a study in which mice were fed maize NK603 and tracked statistics of cancer.
Maize NK603 was developed by the American company notorious for the production of GMO Monsanto.
The corn has been bred to make it resistant to the herbicide developed by Monsanto under the name Roundup (glyphosate).
GMO crops are widely distributed in North America, Brazil and China. In Europe, around GMOs conducted a heated debate.
The study, published in the peer-reviewed journal Food and Chemical Toxicology, first studied mice throughout their normal life span of two years.
"For the first time in history, a study was conducted long-term health effects from the use of GMOs and herbicide application, and with much more faithfully than has been done by the government or corporations" - said Zeralini. "The results alarming."
Two hundred male and female mice were divided into groups of 10 animals each.
The researchers found that both NK603, and Roundup cause health problems similar mice, irrespective of whether they are consumed together or separately.
It was found that premature death and disease affects more females than males.
During the first 14 months of the experiment, animals fed on normal for their kind of food did not show symptoms of cancer, with 10-30% of those who used GMOs for growing Roundup-treated, suffering from cancer.
A request for comments, the French branch Monsanto said: "It is necessary to conduct peer review of the study. As soon as our experts will get access to this data, it will provide evidence-based comment."
The representative of Monsanto said, "more than 300 peer-reviewed studies" have certified the safety of genetically modified food.
Currently imports are allowed, but prohibited the cultivation of NK603 in Europe.
