Recently, the heilongjiang province soybean association is a genetically modified soybeans and tumor highly correlated analysis, lead to gm opponents and supporters of the "flame wars". , deputy director of the office of the national cancer prevention and control research Chen Wanqing professor said, there is no evidence to prove the existence of genetically modified food safety hidden trouble, also no large-scale population studies have confirmed its security --

Genetically modified (gm) "flame wars" refraction lack of scientific research

        Based on the analysis of soybean in heilongjiang province association deputy secretary-general Wang Xiaoyu, henan, hebei, gansu, qinghai, Shanghai, jiangsu, guangdong, fujian and other places, the basic is genetically modified soybean oil consumption focus areas in our country. According to the 2012 China cancer registration update shows that these areas are also cancer clusters in our country. Heilongjiang, liaoning, zhejiang, shandong, hunan, hubei, guizhou, basic not to consume genetically modified soybean oil is given priority to, the corresponding nor tumor incidence concentrated area.

        Said that Chen Wanqing, tumor is a multi-factor disease, with the genetically modified soybeans "derivative" together without scientific basis. Party will be the divided into genetically modified soybean oil consumption and low consumption, loopholes in itself. And genetically modified food is not only the soybean, genetically modified (gm) soy is not only exists in the form of soybean oil, soy products, snacks, etc are likely to have.

        Secondly, from the Angle of epidemiology analysis, identify cancer risk factors not only for simple comparison, multicenter, randomized, double-blind control study should be taken to strict statistical analysis method, etc. On the genetically modified food safety issue, ideally the prospectie cohort study method, random grouping, a set of people eat genetically modified food, a group of people eat genetically modified food, after long-term observation, and tumor incidence of statistical analysis.

        Third, the United States is China's early use of genetically modified food, but the overall incidence of cancer since the 90 s was a declining trend.

        In addition, there are media reports, in 2010 by the Russian national security association genes and Campbell hamsters study institute for ecological and environmental problems, the results show that gm foods will lose mammalian reproductive capacity. In September 2012, the French Kane university scientists, through a two-year classification study found that, of 200 mice with genetically modified (gm) maize "rr" NK603 and herbicides contaminated feed mice, likely to develop cancer and visceral injury.

        Chen Wanqing said, at present, both at home and abroad are lack of genetically modified food for the population health effects of large-scale research data, and cannot be copied on the human body and animal study. According to media reports, November 28, 2012, the European food safety authority is French "gm maize" cancer research issued a final conclusion, say the study is lack of scientific basis, in the process of risk assessment, design, reporting and analysis link are not enough scientific and rigorous.

        Chen Wanqing also say, however, the event should cause the attention of the public and related departments, for further consideration on the safety of genetically modified (gm) food and validated.

        Chen Wanqing pointed out that, although there is no evidence that genetically modified foods pose a safety hazard, but also no large-scale population research evidence, confirm their safety. Therefore, it is necessary to emerging products, such as genetically modified (gm) food into tumor risk factors analysis. "Even in the theoretically possible forward-looking statistics, also because of possible health risks of genetically modified food, but is limited by ethics, it is difficult to in real life. In the meantime, even by retrospective study, nor how much is per person per day to eat genetically modified foods' quantitative analysis. All these problems we need to further think and answer."
