Recently, the French scientist Seralini said that the two-year test results showed that genetically modified corn induced tumors. The Yangcheng Evening News reporter learned that - this year, imports of corn or up to 7.2 million tons of about eight to become genetically modified

On one hand, foreign media reported that China Reserve Grains ordered 960,000 tons of U.S. GM corn last week, setting a record for domestic corn import orders for at least two years; on the other hand, operators of the “GM corn carcinogenic” trial officially responded Questioning, once again saying that it broke the 90-day limit of genetically modified trials, found that the rats that were fed the NK603 transgenic corn with herbicide resistance had a high carcinogenic rate and said that the transgene would certainly affect the liver, kidney and breast. A reporter from the Yangcheng Evening News yesterday found that most of the corn sold on the market was not labeled with genetic modification, and several brands of edible corn oil were clearly labeled.

French scientists approve genetically modified corn

According to the “Daily Economic News” report, Séralini, the operator of the “Carcinogenicity of GM corn-causing mice” trial, repudiated doubters again when he attended the International Symposium on Genetics and Food Safety in Beijing. In September 2012, French scientist Seralini and his colleagues published an article in the "Food and Chemical Toxicology" that showed high carcinogenic rate in rats fed with herbicide-resistant NK603 genetically modified corn. Tumor. Subsequently, the conclusion of the test quickly encountered numerous questions. The Dean of the French National Institute of Agricultural Sciences pointed out that this study lacks sufficient statistical data, and that its experimental methods, data analysis and conclusions are all flawed. More open risk-benefit analysis should be conducted for genetically modified crops to develop more cross-cutting Research on genetically modified crops in the discipline, with particular emphasis on its long-term effects on animals and humans.

In this regard, Séralini retorted that at present, the GM trial has a provision that 90-day mammalian trials prove safe to be eaten, but its team broke the 90-day boundary for the first time in the world — two years . Séralini said: “We can see that in the two-year period, 34 organs of 50 rats have been enlarged. We have done experiments on 200 mice... Our conclusion is that genetically modified liver, kidney, and breasts It will definitely have an impact and it is insecure. We must stop using it."

No corn marked with genetically modified corn in the market

The Ministry of Agriculture stated that at present, after being reviewed by the National Commission for the Safety of Agricultural Genetically Modified Organisms, it has successively approved the import safety certificates for four genetically modified crops, including genetically modified maize. The information released by the Ministry of Agriculture of China recently showed that last year the varieties of genetically modified corn from Monsanto, Pioneer International, Syngenta and many other companies were approved by the Ministry of Agriculture for import, and their uses were "used as raw materials." Previously, large companies such as COFCO and New Hope have imported genetically modified corn from abroad.

The reporter visited the market yesterday and found that none of the corn sold in the farmer's market was labeled with genetically modified products. Some stall owners told reporters that they are not aware of whether they are genetically modified products. At China Resources Vanguard Supermarket, the reporter found that Fortunegate, Golden Arowana, and Longevity Flower gold embryo corn oil were all specifically labeled as “non-genetically modified crush”. In the blended oil, the multi-vitat sunflower blend oil marked its five raw materials, sunflower seeds, corn, sesame seeds, peanuts, and flax seeds are all non-genetically modified raw materials. The Golden Arowana II blended edible oil, Fook Lam Mun natural cereal blended oil, and gourmet customers only indicated raw soybeans and rapeseed as genetically modified.

In response, Xu Xiaomiao, corn analyst at Zhuo Chuang Information Technology, told the Yangcheng Evening News that 99% of the corn imported from the United States is genetically modified, but domestic corn oil is currently basically produced by domestic maize crushing. The level of genetic modification of domestic corn is still not obvious. of. According to MSG manufacturers that use corn as raw materials, they cannot use imported corn to process food products. The main purpose of importing GM corn is to make feed. The Ministry of Agriculture also stated that except for the approval of the cultivation of genetically modified cotton, the use of other crops, including genetically modified corn, is limited to the processing of raw materials. According to the Ministry of Agriculture, China has not approved the import of seeds of any genetically modified food crops into China. Therefore, it is unlikely that GM corn will be seen on the market.

Is GM corn safe for feed?

Although the market did not see corn and its products clearly labeled as genetically modified, the growth of genetically modified corn has become overwhelming.

According to a report issued by ISAAA, the global acreage of genetically modified crops reached approximately 170 million hectares in 2012, a 6% increase from 2011. According to the planting area statistics, about 35% of the world's corn is a genetically modified product. According to the data provided by Zhuo Chuang Information, in 2006-2010, China imported between 350,000 and 800,000 tons of corn each year. However, since 2010, imports of corn have started to grow by leaps and bounds. It reached 1.57 million tons in 2010/2011, and 1.75 million tons in 2011/2012, and 5.21 million tons in 2012/2013. Some industry insiders even predict that China's imports this year may reach the import quota limit of 7.2 million tons. Xu Xiaomiao said that about 90% of corn imported from China comes from the United States, and about nine of them are genetically modified corn. That is, about eight percent of the imported corn has become genetically modified corn.

According to the requirements of the National Development and Reform Commission, genetically modified corn can only be used for feed processing, and it can be completely closed. It is forbidden to circulate the raw grains in the market.

In response, industry insiders who did not want to reveal their identities stated that the problems reflected in the Selalini test had to be taken seriously. At home, the main use of the current GM corn is animal feed, which is temporarily not allowed to grow. However, if it is considered that planting and eating are not safe enough, it is difficult to guarantee that animal feed will not be harmful to animals and humans; in addition, Séralini's test also raises a problem that the 90-day test period previously considered in the industry does not The question of whether it can ensure that animals in the real world can eat for more than 90 days is not a problem. The person said that the relevant authorities must explain this.
