According to the latest data from the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ), from October 2013 to the present, more than one million tons of imported corn from the United States have been returned due to the detection of MIR162 genetically modified components that have not been approved by the Ministry of Agriculture of the People's Republic of China. What is the use of genetically modified corn? Is it safe to eat? To this end, the reporter visited relevant officials and authorities of the Chinese Ministry of Agriculture, the United States Department of Agriculture, and the Chinese Academy of Agricultural Sciences. Luo Yunbo, Dean of the College of Food Science and Nutritional Engineering of China Agricultural University, told reporters that currently, genetically modified corn is basically used for feed processing, and basically, the market can not buy fresh corn. "One is that imports have strict regulatory oversight, and the second is that corn varieties are very specialized. The corn used as a feed is taken to squeeze oil or fresh food. Both taste and price are uneconomical." Although the State stipulates that GM corn cannot be used for fresh food, GM rice must not be grown for sale, but it cannot be ruled out that some genetically modified foods have been abused or flowed into the market but they have not been labelled as required. A paper from the Shenzhen Municipal Center for Disease Control and Prevention in 2012 showed that the center had purchased 26 soybeans and 80 soy products on the market for testing and found that the two samples were genetically positive and not labeled. According to Peng Yufa, a researcher at the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences, prior to the 1990s, genetic modification at the time lacked safety assessments and regulations, leading to the outflow of some seeds. "The case of rice is a matter of history. If the seed is polluted, it may not be clean for many years." (According to Xinhua News Agency, Shanghai, May 14)
