Genetically modified components (10.31) were first detected from imported rapeseed in China

OA show ('918 '); it is reported that recently, the Shanghai entry exit inspection and epidemic Bureau has detected genetically modified ingredients from a batch of imported rapeseed from Canada, which is the first time in China At present, there are still disputes on the safety of genetically modified agricultural products in the world At the same time, because most of the genetically modified agricultural products have the characteristics of high yield, disease and insect resistance, the production cost is greatly reduced, and compared with ordinary agricultural products, they have more price advantages in trade negotiations Therefore, the relevant international conventions stipulate that the export of genetically modified agricultural products should be labeled with the identification label, so that the buyer can choose freely In recent years, Shanghai port has imported about 1 million tons of rapeseed every year, but none of them have been labeled with transgenic It is the first time for Shanghai to detect genetically modified ingredients from imported rapeseed, which indicates that China's inspection and quarantine technology level has been improved This will promote the producers and traders of relevant overseas products to actively label in the future, which is of great significance to maintain the fair trade order and regulate the market access of genetically modified agricultural products According to Chen Jiahua, an expert in charge of animal and plant inspection and quarantine and food inspection and Quarantine of Shanghai entry exit inspection and Quarantine Bureau, rapeseed is the most difficult category in the genetically modified detection of agricultural products because of its high oil content and the difficulty in extracting pure and high-quality total DNA In addition, the promoter, termination and kanamycin resistance screening genes were also detected It is understood that although the application of genetically modified technology in agriculture is still in its infancy, its development is very rapid The planting area of genetically modified crops in the world has increased from 2 million hectares in 196 to 40 million hectares last year, of which the planting area of genetically modified crops in the United States, Argentina and Canada accounts for 99% of the world's total Half of the planting areas of major crops in these three countries, such as soybeans and corn, use genetically modified seeds Therefore, it is imperative to strengthen the transgenic detection of imported agricultural products It is understood that at the beginning of last year, genetically modified ingredients were detected from imported rice for the first time in China, which was also completed by Shanghai entry exit inspection and Quarantine Bureau Since this year, in order to adapt to the new situation of scientific and technological progress and the development of import and export trade, the Bureau has set up a genetically modified testing laboratory and carried out a series of cutting-edge research on the testing methods of imported genetically modified soybeans and rapeseed China feed industry information network FBZ (author:)
