For the human body, a certain gene transfer may produce new toxins and allergens, causing unexpected poisoning or allergic reactions. For example, some scientists have found that genetically modified foods can make the liver bigger; British scientist Pusztai continuously fed genetically modified potatoes to mice and found some kidneys and spleens. Abnormal contraction or development of organs such as the brain, weakened immune system and so on.
Since 1980s, genetic engineering technology has made a breakthrough in the field of biotechnology. Through the manual manipulation of biological genetic information, the biological characteristics of plants, animals and microorganisms are changed, and various genetic engineering technologies can break the natural isolation barrier between biological species for manual transfer, and new genetic engineering bodies are constantly coming out. This new development trend, on the one hand, shows the great application prospect of advanced science and technology in production, on the other hand, it also indicates that it may bring other health benefits to human body and adversely affect the ecological environment. Therefore, with the rapid development of biotechnology, it is necessary and urgent to strengthen the safety management of genetic engineering accordingly. The general principle of safety management of agricultural bio-genetic engineering is not only to promote the development of genetic engineering technology, but also to actively protect human health and ecological environment. Therefore, the Ministry of Agriculture invited dozens of famous professors and experts from1June, 1994 to1June, and finally completed the drafting task of "Implementation Measures for Safety Management of Agricultural Biogenetic Engineering". It was deliberated and adopted by the executive meeting of the Ministry of Agriculture, and was promulgated by ministerial decree 1996 in July 2006, and was officially promulgated on10.8. By May, 1998, * * had accepted 86 applications for safety evaluation of genetic engineering, which were approved and promulgated after safety evaluation. Make the work of agricultural bio-genetic engineering have laws to follow and rules to follow, and realize the safety management of agricultural bio-genetic engineering in agricultural system and non-agricultural system. With the development of market economy, the implementation of "Implementation Measures for Safety Management of Agricultural Bio-genetic Engineering in China" has enhanced the credibility of domestic agricultural bio-genetic engineering and its products entering the international market. Experts call for the establishment of a safety evaluation center for genetically modified plants and related technical systems to provide scientific basis for the safety research of genetically modified foods; Strengthen publicity and education for the public to improve the acceptability of genetically modified foods.
