People have two main concerns about genetically modified organisms and genetically modified foods. One is whether they are harmful to human health, and the other is whether they pose a potential threat to the ecological environment.

For the human body, certain gene transfers may produce new toxins and allergens, causing unexpected poisoning or allergic reactions. For example, some scientists have discovered that genetically modified foods can enlarge the liver; British scientist Pustoy conducted an experiment in which mice were continuously fed genetically modified potatoes and found that some mice had kidneys and spleens. Organs such as the brain shrink or develop abnormally, the immune system weakens, and so on.

Since the 1980s, genetic engineering technology has made breakthrough progress in the field of biotechnology. Through the artificial manipulation of biological genetic information, the biological characteristics of plants, animals and microorganisms can be changed. The use of genetic engineering technology can break the natural isolation barriers between biological species for artificial transfer. New genetic engineering entities are emerging. Keep coming out. This new development trend, on the one hand, shows the huge application prospects of advanced science and technology in production, on the other hand, it also indicates that it may bring adverse effects to other human body health and ecological environment. For this purpose, with the rapid development of biotechnology, it is both necessary and urgent to strengthen the safety management of genetic engineering work accordingly. The general principle of safety management of agricultural biogenetic engineering is that it should not only promote the development of genetic engineering technology, but also actively strive to protect human health and the safety of the ecological environment. To this end, the Ministry of Agriculture invited dozens of famous professors and experts from June to October 1994, and finally completed the drafting of the "Implementation Measures for the Safety Management of Agricultural Biogenetic Engineering." After review and approval by the Standing Committee of the Ministry of Agriculture, it was issued by ministerial order in July 1996 and officially announced and implemented on November 8. As of May 1998, 86 applications for genetic engineering safety evaluation had been accepted. , approval and announcement. This will enable agricultural biogenetic engineering work to be based on laws and regulations, and implement safety management of relevant agricultural biogenetic engineering in agricultural and non-agricultural systems. With the development of the market economy, the implementation of the "China Agricultural Biogenetic Engineering Safety Management Implementation Measures" has strengthened the credibility of domestic agricultural biogenetic engineering entities and their products entering the international market. Experts call for the establishment of a genetically modified plant safety assessment center and related technical systems to provide scientific basis for safety research on genetically modified foods; strengthen publicity and education to the public to improve acceptance of genetically modified foods
