[Safety evaluation of food from transgenic fish and the molecular biological mechanism]

More progresses have been made in the studying of transgenic fish in China, but the studying work of safety evaluation of food from transgenic fish are started up just now. Compared to plants and animals on the land, it is more difficult to control the mobility of fish and fish can give birth to a large number of offsprings, so the ecological risk or hazard about transgenic fish is more critical than others. Another safety problem is the chimerism which is initiated by the gene transfer methods used in the transgenic fish. Getting sterile triploid transgenic fish and fixed point integration are efficient to solve the two problems above respectively. The solution of the two problems are also the basis of safety evaluation and detection of food from transgenic fish. Up to now, there are little reports on the safety evaluation of transgenic fish including nutritional evaluation and allergic reaction, and there are no basic research on the detection of transgenic fish for the aim of food safety. In brief, it is very urgent to start up the research on the safety evaluation and detection of transgenic fish for the control of food safety.
