Abstract: Rice is one of the major food crops for humans.It is also an important feed source of animals.In recent years,several transgenic Bacillus thuringiensis (Bt) rice were bred by domestic and international research institutes.These varieties of transgenic Bt rice can kill insect pests such as rice stem borer,yellow rice borer and rice leaf roller.They can also reduce the use of pesticides and boost rice yields.People pay much attention to safety of transgenic Bt rice as it is one of the major food crops.As yet there is no definite evidence that the transgenic Bt rice has safety issues.But we still need to monitor the results of long-term consumption of the rice continuously.This article mainly reviews the development,potential risk and safety assessment method,nutritional value and toxicity of transgenic Bt rice,the impact of growth and immune of animals,the foreign gene and the foreign protein in vivo residual.

Key words: transgenic Bt rice; nutritional value; growth; immune; foreign gene; residual
