Abstract: Up to now,no countries allow commercialization of genetically modified(GM) rice concerning food and environment safety problems,even if the development of GM rice has matured. Whereas,transgenic rice has been found on our market,so it is urgent to develop food safety assessment methods of GM rice and related criterions to regulate the commercialization and production of GM rice. This article reviewed food safety assessment studies of transgenic rice,including substantial equivalence of nutrition,nutritional assessment on animals,in vivo and in vitro toxicology studies,allergenicity assessment and horizontal transformation of introduced gene,in order to provide reference for further food safety assessment work and foundation of criterion system.

Key words: genetically modified rice, food safety
