Genetically modified microorganism （GMM）， also known as recombinant DNA microorganism， means a micro-organism in which the genetic material has been altered in a way that does not occur naturally by mating and/or natural recombination. Given the fact that the safety management requirements for GMM and related products used in food industry differ among countries， different countries adopt different regulations. Chinese government attaches great importance to the management of GMM and related products used in food industry， and has successively issued a series of administrative regulations， departmental rules， announcements， and standards. This study systematically reviews the safety management requirements from international organizations and Western countries for GMM and related products used in food industry， and provides reference and experience for the management of relevant risks in China.
