Abstract:

Since the large-scale commercialized production of genetically modified (GM) crops started in 1996, it has
brought great socioeconomic benefits to human beings. Yet transgenic technology may give rise to certain risks, so it is
urgent and important to strengthen the safety assessment and standard management of GM foods. In this paper, the safety
evaluation contents of GM foods are summarized, including nutrition, toxicity, allergenicity, etc. What’s more, the key issues
of transgenic food safety evaluation, including different animal studies conducted to evaluate the safety of GM foods, food
safety assessment of new types of transgenic plants and safety standardization of GM foods, are discussed from different
perspectives. The target of this paper is to enable the readers to have a more comprehensive understanding of food safety of
GM foods.

Key words: genetically modified food, safety assessment, animal study, transgenic plant, safety standardization
