Abstract：The residents' risk perception of food safety plays a crucial role in individual consumption behavior, enterprise risk communication and government policy making. In this paper, the assessment system of food safety risk perception was built from the perspective of the residents' food safety knowledge, attitude and behavior. The data were obtained by means of network questionnaire, and some measures to enhance the residents' food safety risk perception were suggested based on the analysis of the samples' food safety risk perception. The results were: the food safety risk perception of samples was in the medium level, and the mean score was 66. 92; the score of knowledge about food safety was 78. 67, which indicated that the samples had a better knowledge of food safety; the score of attitude (72. 55) was lower than that of knowledge; The behavior was in the lowest level and its score was 49. 55; the behavior was the main factor that influences the residents' risk perception of food safety, and the attitude was the second main factor, while the knowledge was good; enhancing the public effective behavior to deal with food safety incidents was one of the most important measures to improve the residents' risk perception of food safety.
