Aiming at the frequent occurrence of food safety incidents in recent years，statistics and analysis of food safety incidents from two aspects of time factors and regional distribution are put forward，explore the hidden internal laws，so that people have a better understanding of food safety incidents，provide sufficient and reliable data support for the departments concerned to make effective prevention and timely response to food safety incidents. First，the food safety data were preprocessed to build a time naming entity for food safety emergencies. The time expression is identified with the conditional random field model. From the perspective of time change of food safety events in various regions，the trend map of event occurrence in high incidence area is drawn and analyzed，and the probability of future events is predicted according to the trend map. Then，in the area distribution，the probability distribution of food safety emergencies in each region is counted and analyzed from two angles of the single region and the multi region. The single region includes three indexes：frequency，density and breadth and the multi region include co occurrence frequency，co occurrence breadth，point mutual information and conditional probability. The results show that the statistics and analysis of two aspects of the time factors and regional distribution of food safety events can effectively grasp the law of food safety events and predict the future trend，and provide reliable support for the prevention，prediction and early warning of food safety emergencies.
