Objective To study the application of hazard analysis and critical control(HACCP) practice to food safety management during significant missions by the Armed Police Forces. Methods According to the field practices of significant activities and the basic principles of HACCP, all the risk factors throughout the food preparation process were analyzed to define critical control points（CCP）at which these risk factors can be controlled. Results Hazard analysis confirmed that recipes, raw material purchase, food processing, food distribution, food detection, tableware cleaning and disinfection, and personnel health were 7 critical points for food preparation. Conclusion The application of HACCP to food processing during important activities not only reduces the risk for food safety, improves the management level but helps gain experience on food safety.
