Abstract: As effective methods of quality security management, traceability system for meat food would attract the attention of consumers, domestic and foreign agencies. This paper determined the traceable fuzzy prior probability and distribution function based on the hazard risk severity, frequency and measured, actualized the tracking and early-warning of quality security combining to the expertise and knowledge, established direct and indirect traceable negative correlation set of the quality security according to the previous hazards results, recognized risk model and factors of minimal cut sets and minimal path sets for the quality security of meat food based FMECA, and achieved the traceability of quality security.

Key words: meat food, traceability system, fuzzy evaluation, FMECA
