Abstract: Aiming at the existing requirements of animal husbandry production quality safe in China, architecture of pork production information traceability system was studied in this paper. Based on European Article Numbering (EAN) and international logistics information label, requirements analysis and architecture analysis of pork production information traceability were presented. A whole process traceability system that could be applied in pork production with Chinese situation was created. The contents of traceability information and individual marking were analyzed. On this basis, the style and model of logistics unit mark and label that used in pork production supply chain were designed. The structure of hardware and software were presented. With the structure, a pre-warning system was developed, which could be applicable to the pork production traceability system. The instance analysis shows that the proposed traceability system could effectively identify the security problem in pork production, and issue the recall information. Based on the integrated and robust traceability data, the logistics information and production streams were systematically contracted. Every supply chain member and consumer could acquire the complete pork production information in this system. The system for pork production supply chain performed well and effectively.
