The food traceability system has been positively implemented in China to enhance the food safety level for decades. The food traceability system was first built on pork which has high food safety risk and high consumption by consumers in China. The Chinese food traceability system between different enterprises or different areas are not compatible by using different traceability standards，which severely inhibited the food traceability system to prevent food safety risk. Until 2012，the Ministry of Commerce in China has issued a series industry standards and rules to guide the construction of meat and vegetable circulation traceability system. They want to unify the traceable standard between different areas and different corporations. This paper takes China’s biggest pig slaughter and processing enterprises—Nanjing pig slaughter and processing enterprise H as an example，and studies its own standards and pork traceability system procedure. The results show that there are significant differences between the pork traceability system standard of H enterprises and industry standard in information acquisition，information storage，tracking code，and information processing and transfer method. Accordingly，three reasons were summarized why pig slaughter and processing enterprise do not use pork traceability industry，and put forward corresponding countermeasures and suggestions about how to induce big pig slaughter and processing enterprise unify their pork traceable standard with industry pork traceable standard to lead and promote the implement of food traceability system in China.
