Abstract:

The establishment of quality safety traceability system for beef cattle and its cutting products is an important technical means to meet the consumers right to know, to choose and to realize the government supervision. Considering beef cattles are mainly scatter feeding in China,  the traceability for main responsibility is particularly important. Therefore, farm or farmer information code was added to beef individual 15 bit code. This code was not only compatible with the 67 orders by Ministry of Agriculture, but also gave a new definition to the laler 8 coding bits. In addition, the electronic identification, first coding and the database to record the association relationship between electronic identification codes and cattle are effective coding and marking methods for large-scale cattle farms. For  beef products identification, the European Logistics coding rules of EAN·UCC 32 bar code was adopted, which could meet the requirement for beef product entering the international logistics market, or use the user-defined 22 bit terminal division code (beef product sourcing code). In conclusion, beef end products could be reverse traced to the slaughtering and feeding stage by the establishment of the bridge between computer system and slaughtered cattle individuals or subgroups through product sourcing code.
