The invention relates to a whole process tracking and tracing method and 
system thereof for 
quality safety of beef products, which belongs to 
digitization category of beef product 
quality safety. The invention adopts a 134.2 KHz electronic 
ear tag to mark individual cattle in 
beef cattle breeding period and a breeding management 
subroutine to 
record the situation of immunization, epidemic prevention and feeding diseases, in 
beef cattle breeding period; in butchering period, the 
system realizes the transformation from a breeding 
ear tag to a new 
ear tag; hooks on a butchering line are provided with 915M electronic labels, when weighing carcasses, number and types of inspection labels as well as 'new ear tag No.' are written on corresponding labels on hooks; when the carcasses are sent from an acid 
discharge storehouse to a 
cut line, the 
system realizes the transformation from the 915M electronic 
label to a bar code and automatically delivers data to an electric balance by a UDP protocol in 
wireless mode to realize the organic integration of management, control and production through printing program by an embedded bar code. The invention compactly combines 
software, hardware, the electronic 
label with low or 
high frequency, the bar code, and system management 
software to realize the seamless integration of production operation and marking management, thus greatly improving working efficiency.
