According to the National Statistics released data showed, in 2013, China’s total output of meat reached 85,350,000 tons, up 1.7% over the previous year. The mutton, because of its nutrient rich, the output reached 4,080,000 tons, a growth of 2.0% [1-2]. However, the meat was readily contaminated for microorganisms because of its high water content and abundance of essential nutrients, the environment and artificial factors also led to quality loss in process of livestock slaughter and processing.
