Abstract

Abstract: Both internal and external bacteria floras in fresh chilled pork were analyzed and identified using selective medium, and their changes during the whole storage period of 8 days were also studied. Brochothrix thermosphact, Pseudomonas, Lactic acid bacteria, two strains of Enterobacteriaceae and a Staphylococcus were identified. B. thermosphact was the dominating spoilage bacteria of pallet packaged chilled pork. During the whole storage, Pseudomonas and Enterobacteriaceae had obvious growth and the microbes inside pork revealed faster growth than that of outside part.

Key words: fresh chilled pork, spoilage microorganisms, change pattern, endogenous pollution, exogenous pollution
