Abstract Chilled pork packaged in vacuum -packaging, CO-MAP (CO+CO2+N2) package, high-oxygen-MAP (high concentration of O2+CO2+N2) and low-oxygen-MAP (low concentration of O2+CO2+N2) were storaged at(4±1℃) for three weeks.The changes of microorganism were measured weekly. The results showed that: 1) lactic acid bacteria was dominant microorganisms in CO-MAP and vacuum packed (VP)in the end of storage. For the oxygen modified atmosphere packaging Pseudomonas was the dominant bacteria. 2) CO-MAP group could inhibit spoilage bacterial growth but had weak influence on lactic acid bacteria, had a strong inhibitory effect on Pseudomonas, Enterobacteriaceae bacteria all, its inhibition of spoilage bacteria significantly better than a vacuum packing group.
