2010～2016年云南省肉类制品致病菌污染状况调查

Investigation of pathogenic bacteria in meat products in Yunnan province from 2010 to 2016

目的了解云南省2010～2016年肉类制品中单核细胞增生李斯特氏菌、金黄色葡萄球菌和沙门氏菌的污染状况,为预防和控制食源性疾病提供基础数据和科学依据。方法 2010～2016年,在云南省采集3022件肉类制品样品,对单核细胞增生李斯特氏菌、金黄色葡萄球菌和沙门氏菌污染状况进行监测。结果 3022件肉类制品中共检出阳性致病菌312株,总检出率为10.32%,金黄色葡萄球菌、单核细胞增生李斯特氏菌、沙门氏菌的检出率依次为4.96%、3.97%、1.39%;散装样品致病菌检出率(11.60%)高于预包装样品致病菌检出率(7.06%);餐饮环节致病菌检出率(11.85%)与流通环节致病菌检出率(10.08%)无显著性差别。结论 2010～2016年云南省肉类制品中李斯特氏菌、金黄色葡萄球菌污染较沙门氏菌严重,应加强肉类制品在贮存、运输过程中的监督管理。

Objective To investigate the pollution status of Listeriamonocytogenes, Staphylococcus aureus and Salmonella in meat products in Yunnan province from 2010 to 2016, in order to provide basic date and scientific basis for the prevention and control of foodborne diseases. Methods Total of 3022 samples of meat products were collected and analyzed for the occurrence of Listeriamonocytogenes, Staphylococcus aureus and Salmonella in Yunnan province from 2010 to 2016. Results A total of 312 strains pathogenic bacteria were found in 3022 meat samples, and the total positive rate was 10.32%. The positive rates of Listeriamonocytogenes, Staphylococcus aureus and Salmonella were 4.96%, 3.97%, 1.39%, respectively. The positive rate of loose-packed（11.60%） samples was higher than which was prepackaged（7.06%）, and there were no difference between catering service（11.85%） and intermediate link（10.08%） in the positive rate of samples. Conclusion The pollution of Listeriamonocytogenes, Staphylococcus aureus is worse than Salmonella in the meat products in Yunnan province from 2010 to 2016, so we should strengthen the supervision and management of meat products during storage and transportation.
