摘要
目的了解山西省食源性致病菌的污染现状。方法按照2010年度《全国食源性致病菌监测工作手册》进行。结果 1 576份样品中共检出阳性菌株149株,检出率为9.45%,其中单核细胞增生李斯特氏菌、副溶血性弧菌污染比较严重,总检出率为9.50%和8.22%,金黄色葡萄球菌、阪崎肠杆菌和沙门氏菌的总检出率分别为3.02%、1.11%和0.87%。不同类别食品中致病菌的检出率差异较大,生肉中致病菌的检出率高居榜首为49.33%,主要污染菌为沙门氏菌、单核细胞增生李斯特氏菌;沙拉中致病菌的检出率为17.39%,主要污染菌为单核细胞增生李斯特氏菌、金黄色葡萄球菌;生食水产品中致病菌的检出率为16.94%,主要污染菌为单核细胞增生李斯特氏菌、副溶血性弧菌;熟肉制品中致病菌的检出率为9.84%,主要污染菌为单核细胞增生李斯特氏菌、金黄色葡萄球菌、沙门氏菌;中式凉拌菜中致病菌的检出率为8.89%,主要污染菌为金黄色葡萄球菌;鲜榨果汁中致病菌的检出率为6.67%,主要污染菌为金黄色葡萄球菌;鲜冻水产品中致病菌的检出率为5.00%,主要污染菌为副溶血性弧菌;婴幼儿配方粉/米粉/谷粉/豆奶粉中阪崎杆菌的检出率为1.11%。结论山西省多种食品均存在食源性致病菌不同程度的污染,应加大对散装食品、即食食品和生食水产品的监管。
Objective To investigate and identify the contamination of main foodborne pathogens in Shanxi province.Methods According to the standard operation procedures in the handbook of 2010 National Surveillance on Foodborne Pathogens.Results Among 1 576 food samples tested,149（9.45%） pathogenic strains were isolated.The positive rate for L.monocytogenes was the highest（9.50%）,followed by V.parahemolyticus（8.22%）,S.aureus（3.02%）,E.sakazakii（1.11%） and Salmonella（0.87%）.A high prevalence of foodborne pathogens was shown in meat（49.33%）,the main contaminating bacteria were Salmonella and L.monocytogenes,followed by salad（17.39%）,the main contaminating bacteria were L.monocytogenes and S.aureus;raw aquatic（16.94%）,the main contaminating bacteria were L.monocytogenes and V.parahemolyticus;cooked meat（9.84%）,the main contaminating bacteria were L.monocytogenes,S.aureus and Salmonella;Chinese salad（8.89%）,the main contaminating bacteria was S.aureus;fresh juice（6.67%）,the main contaminating bacteria was S.aureus;fresh and frozen aquatic products（5.00%）,the main contaminating bacteria was V.parahemolyticus.The detection rate was 1.11% for E.sakazaki in baby formula milk powder/rice noodles/valley powder/soy.Conclusion Foodborne pathogens were frequently found in retail foods in Shanxi,it was necessary to strengthen the monitoring of food.
