2002～2004年广西食品中单核细胞增生李斯特氏菌的监测

Surveillance for Listeria monocytogenes in foods in Guangxi,2002～2004

目的了解广西食品中单核细胞增生李斯特氏菌污染状况,构建食品中单核细胞增生李斯特氏菌污染数据库。方法在广西6个城市建立监测点,定期对6类食品进行采样,食品检验采用中国疾病预防控制中心营养与食品安全所统一的单核细胞增生李斯特氏菌检验方法进行检验。结果检测6类1276份食品样品,检出单核细胞增生李斯特氏菌(L.m)51株,检出率为4.00%。结论在广西食品中均不同程度受到L.m污染,尤以淡水产品、生畜禽肉、非定型包装熟肉污染严重。

Objective To understand the situation of Listeria monocytogenes contamination in foods and to establish a database for Listeria monocytogenes contamination in Guangxi.Methods In6inspecting sites,foods were periodically sampled and examined for presence of Listeria monocytogens according to guidelines instructed by the National Institute of Nutrition and Food Safety,Chinese Center for Disease Control and Prevention.Results Among1276samples from6foods,51(4.00%)Listeria monocytogenes isolates were identified.Conclusion Foods in Guangxi are contaminated by Listeria monocytogenes,particularly in fresh-water products,rawmeat and cooked meat.
