我国零售食品单增李斯特菌污染的健康风险分级研究

目的对我国零售阶段食品中单增李斯特菌污染的健康风险进行评估和分级。方法利用全国污染物监测网中2010—2013年食品中单增李斯特菌污染水平监测数据、2002年中国居民营养与健康状况调查中的膳食消费量数据以及2011年中国统计年鉴资料,对李斯特菌病敏感人群通过5大类17小类食品暴露于单增李斯特菌的风险进行评估和分级。结果生食水产品是单增李斯特菌污染水平较高的食品类别,其次是散装熟肉制品。豆腐皮/丝是导致李斯特菌病每年发病风险最高的食品,散装熟肉食品导致的单增李斯特菌健康风险是定型包装的4~10倍。结论生食水产品和散装熟肉制品导致的每餐单增李斯特菌病发病风险最高,即食非发酵豆制品和熟肉制品是可能导致我国每年发生单增李斯特菌病的最主要食品。

Risk ranking of Listeria monocytogenes contaminated ready-to-eat foods at retail for sensitive population in China

Evaluate relative risk of listeriosis for sensitive population in China among selected categories of ready-to-eat foods at retail.Methods Relative risk for per serving and per annum of 5 major kinds, 17 categories ready-to-eat food were estimated by using food contamination data of Listeria monocytogenes during 2010-2013 from National Surveillance Network, consumption data from Chinese National Nutrition and Health Survey in 2002, and number of population from China Statistical Yearbook in 2011. Results Ready-to-eat raw fish has the highest per serving risk of listeriosis among all the selected food categories, and loose packaged meat products also have very high risk. Ready-to-eat bean curd skin has the highest per annum risk among all the food categories. For same category of meat products, risk of listeriosis for loose packaged products was 4-10 times higher than the prepackaged ones.Conclusion Ready-to-eat raw fish and loose packaged meat products have relatively higher per serving risk of listeriosis for sensitive population and ready-to-eat bean curd skin has relatively higher per annum risk of listeriosis.
