湖北省食源性致病菌污染状况调查分析

目的 了解湖北省食品中食源性致病菌的污染状况及其趋势。方法从2000年开始对湖北省食品中食源性致病菌进行了监测。在9个监测点采集8类共2488份食品样品．按常规方法分离鉴定沙门氏菌．O157：H7。单增李斯特氏菌、弯曲菌、副溶血性弧菌。结果5种食源性致病菌在湖北9个地区都有污染存在，以沙门氏菌污染率最高（5．8％）。其次是单增李斯特氏菌（3．5％）。在监测的8类食品中，以生肉类食品污染率最高（20．3％）。而这类食品中又以生鸡肉污染最为突出（28．％）。结论湖北省食品中食源性致病菌污染趋势有明显上升。应引起有关部门的重视。

Food contamination by pathogenic bacteria in Hubei Province

Objective Surveillance was conducted in Hubei province since 2000.(Methods) To find out food contamination by pathogenic bacterium and its trend in our province.2 488 food(8 categories) samples were taken in 9 surveillance spots.Routine method was used to isolate and identify Salmonella,E.coli O157,Listeria,Camplobacter,and Vibrio parahaemolyticus.(Results) The 6-year investigation showed that there were food contamination by all the five pathogenic bacteria,among them,Salmonella contamination was the highest(5.8%),followed by Listeria(3.8%).Of the eight types of food,the heaviest contamination was caused by uncooked meat (20.3%),especially uncooked chicken(28.0%).Conclusion The 6year surveillance suggests that food contamination by pathogenic bacteria in Hubei is significantly increasing and calls for more attention by concerned departments.
