摘　　要：目的了解石家庄市肉毒梭菌在环境中的分布情况,为预防、诊断、治疗肉毒梭菌食物中毒提供科学依据。方法按照地貌,均匀抽取8个县(市、区),采集土壤、食品和水3类样品,检测肉毒梭菌污染情况。结果采集土壤、水、食品3类样品共350份,肉毒梭菌检出15份,检出率为4.3%,其中,12份为B型肉毒毒素,3份为A型肉毒毒素。发生过肉毒中毒的县(市、区)肉毒梭菌检出率高于未发生过的县(市、区)(P<0.05)。山区与平原肉毒梭菌检出率差异无统计学意义。结论石家庄市外环境中肉毒梭菌污染较以前严重,并且存在A型肉毒毒素。Objective To explore the distribution of Clostridium botulinum in environment,so as to provide scientific basis for the prevention,diagnosis and treatment of food borne botulism in Shijiazhuang district. Method According to the landform,350 soil,water and food samples from 8 areas of Shijiazhuang were evenly collected for testing Clostridium botulinum. Results Clostridium botulinum was detected in 15 samples （ 4. 3% ）. Type B Clostridium botulinum was detected in 12 samples,and type A Clostridium botulinum was detected in 3 samples. The contamination rates in areas where food borne botulism have occurred were higher than areas where no food borne botulism have occurred （P 0. 05）. The contamination rates between mountainous and plain areas was not significantly different. Conclusion The prevalence of Clostridium botulinum in Shijiazhuang district was higher than before,and type A Clostridium botulinum is present in these areas.
