摘要:

产气荚膜梭菌(C. perfringens)在自然界广泛分布,在鸡、鸭、猪、牛等食源动物中均普遍流行。生肉及其制品在加工过程中可能被产气荚膜梭菌污染而引起人的食源性腹泻,而且越来越多的证据表明产气荚膜梭菌出现了多种耐药性,因此控制产气荚膜梭菌污染具有重要的公共卫生意义。本文从该病流行、毒素、耐药基因、屠宰零售及食品污染风险等各环节进行梳理,分析该病引起的公共卫生危害,并提出了相关的控制建议。

Abstract:

Clostridium perfringens(C. perfringens) is widely distributed in nature, and is epidemic among food animals such as chicken, duck, pig, cattle etc. The pollution of raw meat and its products by C. perfringens during the processing may cause food-borne diarrhea in humans. In addition, more and more evidence suggested that the bacteria has developed multi-drug resistance. Therefore, the control of C. perfringens pollution has important public health significance. This paper reviewed the public health hazards caused by the bacteria based on the epidemic situation, toxin , drug resistance gene, slaughtering retail and food contamination risk,and putted forward relevant control suggestions.
