摘要

從2000年至2002年分別至18、31、29家豬隻屠宰場，採集屠體表面擦拭檢體，檢測指標性微生物及病原性微生物。三年來所得盛行率的結果如下：好氧總生菌數為100%、100%、100%。大腸桿菌群為98.2%、98.0%、95.6%。大腸桿菌為96.7%、93.0%、85.1%。金黃色葡萄球菌為9.4%、7.4%、8.2%。產氣莢膜梭菌為1.5%、1.4%、1.4%空腸／大腸彎曲菌為28.4%、26.1%、21.5%，單核細胞增生李斯特菌為0.9%、4.9%、0.7%。沙門氏菌屬為8.5%、3.7%、2.9%。三年來都沒有分離到O157:H7型大腸桿菌。大腸桿菌群、大腸桿菌、產氣莢膜梭菌、空腸／大腸彎曲菌、以及沙門氏菌屬的盛行率三年來有逐步降低趨勢，空腸／大腸彎曲菌。單核細胞增生李斯特氏菌、以及產氣莢膜梭菌，每平方公分屠體面積所含有的平均細菌濃度，三年來有逐漸降低情形。本研究所得之結果希冀能做為國家訂定國內屠宰場衛生標準及衛生管理措施之參考，亦可做為屠宰衛生管理措施之成果評估依據。

From 2000 to 2002, we took swab samples from the body surface of pork carcasses in 18, 31, and 29 slaughterhouses, respectively, and investigated the prevalence of both indicator and pathogenic microorganisms. The results of the pre valence for these microorganisms were as follows, listed respectively to 2000.2001, and 2002: the aerobic plate count were 100% in all 3 years; total coliforms were 98.2%, 98.0% and 95.6%; Escherichia coli were 96.7%. 93.0% and 85.1%: Staphylococcus aureus were 9.4%, 7.4%, and 8.2%; Clostridium perfringens were 1.5%, 1.4%, and 1.4%; Campylobacter jejuni/ coli were 28.4%, 26.1%, and 21.5%; Listeria monocytogenes were 0.9%, 4.9% and 0.7%; Salmonella species were 8.5%, 3.7% and 2.9%. No E. coli 0157: H7 was isolated during the study period. There was a trend towards a gradual decrease in the annual incidence of total coliforms, E. coli. Clostridium perfringens, Campylobaeter jejuni/ coli, and Salmonella species. A trend towards a gradual decrease in the mean level of pathogenic microorganisms per square centimeter of carcass surface was found in C. jejuniI/ coli, L. monocytogenes, and C. perfringens. The findings of t his study may provide a reference for establishing hygienic standards and management of domestic slaughterhouses, as well as a criterion for evaluating the effects of slaughtering operation.
