金华火腿晾晒过程中几种常见致病菌的检测

对金华火腿加工初期进行了常见致病菌的检测,包括大肠菌群、金黄色葡萄球菌及沙门氏菌。结果表明,金华火腿生产初期表面的菌落总数达105～106cfu/g,大肠菌群阴性,金黄色葡萄球菌阴性,分离到的葡萄球菌有施氏葡萄球菌(S.schleiferi)、人葡萄球菌(S.hominis)、表皮葡萄球菌(S.epidermidis)和解酪葡萄球菌(S.caseolyticus)。在刚浸泡洗刷好的火腿及晾晒1d的火腿上都检测到沙门氏菌的存在,而在晾晒7d的火腿上沙门氏菌阴性。

The object of this study was to detect some common pathogens including Coliform bacteria, Staphylococcus aureus, Salmonella during the sun shining drying stage of Jinhua ham. The results indicated that the aerobic bacterial count was between 105 and 106cfu/g, the Coliform bacteria and Staphylococcus aureus were negative. The Staphylococcus separated from the hams were S. chleiferi, S.hominis, S.epidermidis and S.caseolyticus. Salmonella was found on the washed hams （0 day） and 1 day-sun shining hams, but on 7 days-sun shining hams were negative. The results of the examination suggest that the hygiene in the Jinhua ham processing still need to be improved.
