Abstract

ARTICLE INFO A total of (120) sample of ready to eat (RTE) meat;(20) each of cooked luncheon, frankfurter, hot dog, pasterma, shawrma and smoked luncheon were collected from different shops and grocery stores in Beni-Suef City. To be examined for their microbial load for aerobic plate count (APC), most probable number (MPN) of coliforms, fecal coliforms and E.coli as well as Staphylococcus aureus and enterococci were enumerated. Additionally E.coli, salmonella and Listeria were isolated and identified biochemically. Aerobic plate count (APC) had the highest mean value in shawerma (1×10 7 ± 5×10 6 CFU/g), shawerma also showed the highest most probable number (MPN) of coliforms and fecal coliforms (11 and 6 CFU/g) mean while pasterma was the highest contaminated with Staphylococcus aureus (3×10 4 CFU/g) and the highest count of enterococci was detected in hot dog (3×10 5 CFU/g). On the other hand each of E.coli, Salmonella and Listeria species were failed to be detected in any of the examined samples. The public health significance as well as the recommendations to produce safe and high quality ready to eat (RTE) meat products were mentioned. Article history:

即食加工肉类的微生物风险评估

本文从贝尼-苏夫市的不同商店和杂货店收集了120份即食肉类样品，各20份熟食午餐、法兰克福香肠、热狗、意大利面奶酪、沙乌尔玛和烟熏午餐。对其好氧平板计数(APC)、大肠菌群、粪便大肠菌群、大肠杆菌以及金黄色葡萄球菌和肠球菌的最可能数量(MPN)进行计数。此外，对大肠杆菌、沙门氏菌和李斯特菌进行了生物化学分离鉴定。好氧平板计数(APC)均值最高的是沙尔玛(1×10 7±5×10 6 CFU/g)，大肠菌群和粪便大肠菌群的最可能数(MPN)均值最高的是沙尔玛(1×10 7±5×10 6 CFU/g)，金黄色葡萄球菌污染最高的是帕德马(3×10 4 CFU/g)，肠球菌污染最高的是热狗(3×10 5 CFU/g)。另一方面，大肠杆菌、沙门氏菌和李斯特菌均未在任何检测样本中检测到。会上提到了公共卫生的重要性以及生产安全和高质量即食肉制品的建议。文章历史:
