这些天,很多人都吃离家会暴露食源性疾病。这项研究是为了测试一些即食食品的质量和安全使用标准化(RTE)食品微生物参数。共75个样本组成每个15“Beyeanet”,“Keyiwot”、“面”,“提波斯”和“通心粉”收集从五个食堂周围Wollega大学(吴)和负载不同细菌群体的分析。药敏测试为代表进行隔离使用Kirby-Bauer磁盘扩散法。均值(日志)计数的有氧嗜中温细菌(AMB)是在6.041 - -6.441的范围从“Keyiwot”最高。同样,意味着最高计数(日志)细菌内孢子,肠杆菌科,总大肠杆菌群(TCF),粪大肠杆菌群(自由现金流量)和金黄色葡萄球菌为4.923,4.998,3.893,3.815和3.692从“Beyeanet”,“提波斯”、“通心粉”,分别“Keyiwot”和“Beyeanet”。没有显著差异水平的污染在自助餐厅(p < 0.05)对AMB、肠杆菌科和TCF。共收集107个细菌分离株的食物样本被确定为10个属。大量的芽孢杆菌>金黄色葡萄>产碱杆菌属>不动杆菌>假单胞菌>气单胞菌属>大肠>微球菌>邻单胞菌属>柠檬酸杆菌属。但是,没有沙门氏菌和志贺氏杆菌种虫害识别。 Plesiomonas and Alcaligenes were resistant to gentamicin; Escherichia, Plesiomonas Citrobacter, and Alcaligenes were resistant to erythromycin; and Staphylococcus, Micrococcus and Acinetobacter were susceptible to ampicillin. The isolates were intolerant to ciprofloxacin; whereas 6 of the 10 genera were resistant to carbenicillin and oxacillin. In general, the bacterial load of RTE foods around WU was beyond the standard limit for consumption. Therefore, training for cafeteria owners and food handlers on how to handle RTE food can reduce the risk of contamination.
