Abstract

The study was designed to assess the safety and bacteriological quality of one hundred and twenty samples including (small scale fluid cream, large scale Laban rayeb, Pasteurized milk and UHT milk) (30 of each). The samples were collected randomly in their retail packages from different localities in Fayoum province, Egypt. Samples were analyzed for total bacterial count (TBC), total coliforms, fecal coliforms, Escherichia coli and Staphylococcus aureus. The mean value of TBC in small scale fluid cream and pasteurized milk were 1.68×106 ± 1.3×105 and 4.30×103 ±6.66×102 CFU / ml respectively. The mean value of Faecal coliforms in Fluid cream were 1.87×104 ± 8.18×103 CFU / ml. E. coli only present in fluid cream with a mean value of 2.25×103 ± 8.63×102 CFU / ml. Isolated E. coli strains were serologically identified as O125(16/30), O158 (10/30), O1 (4/30) with a percentage of 53.33%, 33.33 and 13.33% respectively. By using conventional PCR, E. coli were harbored aroA and fimH genes and not harbored STx1 and STx2. Staphylococcus aureus was detected in the examined fluid cream samples, with a mean value of 7.56×104 ± 8.81×103, CFU / ml. High microbial counts of fluid cream may present a public health hazard to the consumers and so the study presented some recommendations to diminish the hazard from that product.

埃及法尤姆省销售的四种液态乳制品的细菌质量和安全

该研究旨在评估120个样本的安全性和细菌质量，包括（小型液体奶油、大型Laban rayeb、巴氏灭菌牛奶和超高温灭菌牛奶）（各30个）。这些样本是从埃及法尤姆省不同地区的零售包装中随机收集的。对样品进行细菌总数（TBC）、总大肠菌群、粪便大肠菌群，大肠杆菌和金黄色葡萄球菌分析。小规模液体奶油和巴氏灭菌乳的TBC平均值分别为1.68×106±1.3×105和4.30×103±6.66×102CFU/ml。乳液中粪大肠菌群平均值为1.87×104±8.18×103CFU/ml，仅乳液中存在大肠杆菌，平均值为2.25×103±8.63×102CFU/ml。分离的大肠杆菌经血清学鉴定分别为O125（16/30）、O158（10/30）和O1（4/30），其百分比分别为53.33%、33.33%和13.33%。通过常规PCR，大肠杆菌携带aroA和fimH基因，而不携带STx1和STx2。在检测的液体乳膏样品中检测到金黄色葡萄球菌，平均值为7.56×104±8.81×103，CFU/ml。液体乳膏的高微生物计数可能对消费者的公共健康造成危害，因此本研究提出了一些减少该产品危害的建议。

期刊介绍： Future of Food: Journal on Food, Agriculture & Society (FOFJ) was founded in 2012 in order to provide a platform for scientific debate on agriculture and food-related themes with the goal of a sustainable future for people and planet. The journal is aimed at contributing to debates on sustainable food production and consumption, and is most interested in tackling the most important challenges to the global agri-food system, such as hunger and malnutrition, depletion of natural resources, climate change, threats to biodiversity, and inequity in the agrarian sphere. The journal understands itself as a multi-disciplinary effort and is especially designed to foster interaction between different disciplines and approaches. Hence it invites inputs from social and natural sciences, arts and humanities, academics and scholar-activists, civil society and agroecology practitioners. The journal is attempting to reach its goal by providing open access to readers and allowing contributions without submission fees or publication fees. Contributors are kindly asked to keep in mind that the journal is a non-profit endeavour and that staff time is limited. The journal cannot provide guarantees or financial support for any submission and cannot accept legal responsibility for any stage of the submission process. The Editorial Board is made up by a range of international experts who devote time and energy to peer review and its members deserve gratitude and recognition for their excellent work. All communication between authors, editors, reviewers and editorial staff is conducted in an atmosphere of mutual respect. The journal will not tolerate racism, religious, ethnic and national chauvinism, misogynous and hate language and reserves the right to bar anyone who disrespects these principles from using the platform.
