从埃及吉萨省的不同超市和商店共收集了75个肉制品样品，其中kofta、香肠和shawerma各25个，进行细菌学检查以确定其卫生质量。本研究于2009年4月至7月进行。平均好氧菌数分别为28.4× 105、24.3× 104和7× 105 CFU/g。大肠菌群（MPN）分别为7× 102、3× 102和4.59× 102 CFU/g。大肠杆菌、沙门氏菌、克雷伯氏菌和变形杆菌分别从7份（28%）、0份（0%）、4份（16%）和2份（8%）、3份（12%）、2份（8%）、1份（4%）和2份（8%）、5份（20%）、1份（4%）、3份（12）和2份（8%）的kofta、香肠和shawerma样品中分离出来。此外，从1份（4%）shawerma样本中分离出柠檬酸杆菌属。80%的大肠埃希菌为肠致病性（O 166、O 78、O 126、O 55、O26、O20、O25：K11、O 119、O 125：K70、O 146、O 126），20%的大肠埃希菌为不定型。从8%的香肠样品中分离出了本坦坦沙门氏菌，而从4%的沙威马样品中分离出了肯塔基州沙门氏菌。
A total of seventy five samples of meat products, 25 of each of kofta, sausage, and shawerma were collected from different supermarkets and shops in Giza governorate, Egypt to be examined bacteriologically to determine its sanitary quality. The current study was done at April to July 2009. The mean aerobic plate count values were 28.4×10 5 , 24.3×10 4 and 7×10 5 CFU/g, respectively. Enterobacteriaceae count was 10.14×10 5 , 5×10 4 and 37.8×10 4 CFU/g, respectively While the Coliforms (MPN) count was 7×10 2 , 3×10 2 and 4.59×10 2 CFU/g, respectively. Escherichia coli, Salmonella spp, Klebsiella spp and Proteus spp were isolated from 7(28%), 0(0%), 4(16%) and 2(8%); 3(12%), 2(8%), 1(4%) and 2 (8%); 5 (20%), 1(4%), 3(12) and 2(8%) of kofta, sausage and shawerma samples respectively. Further, Citrobacter spp was isolated from 1(4%) of shawerma samples. 80% of Escherichia coli isolates were enteropathogenic (O166, O78, O126, O55, O26, O20, O25 : K11, O119, O125 : K70, O146, O126) while 20% were untypable. Salmonella Buntantan was isolated from 8% of sausage samples while Salmonella Kentucky was isolated from 4% of shawerma samples.
