A total of 125 random samples of fresh chicken, meat beef and beef meat products viz: minced meat, beef burger and sausage (25 for each), were collected from different shops in Benha city. The bacteriological examination of the samples indicated the isolation of food-borne pathogens from 79 positive samples (63.2%) where, 113 isolates of food-borne pathogens were recovered from these samples, includes E. coli (46.9%), Salmonellae (17.7%) and S. aureus (35.4%). They were isolated from minced meat samples (28.3%) followed by sausage, chicken meat, beef meat and beef burger samples with an incidence of 21.2%, 19.4%, 18.6%, and12.4%, respectively. E. coli strains (53) were isolated mostly from minced meat samples (13 = 24.5%) followed by sausage (12 = 22.6%), beef meat (11 = o 20.8%), chicken meat (10 = 18.9%) and beef burger samples (7 = of 13.2%). Different serotypes of E. coli (O55:H7, O78, O111:H4, O26:H11, O119:H4, O125:H18 beside 10 untyped strains) were recorded. All E. coli strains are sensitive to enrofloxacin, cefotaxime, gentamycin and norfloxacin. Salmonella strains (20) were isolated from minced meat (7 = 35%), sausage and chicken meat (4 = 20.0% for each one), beef meat (3 = 15%) and beef burger samples (2=10%).Three serotypes of Salmonellae were isolated as S. Typhimurium (10 = 50%), S. Enteritidis (8 = 40%) and S. Typhi (2 = 10%) were recorded. The isolated Salmonella strains were highly sensitive to gentamycin, norfloxacin, enrofloxacin, ciprofloxacin and cefotaxime. S. aureus strains (40) were isolated from minced meat (12 = 30%), sausage and chicken meat (8 = 20% for each one), beef meat (7 = 17.5%) and beef burger (5 = 12.5%). All isolated strains were coagulase positive S. aureus. 6 strains out of 10 randomly examined S. aureus strains (60.0%) were enterotoxigenic and classified according to type of toxin into (3A, 1B, 1C, 1A&C). Moreover, the isolated S. aureus was highly sensitive to norfloxacin, enrofloxacin, gentamycin and ciprofloxacin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
