A grand total of 100 random samples of chicken carcasses were collected from local commercial retail
shops in BeniSuef city. All samples were bacteriologically examined for determination of aerobic plate
count (APC), psychrotrophic count, Enterobacteriaceae count, Coliforms count, Staphylococcus count
and Staphylococcus aureus count. The mean values were 6.18 ± 0.67, 3.31 ± 1.33, 3.91 ± 0.96, 2.07 ±
1.87, 3.50 ± 1.68 and 2.71 ± 1.67 log cfu/g, respectively. Moreover, this study aimed to isolate and
identify Salmonella spp., Staphylococcus aureus, E. coli and Listeria monocytogens, their prevalence
percentages were 12%, 73%, 4% and 6 %, respectively, while clostridium perfringens and E.coli
O157:H7 failed to be detected in the examined samples. Salmonella could be serologically identified as
S. typhimurium, S.virchow and S.enteric with percentages of 41.70 %, 41.70 % and 16.60 %,
respectively. Moreover, the isolated serotypes of E. coli were E. coli O55 and E. coli O86 A with
percentages of 50% and 50% for each one, respectively
