Abstract This study was carried-out to evaluate the mictobial examination of fresh chicken carcass through: -Determination of total aerobic bacterial counts. -Determination of total enterobacteriaceae count. -Detection of E. coli count. -Determination of total coliform count. -Detection of salmonella count. -Determination of total mould and yeast count. This study was carried-out on a total of 100 random samples of (Breast and thigh) 50 of each of freshly slaughtered broilers were collected from different groceries and supermarkets in different localities at Alexandria government.the samples were collected and kept in an icebox at 6° C and transferred with a minimum of delay to the laboratory for further examination. All samples were subjected to chemical and microbiological examination to ensure that the samples were apparently fit for human consumption. Our results concluded that: 1-The Aerobic plate counts showed that, the higher level of aerobic plate count observed in thigh muscle as it reached to (7.10 X 105) than the breast muscle (2.80 X 105), Also, the samples that showed a higher level of aerobic plate counts than the permissible limit was 38 (76 %) of the examined samples in thigh muscle and in breast muscle it reached to 23 (46 %). 2-The total Enterobacteriaceae cleared that, the higher level of total enterobacteriaceae counts observed in thigh muscle (2.0×103) than the breast muscle (1.3×103). 3-The E. coli incidences in examined samples showed that, the higher level observed in thigh muscle samples 24 (48 %) than the breast muscle samples 20 (40 %). 4-Our results on the total coliforms counts cleared that, the higher level of total coliforms count observed in thigh muscle (1.8×103) than the breast muscle (1.1×103). Also, our results also observed in Table (5) cleared that, the number of samples above the permissible limit reached to 50 (100%) in the thigh muscle and 30 (60 %) of the samples of breast muscle. 5-While, our results on Salmonellae counts indicated that, the incidences of salmonellae in examined samples cleared that, the higher level observed in thigh muscle samples 11 (22 %) than the breast muscle samples 9 (18 %). 6-The total yeast count showed that, the higher level of total enterobacteriaceae counts observed in thigh muscle (2.3×103) than the breast muscle (2.2×103). 7-The total mould count cleared that, the higher level of total mould counts observed in thigh muscle (1×103) than the breast muscle (0.73×103). |
