Abstract br Thirty five random samples of whole chicken were collected from different poultry processing plants at El-Behera Governorate. The samples were directly transferred to the laboratory with a minimum of delay where they were stored at chilling conditions (3 ± 1 °C) and examined microbiologically at 0, 2 and 4 days of storage. The results revealed that: 1. Total aerobic bacterial count. * The mean values of total aerobic bacterial counts of chicken skin and muscles (log10) at 0,2 and 4 days of storage at 3 ± 1 °C were (5.14 ± 0.07,7.63 ± 0.O8and 9.11 ± 0.13)and (2.15 ± 0.12,6.36 ± 0.14 and 7.98 ± 0.09) CFU/cm2 or g respectively. * There is a significant difference between the mean values of total aerobic bacterial counts in chicken skin and chicken muscles. * The total aerobic bacterial counts in both skin and muscles increased significantly with increasing the time of storage at 3 ± 1 °C. 2. Total psychrotrophic count: * The mean value of total psychrotrophic count of chicken skin and muscle (log10) at 0, 2 and 4 days of storage at 3 ± 1 °C were (4.26 ± 0.09, 7.27 ± 0.13 and 8.49 ± 0.13) and (1.61 ± 0.09, 6.11 ± 0.12 and 7.30 ± 0.11) CFU/cm2 org, respectively. * There is a significant difference between the mean values of total psychrotrophic counts in chicken skin and chicken muscles. |
