| Abstract | ||||
| One hundred of random frozen chicken carcasses were purchased from supermarkets in Cairo Governorate for bacteriological examination. Standard methods were used to and some aerobic determine anaerobic microorganisms. Samples were classified into two groups (50 of each). Group I was examined for anaerobes, group II was frozen at -18°C for 1, 2, 3 months then examined for aerobic bacteria. Isolates from group I were C. sporogenes, C. perfringes and C. sordelli with incidences of 15%, 12% and 12%, respectively. While the mean value of total bacterial counts were 0.21x104+1.00 after One month, 1.31x103+5.97 after two months and 0.2x104+1.4 after three months of freezing with a reduction 98.60%, while the mean value of Enterobacteriaceae counts were 1.4x102+1.1, 0.71x102+3.18 and 1.92x10+8.19 organisms/cm? after freezing for 1, 2 and 3 months, respectively with a reduction 98.3%. The incidence of Staphylococcus spp. Were 60%, 70%, 20% and 16% after one month, while it was 50%, 56%, 16% and 14% after 2 months and 44%, 48%, 14% and 12% after 3 months for neck skin samples, cloaca skin swabs, muscles of thigh and breast. Salmonella strains recovered from the examined samples were 10%, 12%, 2% and zero%. Antibiogram of antibiotic sensitivity of prevalent isolates were conducted. Application of decontaminant | ||||
