Abstract A total of forty samples of imported frozen broiler, 20 of each trade mark were collected from main supermarkets in Cairo, Egypt and evaluated to determine the quality parameters examine each sample for deterioration criteria, then divide each into drip and skin and muscle then examine each separately microbiologically (APC, total Staphylococcus, Staphylococcus aureus, Coliform) then examined serologically for (E.coli, Salmonella). The results showed that the drip % and T.B.A and T.V.B.N. are all within the permissible limits. The results obtained showed that the APC and coliform count of drip and skin and muscle of some samples both of groups are higher than permissible limits which is may be due to bad storage and repeated thawing and freezing of samples , also isolated Staphylococcus aureus , E.coli, Klebsiella, Proteus mirabilis, Proteus vulgaris , but failed to isolate Salmonella. The results revealed that group B is better than group A. The results showed that the skin has higher APC and Staph. aureus. So for effective improvement of frozen broiler by hygienic slaughter, evisceration, washing, chilling and freezing, and by continuous stable freezing during storage at -18 ºC . |
