A total of forty samples of imported frozen broiler, 20 of each trade mark were collected from main supermarkets in Cairo, Egypt . The deterioration criteria of muscle of each sample were estimated. The drip, skin and muscle of each sample were examined microbiologically (APC, total Staphylococcus, Staphylococcus aureus, Coliform) . E.coli and Salmonella were examined serologically. 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. 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 {u00BA}C
