Abstract

The study was conducted on 100 random samples of frozen chicken meat cuts represented by chicken wings, drumstick, thigh and breast (25 of each) purchased from different markets at Qalubiya Governorate, Egypt. The collected samples were bacteriological examination to investigate the bacteriological quality. The obtained results cleared thatthe mean values of APC, psychrotrophs; coliforms and S. aureus counts (CFU/g) of the wing samples were the most contaminated with such bacterial groups followed by drumstick, thigh, and breast samples. Further, bacteriological isolation of some food poisoning bacteria revealed detection of E. coli and coagulase positive S. aureus (CoPSA) in 11, and 21% of the examined samples, respectively. On the other hand, Salmonella species could not be detected in any of the examined samples. Concerning detection and typing of some enterotoxigenic CoPSA, 5 isolates were randomly examined using SET- RPLA test and the results indicated detection of Staphylococcal enterotoxin A in 3 isolates (60%), while Staphylococcal enterotoxins C and D were detected in one isolate (20% of each). Therefore, the sources and public health significance as well as trials for control of such serious food poisoning bacteria were discussed.
