Abstract
One hundred and twenty fish samples, 60 each of Tilapia nilotica and Clarias lazera collected from rural areas in Giza Govomorate were subjected to sensory and baceriological examinations. The effect of different methods of heat treatment (boiling, roastin and frying) on the viability of Escherichia coil and Staphylococcus aureus was also studied. The sensory examination of the examined samples revealed that most samples can be considered fresh. Skin samples gave higher counts than muscle samples, and Clarias lazera , in gerneral gave higher bacterial counts than those of Tilapia nilotica. Staph .aureus, Escherichia coil and Yersinia enterocolitica were isolated froms examined samples. Neither Salmonella nor Vibrio parahaemolyticus could be detected. After boiling, roasting and frying of Tilapia nilotica and Clarias lazera neither Escherichia cot nor Satph. aureus could be reisolated from skin or muscle of any of the artificially infected samples.
