In the current study, a total 90 samples were collected random way from three different fish species (Ttilapia niloticus, Mugil cephalus and Clarias) 30 of each type collected from Kafr El-Sheikh city, Egypt. These samples were subjected for bacteriological examination to evaluate the quality and freshness in farmed fish. The mean value of total bacterial count / g of Tilapia niloticus, Mugil cephalus and Clarias gariepinus were 6.73×104 ± 2.03 ×104, 8.33×103±2.32× 103 and 4.1×103 ± 7.69×102 cfu/g, respectively. The mean values of coliformscount / g were 3.25×102 ± 8.04×10, 2.1×102 ± 6.74×10 and 1.06×102 ± 5.0×10 MPN/g, respectively. The mean values of staphylococcal count /g were 2.44×105 ±7.13×104, 8.67×103 ±2.23×103 and 4.74×104 ± 7.48×103 cfu/g respectively. The incidence of S. aureus was 33.3%, 30% and 46% respectively, E. coli was 36.6%,26.6% and 43.33%,salmonella was 33.3%,16.6% and 36.3%, Aeromonas hydrophila was 80%,76.6% and 90% and Pseudomonas aeruginosa was 43.3%, 80% and 76.6%.
