Imported (Saba) and local (Tilapia nilotica and Nile perch) flitted fish (60 samples) were analyzed for aerobic colony count (ACC), total coliform count and for presence of Listeria monocytogenes to detect their quality. Imported flitted fish samples were lower in aerobic colony count, coliform count and also in listeria monocytogenes incidence.Aerobic colony count (ACC) was3.3±7.7x10⁶cfu/g in imported (Saba) filleted fish, 1.8±4.0x10⁷and1.8±5.0x10⁷ cfu/g in local filleted Tilapia nilotica and Nile perch, respectively. Coliforms counts were 1.3±2.8x10², 4.3±8.4x10² and 5.1±3.2x10² cfu/g in imported (Saba) filleted, local filleted Tilapia nilotica and Nile perch, respectively. The overall incidence of Listeria monocytogenes was 6.7% in imported flitted fish samples, 23.3% in local flitted fish samples (26.7% in flitted Tilapia nilotica samples and20% in Nile perch samples), which was identified by conventional PCR reaction.
