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) was 3.3±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 and 20% in Nile perch samples), which was identified by conventional PCR reaction.
