Abstract
To address public health implication of consumption of smoked fish, a study was conducted to determine the physical and microbiological quality of smoked Oreochromis niloticus sold in Jega Central market, Kebbi State Nigeria, between June and September 2016. A total of 108 samples of the smoked fish from three retail outlets in the market - Location A (main entrance), B (center of the market) and C (motor park)) within the metropolis were analyzed for their physical and microbiological qualities using the standard cultural method on general and selective media. Results revealed that Escherichia coli, Staphylococcus aureus and Klebsiella pneumonia were present in the samples collected from the three different locations. The mean counts of the bacteria isolates found in the smoked fish samples in the three locations were A 1.5 x 106cfu/g, B 1.95 x 106cfu/g and C 2.45 x 106cfu/g. There was no significant difference (P>0.05) between locations on moisture contents of the collected samples but there was significant difference (P<0.05) among the locations in pH for the fish samples. Out of the 108 samples analyzed, 27 (25%) were positive for S. aureus while other species isolated were Klebsiella pneumonia12 (11%). The remaining 69 (64%) of the samples were negative for E. coli. The study shows that E. coli and other bacteria species are common contaminant of smoked fish in Jega Central market, and this may pose serious public health implications in the community.
Key Words: Fish processing, Fish quality, Smoked fish and Bacteria isolates
