A total of Fifty (50) samples of smoked Catfish were purchased from fish traders in the market. The fish samples were analyzed using standard bacteria techniques and procedures. The result shows mean bacterial loads of 184 colonies with a population of 1.84 × 106 Cfu/g. A total of seven (7) species of bacteria were isolated from the sample. The bacteria species consist of four (4) gram-positive bacteria and three (3) gram-negative bacteria. The bacteria isolate encountered in this study were Staphylococcus aureus, Staphylococcus epidermidis, Bacillus sp., Micrococcus sp., Escherichia coli, Salmonella sp. and Proteus mirabilis. The study revealed that smoked catfish sold in Bida modern market are contaminated by different groups of bacteria, which could be due to the unhygienic nature of the market and the fish handlers.
