Abstract

The bacterial load of Clarias gariepinus (Cat Fish) sold at Opolo Market, Yenagoa, Bayelsa State was analyzed for microbial load twenty (20) hot smoked catfish was purchased from different vendors in the Opolo Marketin Yenagoa Bayelsa state and was examined for microbial loads, under standard microbiological techniques. The Total Heterotrophic Bacterial Counts (HTBC) of the analyzed catfish samples ranged from 1.3 x106 – 1.3 x107Cfu/g. The bacterial species isolated and their hierarchy of occurrence in the fish samples were as follows: Salmonella gallinurium and Salmonella pollorum (20.0%) > Escherichia coli, Proteus mirabilis and Pseudomonas aeruginosa (13.0%) > Klebsiella pneumonia, Salmonella choleraesuis and Proteus vulgaris (7.0%). The antimicrobial sensitivity profile of the bacterial isolates from the catfish samples demonstrated using gentamicin, cefixime, augmentin, nitrofurantoin, ciprofloxacin, ceptazidine, erythromycin and ceftriaxone antibiotics, revealed that the isolates were susceptible to gentamicin, cefixime and ciprofloxacin, whilst demonstrating varied degrees of resistance to augmentin, nitrofurantoin, erythromycin and ceptazidine.The Heterotrophic Bacterial Counts obtained from the study exceeded the 103Cfu/g satisfactory microbial counts for safe foods stipulated by the World Health Organization (WHO), thereby making the fishes unwholesome. Antimicrobial resistance tendencies of the bacterial isolates also increase the risks in managing diseases arising from the consumption of these fishes. therefore the need to educate the fish vendors on the importance of hygiene practices during the processing and vending stages of these fish and also highlight the importance of cooking the fish properly to consumers.
