Bacteriological quality and antibiogram study of bacteria from "suya" and smoked fish (Clarias gariepinus) in Dutsin-Ma, Katsina State, Nigeria

Abstract

INTRODUCTION: Suya and smoked fish are cherished food delicacy in Nigeria, but can be a source of dissemination of Multi-Drug Resistant (MDR) bacteria. Moreover, there are limited studies on these MDR bacteria from Dutsin-Ma. Therefore, this study examined the bacteriological quality and antibiogram profiles of bacteria in these foods from this area in Nigeria. METHODS: Twenty samples of each of suya and smoked fish were collected from the study area and microbiologically analyzed. Total viable count, coliform count, characterization and identification of bacteria was carried out by standard microbiological techniques. RESULTS: Findings revealed that Suya samples possessed the highest total viable bacteria count (3.4x105 to 7.7x105 cfu/g) and coliform count (2.1x105 to 6.2x105 cfu/g). A total of 85 and 78 bacteria were isolated from suya and smoked fish samples respectively. E. coli (24.7% and 24.4%) was the most frequently isolated from each sample respectively. Highest (66.7%) resistance to each of cefuroxime, gentamicin, amoxillin-clavulanate and ciprofloxacin were observed among E.coli from Suya. MDR phenotypes commonly isolated was resistance to ceftazidime, cefuroxime, ampicillin, ciprofloxacin, augmentin and nitrofurantoin. CONCLUSION: This studies showed the presence of MDR bacteria in samples, hence, raise the need for improved production hygiene and public health awareness.
