Prevalence and antibiotics susceptibility patterns of some bacterial isolates from a street vended fruit product

Abstract

The study is aimed to evaluate the food safety status of a street vended fruit product locally known as fruit chat. Sample collection was carried out from four groups of vendors which were discriminated based on their mobility, vending practice and storage facility. The extent of prevalence for Enterobacter species, Escherichia coli, Klebsiella species, Salmonella species, Staphylococcus aureus and S. epidermidis was assessed in fruit chat samples. Bacterial isolates were identified through biochemical characterization. The degree of susceptibility of these isolates was evaluated against six different antibiotics that is, amikacin, ampicillin, ciprofloxacin, gentamycin, ceftriaxone and co-trimoxazol using disc diffusion method. Results indicated a higher (10 5 to 10 10 CFU/g) total plate count (TPC) and total coliforms count (TCC) ranged from 10 4 to 10 9 CFU/g in samples collected from mobile vendors without covering. Mobility of vendors and, use of no covering, resulted in significant (P
