Abstract

The bacteriological quality of freshwater prawn and the antibiotic resistance profile of the isolated bacteria were studied using standard microbiological procedures. The bacterial isolates were subjected to antibiotic sensitivity test by Kirby Bauer disc diffusion method to study the resistance pattern. The elemental
composition of prawn samples was analysed with atomic absorption spectrophotometer (AAS). The total heterotrophic count of the samples ranged from 1.04×105 -1.88×105 cfu/g. The coliform levels were generally high and it ranged from 3.5×104 -7.2×104cfu/g. The bacterial isolates were Staphylococcus aureus, Flavobacterium, Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, and Enterobacter aerogenes.. The bacterial isolates were highly sensitive to ciprofloxacin, ofloxacin and gentamicin but resistant to septrin, streptomycin and amoxicillin. Calcium, phosphorus and magnesium had the highest elemental composition in both whole prawn with values of 170653.26±24.50, 21145.69±15.10 and 8450.34±30.00 mg/kg respectively. The toxic metals nickel, lead and cadmium were either infinitesimal or non-detected in all samples. Freshwater prawn was found to be nutritionally rich but harbor pathogenic bacteria with multiple resistance to antibiotics which can pose serious health hazard to consumers and thus are not totally safe for human consumption especially in the raw state.
