ABSTRACT
Present study attempted to determine the prevalence of pathogenic microflora along the two major sea fish samples: Rupchanda (Pampus chinensis) and Surmai (Scomberomorus guttatus), collected from local market in Dhaka city. Most of the fishes collected were found to be contaminated with a huge number of pathogens within a range of 2.0×102-1.9×109 cfu.mL-1 or cfu.G-1. The study of antibiogram showed a number of isolates to be drug-resistant. The investigation also endeavored to evaluate the efficiency of gamma (γ) irradiation on the pathogenic reduction besides the traditional means. The pathogenic load was found to be reduced by an irradiation dosage of 3 kilo Gray (kGy).
