Abstract

The present work endeavoured to emphasise on the huge proliferation of drug resistant microbial strains in common meat samples including pigeon duck quail domestic chicken and broiler chicken. The present work also focused on the irradiation method for controlling the pathogenic microbes in five categories of 30 meat samples collected from food markets in Dhaka Bangladesh. Half of the samples (non-irradiated) of each were prepared for microbiological profiling and the rest of the samples were gamma irradiated (6 kGy and 8 kGy). The resistant pattern of the isolates was also observed against 12 antibiotics. For non-irradiated samples the heterotrophic bacterial and fungal loads were 1.5 10� CFU/g and the faecal contamination was 10� CFU/g. Several pathogens like Salmonella spp. Shigella spp. Staphylococcus spp. Pseudomonas spp. Vibrio spp. and Listeria spp. were found up to 10�· CFU/g . These isolates were found to be resistant against single or multiple antibiotics. Meanwhile the efficacy of gamma-irradiation was outstanding on the growth of microorganisms; up to 4 log reduction was observed at 6 kGy and 6 log reduction at 8 kGy. 6 kGy and 8 kGy were found to be very effective against multi drug resistant strains.
