The present study was carried out to determine the abundance of pathogenic microorganisms in the frozen fish sample (Oreochromis mossambicus) collected from Ukkadam local market, Coimbatore district. The sample was kept under 4°C frozen temperature for 7 days (frozen period). The serial diluted fish muscle samples (10-5) in nutrient agar medium after 24-36 hrs were quantified for microbial pathogens using microbial counting chamber. At the end of the experiment the selected fish muscle samples during the storage period was found to be contaminated with pathogenic bacteria ranging from 3.74×105 to 16.90×105 cfu/g. The total viable count of selected sample was gradually noted to be increased during the study period. Such quantity of pathogens in the selected experimental fish sample may claim a serious public health risk.
