| dc.description.abstract | The present study was investigated to determine the bacteriological quality of frozen and unfrozen Pabda
(Ompok pabda) in the Fish Processing Plant (Eurocross Fish Processing Plant, Khadimnagar, Sylhet) during the
period of January/2015 to October/2015. For this experiment five (5) frozen samples from five different lots and
five (5) unfrozen samples which were ready for the processing and also preparation for the respective lots were
taken for the estimation of bacteriological quality of fishes. The study was considered the bacteriological
parameters such as Total Viable Count (TVC), Total Coliform (TC), and the occurrence of Escherichia coli,
Salmonella spp. and Vibrio cholera. The TVC of frozen samples were 2.9×10

CFU/g respectively. The mean bacterial load of Frozen and Unfrozen Pabda were log
5.37±0.15 and log 7.02±0.59. The frozen samples contained lower bacterial load than unfrozen samples. The
bacterial loads of frozen Pabda comply with ICMSF standard but the same of unfrozen Pabda does not comply
with this standard. The TC of frozen samples were 20, 15, 20, 21 and 27 MPN/g and furthermore, whereas the
TC of unfrozen samples were 160, 120, 120, 120 and 150 MPN/g respectively. The mean Total Coliform for
both frozen and unfrozen samples were 20.6±4.28 and 134±19.49. From this study, it is very revealed that the
Total Coliform of frozen pabda complies with ICMSF standard but the same of unfrozen Pabda does not
comply with this standard. The detected pathogenic bacteria were Esherichia coli, Salmonella spp. and Vibrio
cholera. In frozen Pabda all of the identified pathogenic bacteria were absent. All of the unfrozen samples were
contaminated with Esherichia coli, but two of the samples were contaminated with Salmonella spp. and one
sample polluted with Vibrio cholerae. The results of this study indicated that the TVC, TC and all other
identified pathogenic bacteria were higher in unfrozen Pabda than frozen Pabda. So, the bacteriological quality
of frozen Pabda complies with ICMSF standard but the same of unfrozen samples does not comply with ICMSF
standard. The results are more important for ensuring food safety as well as for export. | en_US |
