Levels of escherichia in seafood in domestic trade and their antibiotic resistance pattern
(Society of Fisheries Technologis(India), 2005) Surendra Raj, A.; Nirmala Thampuran; Surendran, P.K.
Bacteriological quality of fish/shellfish sold in retail outlets in and around Cochin, India was studied. The TPC for the different samples varied from 5.5 to 8.5 log cfu/g. The total Enterobacteriaceae count varied from 2.5 to 6.5 log cfu/g. The lactose fermenters count and total coliforms count varied from 2 to 6 log cfu/g. Seafood samples had Escherichia coli count ranging from 2 to 5.5 log cfu/g. The faecal streptococci count was between 2 to 5 log cfu/ g. The majority of the E.coli isolates showed a Multiple Antibiotic Resistance (MAR) index of more than 0.5, suggesting that they may be from high risk sources. Only a low percentage of samples were acceptable for human consumption as per Indian Standards for market sold fresh fishes. Higher count of microbial indicator organisms confirms possible presence of bacteria of public health significance and demands stringent improvement in handling and sanitary practices in the markets.
