This study was undertaken to explore the possibility of contamination of Vibrio cholerae serogroups 01 and 0139, the most important causative organisms for life threatening acute secretory diarrhoea and also potential public health importance, by isolating these organisms from body surface, gill and intestine of common table fishes like Labeo rhoita, Catla Catla, Cirrhinus mirgala and Tilapia mosambica which were reared in sewage and raw human excrita enriched fishery ponds. Vibrio Cholerae 01 or 0139 were not isolated from body surface swabs, gills and intestine of these common table fishes. Water samples of sewage enriched fishery ponds and sewage of Calcutta municipal corporation were also processed for isolation of these organisms, however, these samples were also negative for V. Cholerae 01, 0139 and non 01-0139 serogroups. Present study indicated that there was less chance of contamination of toxigenic and disease producing strains of V. cholerae by common table fishes which were reared in sewage and raw faecal matter enriched fishery ponds.
