Bhattacharya National Institute of Cholera and Enteric Diseases Thandavarayan Ramamurthy National Institute of Cholera and Enteric Diseases Salmonella enterica serovar Weltevreden and Vibrio fluvialis were identified as etiological agents of a foodborne gastroenteritis outbreak after an Iftar feast in North Dumdum. Of the 278 cases admitted to the Infectious Diseases Hospital, Kolkata, 44 stool samples were tested for the enteric pathogens. Six were positive for Salmonella Weltevreden, 5 for Vibrio fluvialis, and 8 contained both of the pathogens. Consumption of mutton-ghogni might have been the likely vehicle of this outbreak. In the pulsed-field gel electrophoresis, Salmonella Weltevreden was identified as a single clone but the V. fluvialis strains were heterogeneous. No potential conflict of interest relevant to this article was reported.
