Background: The 53rd World Health Assembly had emphasized on effective surveillance systems to bring down the burden of Food borne diseases. Functionaries of Integrated Disease Surveillance Programme (IDSP) of Solan, a mid hill district of India, on the basis of a feedback from peripheral hospital in April 2017, promptly swung into action. Objectives: (1) confirming the existence of the outbreak, (2) identifying the source and mode of transmission and (3) initiating mitigation measures. Materials and methods: A case- control study was initiated. Case definition was formulated and 70 cases admitted in two hospitals were selected. 70 Controls were recruited from Hostel Mess register by convenience sampling. A semi structured questionnaire was used to collect information. 11 food samples and water samples from two sites were sent for laboratory examination. Epidemiological survey was undertaken for assessing environmental sanitation of the area. Results: The median incubation period of illness was 6 hours. Carrot, Radish and fried rice with respective Crude Odds Ratios of 97.92, 32.76 and 33.98 were associated with illness (P = <0.0001). Bacillus cereus was identified in Carrot, Radish and Fried rice and water samples had nil Coliform count. The rice boiler was cleaned and the rotten vegetables were discarded. Thereafter no fresh case was reported. Conclusion: Existence of a robust integrated surveillance system led to the control the outbreak within one day. Trained personnel, feedback mechanisms, integrated Laboratory network were the strengths of IDSP not only confirming but also timely and efficiently managing this Food borne outbreak.
