Questionnaire Background for Interviewer

This questionnaire is designed to collect comprehensive information on possible risk factors for salmonellosis. It is designed for cluster/outbreak investigations where the source of infection is unknown, but the questionnaire could be applied to investigate sporadic cases. The exposure period for this questionnaire was extended to 7 days to reflect the observation that many Salmonella outbreaks have median incubations periods >3 days,

Data captured: – Case demographics – Food exposures

– Clinical information – Pet exposures

– Laboratory information – Other risk factors

Since outbreaks of salmonellosis are often linked back to contaminated food products, it is critical to collect as much detail as possible on food exposures. Therefore this questionnaire has both an open ended food history followed by a detailed check list of food items; this may seem repetitive but is used to ensure all possible food exposures are captured. Please collect as much details as possible for each item, including restaurant exposures. Also consider using a calendar to probe and collecting receipts, purchase data or loyalty cards if available.

The questionnaire is estimated to take 45 – 60 minutes to complete
