Questionnaire Background for Interviewer
This questionnaire is designed to collect comprehensive information on possible risk factors for cyclosporiasis. More details are collected on high risk foods (berries, herbs and leafy greens), but please ask the case about all food items listed. Text is included above each food section to explain what information we are trying to capture and prompts to remind cases to include garnishes.
Since outbreaks of cyclosporiasis are often linked back to contaminated food products, it is critical to collect as much detail as possible on food exposures. Please collect as much detail 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 30 minutes to complete.
For local use only – please remove this page if sending to PHAC
