Please complete questionnaire for all invasive listeriosis cases that meet the following case definition:
Clinical Evidence: Invasive clinical illness is characterized by meningitis or bacteremia. Infection during pregnancy may result in fetal loss through miscarriage, stillbirth, neonatal meningitis or bacteremia.
Laboratory Criteria for Diagnosis: Laboratory confirmation of infection with symptoms:
· isolation of Listeria monocytogenes from a normally sterile site (e.g., blood, cerebral spinal fluid, joint, pleural or pericardial fluid),OR
· in the setting of miscarriage or stillbirth, isolation of L. monocytogenes from placental or fetal tissue (including amniotic fluid and meconium)
For cases of Listeria in pregnant women or infants ≤1 month of age the MOTHER is the case.

For each food item, please give me your best guess as to whether you ATE the food, you’re not sure but you PROBABLY ate the food, or you DID NOT EAT the food. Please include foods eaten by themselves, as part of a sandwich, or as part of another food dish, including salads.
