Utah Salmonella Livingstone outbreak investigation used patient interviews and purchase histories for rapid restaurant linkage

This outbreak investigation report describes the response to Salmonella Livingstone infections linked to a Utah restaurant. The investigation used open-ended interviews and patient purchase histories to rapidly link cases to the restaurant exposure. The report describes the identification and response process but does not report sample size, statistical measures of association, or specific clinical outcomes.

No safety or tolerability data were reported. The investigation focused on outbreak linkage rather than clinical outcomes or treatment effects.

Key limitations include the absence of reported sample size, no statistical measures of association, and no reported clinical outcomes. The observational nature of outbreak investigations means associations should be interpreted cautiously.

For clinical practice, this report illustrates how open-ended interviews and purchase histories can aid rapid outbreak investigation. However, it provides limited evidence for clinical management decisions beyond outbreak response methodology.
