- Food chain investigation: Tracing contaminated products
- Environmental investigation: Identifying contamination sources
- Control measures: Product recalls, hygiene advice, public alerts
Public health response:
- Rapid case finding and notification
- Coordination across multiple agencies (FSA, FSS, local authorities)
