- Define what the question is
- Full anamnesis (utilize Questionnaires)
- Conduct special studies
- Post mortem studies (Specific treatment or vaccination)

(Facilitating factors/causes and/or solutions to get rid of problem)
- Systemic approach
Data:
* Mortality rate: (3+1)

What are HACCP principles?
HACCP = Hazard Analysis Critical Control Points
- Risk analysis
- Identifying critical control points
- Critical limits
- Monitoring
- Corrective actions
- Registration – written registers
- Controlling the system
Implementing HACCP principles helps to
organize effective disease preventing system
