Within Veterinary Public Health there are two different systems widely used for Risk Assessment.

  1. The OIE International Animal Health Code system (Covello-Merkhofer model).
    Although used by the OIE in the context of trade issues, it is flexible and can be appied to various situations.
    This consists of the following steps.
    1. Release Assessment.
    2. Exposure Assessment.
    3. Consequence Assessment.
    4. Risk Estimation.

  2. The Codex Alimentarius Commission System (NAS-NRC model).
    This is used principly for microbiological food safety risk assessments.<It consists of the following steps.
    1. Hazard identification.
    2. Hazard characterisation.
    3. Exposure Assessment.
    4. Risk Characterisation.
