3. Risk rankings

A number of food safety hazards are associated with seafood, and the risk to public health and safety posed by each differs according to the characteristics of the particular hazard and of the seafood commodity being considered, and the amount and manner in which it is eaten. A description of these food safety hazards, the evidence for their association with seafood, and evidence linking them with adverse health effects due to consumption of seafood is presented at Appendix 4. A discussion of the interaction of the hazards with the production and processing supply chains for seafood commodities, indicating where the hazards might be introduced or where their level in seafood might be affected, is at Appendix 1.

Information provided in the appendixes is brought together in this section to provide an estimate of the likelihood of an adverse health effect due to each hazard associated with each seafood commodity or group of commodities.
These likelihood estimates are combined with the severity ranking for each hazard (from Table 3) to provide an estimate of the relative public health risk due to each hazard associated with that commodity. An overall relative risk ranking (high, medium or low) is then determined for each seafood commodity or sector, based on the highest risk ranking level pertaining to that commodity.
