The current regulatory regime places few specified safety requirements on the primary production end of seafood supply chain in most jurisdictions. Hence there is little pressure on the resources of enforcement agencies. Only NSW and Victoria currently apply hygiene and safety regulation on the seafood industry from the production end of the chain; and only one seafood sector is regulated (through licensing arrangements and not under health legislation) by all jurisdictions: the sector producing oysters and other bivalve molluscs.
The public health system e.g. hospitals, provision of pharmaceuticals, etc contributes to the care of people with food-borne illness and hence any food-borne illness associated with seafood imposes cost on government.
