Various routes of infection such as personnel, seawater and the external environment have previously been studied, but there are still many areas for improvement and a need for more knowledge about effective measures to achieve increased control of L. monocytogenes in Norwegian salmon production. Although the incidence in the raw material is relatively low, and there have been few cases of proven listeriosis linked to the consumption of Norwegian salmon products, some products may pose a potential risk, especially for vulnerable groups of the population. The companies spend considerable resources on analysis, mapping and measures in the slaughterhouses. At the same time, the industry is experiencing increased customer demands for documentation and control of L. monocyotgenes in its own production. Infection that follows the fish from the food fish farm via well boats into the slaughterhouse has been investigated previously, and it is known that persistent ""house strains"" in slaughterhouses can be a source of contamination with L. monocytogenes during processing.
Main objective:
To increase knowledge about feed and farming and its importance for contamination by L. monocytogenes in the salmon value chain. This is achieved by documenting routes of infection and risk points for L. monocytogenes from feed producers into the food fish farms and on to finished packaged fish, ready for consumption.
Sub-goals:
• To survey whether feed can be a source of L. monocytogenes in salmon and document where in the salmon feed value chain this contamination can occur.
• To map the occurrence of L. monocytogenesin the marine phase in selected food fish facilities and gain knowledge about infection can be transferred from dead fish/dead fish hoofs to other fish in the cage.
• To document infection routes for the spread of L. monocytogenes from feed and food fish farms to ready-packaged fish through whole-genome sequencing and comparative genome analysis.
• To specify effective measures to prevent the possible introduction of L. monocytogenes into the feeding system and to prevent the spread of L. monocytogenes from food fish farms to processing plants.
