The safety of Norwegian farmed Atlantic salmon (Salmo salar) has been a topic of significant research due to concerns about environmental pollutants and their potential health risks to humans. This synthesis examines the levels of various contaminants in Norwegian farmed salmon and evaluates the associated health risks.
Decreasing Contaminant Levels Over Time:
Carry-Over of Contaminants from Feed to Fillet:
Comparison with Other Regions:
Risk Assessment and Tolerable Intake:
Absence of Parasitic Nematodes:
Salmonella in Fish Feed:
Research indicates that the levels of various contaminants in Norwegian farmed Atlantic salmon have generally decreased over time, and current levels are within safe consumption limits. While there is significant retention of some contaminants from feed to fillet, the overall risk to human health remains low. Additionally, the absence of parasitic nematodes and the minimal presence of Salmonella in fish feed further support the safety of Norwegian farmed salmon for human consumption.
