Monitoring Program for Pharmaceuticals, illegal substances and contaminants in farmed fish - Annual report for 2019

Abstract

This report summarises the monitoring data collected in 2019 on the status of illegal substances, pharmaceuticals and contaminants in Norwegian farmed fish. A total of 13 725 fish were collected. Samples examined for illegal compounds would be collected at all stages of farming and are representative of farmed fish under production. The samples were analysed for substances with anabolic effects or unauthorized veterinary drugs. No residues of illegal compounds were detected. Samples tested for approved veterinary drugs and contaminants were collected at processing plants and are representative of Norwegian farmed fish ready for human consumption. Residues of anti-sea-lice agents were found in five samples, the levels present were below the Maximum Residue Limit (MRL) for all samples. Other veterinary drugs, like antibiotics or drugs used against internal parasites were not found. No environmental contaminants were found above the EU maximum levels.
