Monitoring program for pharmaceuticals, illegal substances, and contaminants in farmed fish - Annual report for 2021

Abstract

This report summarises the monitoring data collected in 2021 on the status of illegal substances, pharmaceuticals and contaminants in Norwegian farmed fish. In 2021, a total of 14135 fish were sampled. Samples examined for illegal compounds were 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 substances. Residues of the dye crystal violet were detected in two samples of salmon. A follow-up investigation conducted by the Norwegian Food Safety Authority (NSFA) concluded with the cause likely being a contamination of the samples during sample taking. No other residues of illegal compounds were found. 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 the anti-sealice agents cypermethrin, emamectin and lufenuron were found, with concentrations below the respective Maximum Residue Limits (MRLs). Other veterinary drugs, like antibiotics or drugs used against internal parasites were not found. No environmental contaminants were found above the EU maximum level (ML).
