Norwegian farmed fish remains a safe choice for consumers, according to the latest annual monitoring report from the Institute of Marine Research (IMR). The 2024 study, carried out on behalf of the Norwegian Food Safety Authority, examined 888 fish and generated over 30,000 test results. None showed levels of illegal or harmful substances above European Union (EU) safety limits.
“We’re delighted to see that once again, tests show no exceedance of harmful substances or pollutants. This proves that Norway’s strict monitoring system provides global consumers with confidence in farmed Norwegian fish,” said Martin Skaug, director of communications at the Norwegian Seafood Council.
Strict checks every year
By law, all Norwegian farmed fish must undergo annual testing to ensure food safety. Samples are taken from both fish farms and slaughterhouses, covering species such as salmon, trout, cod and halibut. The IMR then analyses the samples for illegal substances, veterinary medicines, and environmental pollutants.
This year’s findings showed no residues of unauthorised drugs, such as growth hormones. Antibiotics and other veterinary medicines were also absent. Traces of treatments for sea lice were found but remained well below permitted thresholds. Tests for heavy metals, PFAS, dioxins and PCBs all came back clear.
Looking ahead: new contaminants under the microscope
For the first time, the monitoring included so-called “emerging contaminants” – chemical compounds that may become a future concern. Some were detected, but at very low levels, and researchers stress there is not yet enough data to assess health risks.
“Adding new contaminants shows how the IMR is working proactively, applying precautionary principles to stay ahead of possible risks,” Skaug said. The results will be shared with the European Food Safety Authority (EFSA) for further evaluation.
The annual monitoring, carried out under both Norwegian and EU regulations, remains a cornerstone in maintaining consumer trust in Norwegian seafood – a trust built on transparency, science, and strict oversight.
