Fish feed ingredients and fish feed from the feed industry are analysed every year to identify any undesirable substances and certain nutrients. Samples collected in 2011 and 2012 contained no heavy metals or environmental contaminants above the legal maximum limts.

Undesirable substances in fish feed

Fish feed shall be healthy and safe for the fish. Undesirable substances that stem from the different ingredients in the feed can to a varying extent be transferred from the feed to the fish. NIFES conducts the annual monitoring of fish feed. Feed ingredients and feed for farmed fish are checked for residues of legal pharmaceuticals, environmental contaminants, additives and heavy metals. In addition, a proportion of the samples is studied for illegal pharmaceuticals and feed ingredients. The farmed fish fillets are also studied for undesirable substances.
This monitoring is carried out on assignment for the Norwegian Food Safety Authority.

Strengthened feed monitoring

From 2013, the monitoring of fish feed was expanded to include more samples and become more targeted. The background for this was that while 790 spot checks were made of fish feed in 2006, fish feed monitoring was reduced to a mere 25 feed samples in 2011 and 2012. In consultation with the Norwegian Food Safety Authority, NIFES concluded that this was too few.

– Improved monitoring of fish feed. 

Includes nutrients

The monitoring of fish feed also includes certain nutrients to ensure control of how the composition of nutrient composition of fish feed may change over time.

Feed monitoring is important

Food scandals often occur because of contamination of feed to production animals. The monitoring of fish feed is important to ensure control of the whole aquaculture production chain. Together with the monitoring of the fish fillet, this is necessary to provide an overview of food safety throughout the chain.
