Cadmium in feed to farmed salmonid fish
Rapportnr: 2005: 21
High levels of cadmium have been found in feedingstuffs for ruminants, pigs and farmed fish. The levels found in compound feedingstuff range from 11-17 mg/kg. The Norwegian Food Safety Authority has strong indications that the source of cadmium is contaminated zinc sulphate used in premixtures for feed and then further distributed to feed producers.
The Norwegian Food Safety Authority requested the Norwegian Scientific Committee for Food Safety to give an opinion on the consequences for fish health and food safety when farmed fish has been fed with feeds containing 11-17 mg of cadmium per kg of feed for a limited time period.
The Panel on animal feed concludes that feeding Atlantic salmon or rainbow trout with feeds containing 11-17 mg of cadmium per kg of feed for a limited time period (up to four months) is unlikely to cause significant fillet contamination.
