Our Chain of Custody Standard makes sure that seafood with the MSC blue fish label comes from fisheries that are MSC certified.
Ocean to Plate
All along the supply chain, from the ocean to your plate, MSC certified seafood is separated from non-certified seafood. This is thanks to the MSC Chain of Custody (CoC) Standard.
Every company at every step along the supply chain must be audited so you can trust that you're getting sustainable seafood. We regularly check to confirm that MSC certified businesses in the supply chain can prove that the seafood they purchase is from an MSC certified supplier, and they must have a record of where it has been sold to.
More than 45,000 sites around the world, including supermarket chains, fishmongers, hotels, and restaurant chains are part of this global network of certified supplies.
