Why certify supply chains?
Seafood products can pass through long and complex supply chains between the ocean and reaching consumers. At each stage, there is a risk that products will be mislabelled or that products from an MSC certified fishery will be mixed up with non-certified products.
Certification to the Chain of Custody Standard ensures an unbroken chain where certified seafood is easily identifiable, separated from non-certified products, and can be traced back to another certified business.
This system allows businesses and consumers to be confident that seafood with the MSC blue fish label has come from a fishery certified as sustainable.
