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 blue MSC label has come from a fishery certified as sustainable.
