(SeafoodSource) Buying sustainable seafood during their weekly shopping trips is quickly becoming a way of life for Dutch consumers. Nearly 100 percent of wild, private-label seafood sold at Albert Heijn, the Netherlands’ largest supermarket chain, and Lidl, the discount supermarket chain based in Neckarsulm, Germany, with around 10,000 stores throughout Europe, is Marine Stewardship Council (MSC)-certified.
