Scallops occur all over the world and are often traded live or freshly. Manufacturers often clean the scallops first and then pack them fresh in plastic pots or cans. These scallops have a MSC logo. This means that these scallops are caught on a sustainable basis and that the stocks are well managed. Large quantities of cleaned scallops come from American and Canadian waters. In proportion, the cleaned meat costs less than when you clean fresh scallops yourself.
