Live Iceberg Select™ mussels are perishable and must be cooked soon after purchase. Always check the packaging for the best before date. Mussels must be stored in the refrigerator. Do not remove mussels from the bag in which they are purchased. Place the bag in a leak-proof container until you cook them.
When you are ready to cook the mussels, rinse them under cold, running water. If some of the mussels are not tightly closed, place them in a dish of cold water and discard them if they do not close after one minute.
