How Long Can You Keep Manila Clams?
Manila clams should be kept alive until ready to use or cook. They can be kept in a container in the refrigerator for up to 2-3 days. It’s important to store them in an open container or a container with holes to allow air circulation and keep them from suffocating. It’s best to discard any clams that are open and do not close when tapped, or clams with broken or damaged shells.
