A: Repeatedly, recipes advise us to toss out clams and mussels that do not pop open. This is an indication that the clam or mussel was not alive when cooked and, as a result, not safe to eat. However, if all the clams/mussels were fresh and closed tightly prior to cooking, they may just need a few more minutes to cook. If the clams/mussels still do not open after further cooking, or you are in doubt about the quality, throw them out.For more information about clams and mussels – selection and storage – please visit Seafood 101.
