Unless they have been shucked and frozen, clams should be alive when you buy and cook them. If the shell is tightly closed, it is still alive. If the shell is slightly open, it should close promptly when tapped. If the shell is open and does not close when tapped, throw it out.
Is it bad if clams are open?

Why are closed clams bad?
If the shell remains shut after cooking, he says, “the muscle that holds the shell together is working. It’s alive. Or if an oyster, clam or mussel doesn’t open when it’s cooked, sometimes it’s dead — killed in the cooking process — but the muscle is just so joined to the shell that it’s not letting go.”
Why can’t you eat closed clams?
A clam/mussel has a shell with two halves. These shells have elastic ligaments that naturally want to be open. To keep the shells closed, they have adductor muscles to hold the shells together. Most of the time the heat will denature the proteins in the adductor muscles causing it to release the shells.
Should you soak clams before cooking?
Soak your clams for 20 minutes in fresh water just before cooking. As the clams breathe they filter water. When the fresh water is filtered, the clam pushes salt water and sand out of their shells. After 20 minutes, the clams will have cleaned themselves of much of the salt and sand they have collected.
How long will clams last in the fridge?

How do you open a clam without killing it?
Put a plug into the clam to keep it open. Like the grafting process, extracting the pearl without killing the oyster requires putting in a plug to hold the shell apart. Cut the oyster and use tweezers to remove the pearl. Remove the plug and allow the oyster time to recover before grafting with the oyster again.
Can dead clams be eaten?
Do not cook or eat shellfish that have died during storage. Gaping shells indicate that the shellfish are dead and not edible. Dead shellfish spoil rapidly and develop off-flavor and off-odors.
Can clams feel pain?
