Razor clams are prized for their firm texture and briny flavor, but as a highly perishable seafood, they require careful handling. To maintain peak freshness, these bivalves must be kept chilled and moist immediately after purchase. Because they are safety-critical, any sign of dullness or open shells indicates they are no longer suitable for consumption. Proper refrigeration is the only way to slow down the degradation process, but even then, a very short window exists before the risk of spoilage becomes significant. Always prioritize freshness by inspecting the shells and scent immediately upon bringing them home.

Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

What does a safe razor clam look like?

A safe clam has a tightly closed shell and a clean, shiny surface without any slimy film or off-putting odor. If they are open or smell unpleasant, they should not be consumed.
