Live Crab or Lobster vs Live Clams or Mussels
Both products may be sold alive, yet their refrigerated chart periods are different. Neither should be treated as ordinary picked shellfish meat.

Choose the correct food state
For both live categories the source says freezer storage is not recommended. Do not invent a freezer date from a fresh-crab-meat row.
Understand the freezer guidance
Live seafood requires particularly careful handling. If its condition or storage history is uncertain, a date calculation cannot establish safety.
Calculate from the right starting point
Open the exact food entry above to find the interactive calendar. Use the day the item was prepared, opened or refrigerated, as appropriate. Confirm timely cooling and continuous cold storage before calculating. A date does not determine whether food is safe.
Food safety: A calculation cannot verify temperatures, handling, spoilage or product recalls. Follow a shorter package use-by instruction and discard food after unsafe time at room temperature. Freezer periods concern quality only.
