Pantry

Not Recommended

Unsafe

Live seafood requires refrigeration or specific conditions to remain alive and safe for consumption. Do not store at room temperature.

Refrigerator

1-2 days for live shellfish (clams, mussels, oysters); 2-4 days for live crabs/lobsters

Store live shellfish (clams, mussels, oysters) in the coldest part of the refrigerator (40°F/4°C or below) in a breathable bag (e.g., mesh bag or bowl covered with a damp, clean cloth) to allow them to breathe. Do not store in airtight containers or submerged in water. Store live crabs and lobsters in a container with ice packs, covered with a damp cloth, in the coldest part of the refrigerator.

Freezer

Not Recommended

Not recommended for live seafood

Live seafood should not be frozen alive. For best quality and safety, cook or shuck/clean seafood before freezing. Cooked shellfish or crustaceans can be frozen for 2-3 months.

Signs of Spoilage

  • For live shellfish (clams, mussels, oysters): open shells that do not close when tapped, strong fishy or off-odor, dry appearance.
  • For live crabs/lobsters: lack of movement, strong off-odor.
  • General signs: slimy texture, strong ammonia-like smell.

Room Temperature Safety

2-hour rule (1 hour if ambient temperature is above 90°F/32°C)

40°F–140°F (4°C–60°C)

Live seafood should be kept cold and moist. Do not leave live seafood at room temperature for more than 2 hours (1 hour if above 90°F/32°C) before cooking or refrigerating, as bacteria multiply rapidly in the danger zone.

Expert Tips

Safe Handling

1

Keep live seafood alive until cooking. Discard any shellfish that are open and do not close when tapped. Discard any crabs or lobsters that are not moving.

2

Wash hands thoroughly with soap and water before and after handling raw seafood.

3

Prevent cross-contamination by using separate cutting boards, plates, and utensils for raw and cooked seafood.

4

Cook seafood to an internal temperature of 145°F (63°C) as measured with a food thermometer.

5

For shellfish, cook until shells open during cooking. Discard any that do not open.
