How to safely freeze seafood?

Freezing seafood is a great way to preserve its freshness and quality for later use. Here’s a step-by-step guide on how to safely freeze seafood:

  1. Choose fresh, high-quality seafood: Start with fresh seafood that has been appropriately handled and stored. Look for bright, clear eyes, firm flesh, and a mild odor.
  2. Clean and prepare the seafood: Rinse the seafood under cold running water to remove dirt or debris. Pat it dry with paper towels. For whole fish, remove the scales and guts. For shellfish, remove any shells or debris.
  3. Cut the seafood into portions: If you are freezing it in large pieces, cut it into smaller, more manageable portions. This will make it easier to thaw and cook later.
  4. Choose a freezing method: There are two main methods for freezing seafood:
  • Vacuum sealing: This is the best method for freezing seafood, as it removes all air from the package, preventing freezer burn and preserving the quality of the seafood.
  • Freezer-safe packaging: If you don’t have a vacuum sealer, you can use freezer-safe packaging, such as heavy-duty freezer bags or wrapping paper. Double-wrap the seafood to prevent freezer burn.
  1. Remove air from the packaging: If you use freezer-safe packaging, squeeze out as much air as possible before sealing the package. You can also use the water displacement method, submerging the packaged seafood in a bowl of water. Any air will escape to the surface, and you can seal the package without any air bubbles.
  2. Label and freeze the seafood: Label the package with the date and type of seafood. Freeze the seafood immediately.
  3. Storage times: Seafood can be stored in the freezer for the following times:
  • Fatty fish (salmon, tuna, mackerel): 2-3 months
  • Lean fish (cod, halibut, tilapia): 6-8 months
  • Shellfish (shrimp, lobster, clams): 3-4 months
  • Cooked seafood: 2-3 months
  1. Thawing seafood: To thaw seafood, move it from the freezer to the refrigerator overnight. Alternatively, you can thaw seafood under cold running water or in a microwave.
  2. Cooking seafood: Cook seafood to an internal temperature of 145°F (63°C) to ensure it is safe to eat.

Following these tips, you can safely freeze seafood and enjoy it later.


In conclusion, while “can you refreeze fish?” has a straightforward answer, the devil is in the details. Responsible handling, storage, and consideration of quality and safety factors are crucial in making the most of frozen seafood. By being informed and mindful, you can enjoy the convenience of refreezing without compromising on taste and safety.
