Quick Answer
Yes, it is safe to refreeze salmon that has been properly defrosted in the refrigerator. Refreezing salmon that was defrosted using cold water or the microwave is not recommended. When refreezing salmon, it is best to use it within 3-4 months for optimal quality.
Can You Refreeze Previously Frozen Salmon?
Salmon, like many seafood products, is highly perishable and typically frozen soon after being caught. Freezing prevents bacterial growth and preserves quality. When you purchase frozen salmon at the grocery store, it has been previously frozen.
After defrosting frozen salmon, it is absolutely safe to refreeze it provided proper defrosting procedures were followed. However, refreezing may negatively impact texture and moisture content.
Here are some key points on refreezing thawed salmon:
– Salmon that was thawed in the refrigerator can be safely refrozen. Slow defrosting minimizes moisture loss.
– Salmon thawed using the cold water method can be refrozen, but there may be some texture and moisture changes.
– Salmon defrosted in the microwave should not be refrozen, as it likely cooked from the edges and has lost too much moisture.
– Refrozen salmon will not taste as fresh, but it is still safe to eat. Use refrozen salmon within 3-4 months for best quality.
– Refreezing salmon more than once is not recommended as it continues to degrade texture and moisture.
Proper Defrosting Methods for Salmon
To safely refreeze salmon, it is important to use proper defrosting methods that minimize bacterial growth and quality changes:
Refrigerator Defrosting
– Place frozen salmon in a bowl or on a plate to catch drips
– Defrost overnight in the refrigerator (40°F or below)
– This slow thawing helps maintain quality and prevents bacterial overgrowth
Cold Water Defrosting
– Place salmon in a leak-proof bag submerged in cold tap water, changing water every 30 minutes
– Defrost time depends on thickness, but typically takes 1-2 hours
– Cook fish immediately after thawing
Microwave Defrosting
– Place frozen salmon in a microwave-safe container
– Defrost at 30% power, flipping halfway through
– Cook fish immediately, as edges may become warm and start to cook
The refrigerator method is ideal, as the fish thaws slowly and evenly. Cold water thawing is faster but can affect texture. Microwaves can begin cooking the outer portions, so refreezing is not recommended.
Steps for Properly Refreezing Salmon
Follow these steps for safe refreezing of thawed salmon:
1. Inspect the Salmon
– Check for any signs of spoilage like sliminess, dull flesh, or a fishy odor. Discard if salmon seems spoiled.
2. Prepare the Salmon
– Pat dry with paper towels and remove any frost crystals or ice glaze.
– Portion the desired amount for refreezing. Freeze remainder.
– Place in moisture-proof packaging or wrap tightly in plastic wrap or foil.
3. Freeze Promptly
– Freeze salmon within 1-2 days of purchasing or thawing.
– Freeze at 0°F or below. Use the coldest part of the freezer.
4. Label Package
– Label package with name and new freeze date.
– Use refrozen salmon within 3-4 months for best quality.
5. Use Proper Thawing
– Thaw refrozen salmon properly in the refrigerator, cold water, or microwave before cooking.
Following this process will allow you to safely refreeze salmon while minimizing impacts on texture and flavor.
How Long Does Refrozen Salmon Last?
Refrozen salmon that has been stored and thawed properly will retain its safety and nutrition indefinitely but may suffer some quality loss with extended freezing.
Here are some guidelines for salmon that has been refrozen:
– Texture – Flesh may become slightly mushier with each refreeze
– Moisture – More moisture loss may dry out refrozen salmon
– Flavor – Refrozen salmon is safe but may lose freshness and flavor
– Appearance – Repeated thawing and freezing can turn the pink flesh brownish
– Nutrition – Minimal nutrient loss during refreezing
For best quality, refrozen salmon should be consumed within 3-4 months. Properly wrap salmon with minimal air exposure and freeze below 0°F.
Tips for Refreezing Salmon
Here are some tips for preserving optimal quality when refreezing salmon:
– Double wrap salmon in freezer bags or foil to prevent freezer burn
– Minimize thawing and refreezing cycles to preserve texture
– Glaze with ice to protect from air exposure if freezing for over 1 month
– Portion salmon into usable amounts before refreezing
– Label packages with contents and dates to track freshness
– Use within 3-4 months for best flavor, texture, and appearance
– Cook refrozen salmon thoroughly to at least 145°F internal temperature
How to Tell if Refrozen Salmon is Bad
It can be difficult to determine safety just by looking. Here are some signs that refrozen salmon has spoiled and should be discarded:
– Unpleasant ammonia-like odor
– Slimy, mushy consistency
– Discoloration and graying of flesh
– Presence of mold, usually whitish or black spots
– Dry, flaky flesh indicating freezer burn
– Significantly dried out appearance from moisture loss
Do not taste salmon with any signs of spoilage. When in doubt, remember the old saying “When fish smells bad, it is bad!” Discard fish with odors, textures, or colors that seem off.
Is it Safe to Eat Refrozen Salmon Raw?
It is not recommended to eat refrozen salmon raw or undercooked. The freezing process destroys some parasites, but refreezing may allow any remaining parasites to continue growing.
Additionally, the quality changes from refreezing make raw preparations like sushi and sashimi unappealing.
For safety, raw refrozen salmon should be cooked to 145°F. Smoking to 150°F also destroys parasites. Freezing sufficiently kills parasites in fish intended for raw consumption like sushi and lox.
Can You Cook Salmon from Frozen?
Yes, you can cook frozen salmon directly without thawing first. Cooking from frozen takes about 50% longer than thawed. Adjust oven temperatures and cook times accordingly.
Here are cooking guidelines when using frozen salmon:
| Cooking Method | Instructions for Frozen Salmon |
|---|---|
| Oven Baked | Bake at 400°F for 20-25 minutes until opaque and flakes |
| Pan Fried | Fry over medium high heat for 7-10 minutes per side |
| Grilled | Grill on high heat for 10 minutes per side, flipping carefully |
| Poached | Cook in simmering 170°F liquid for 10-15 minutes |
| Microwave | Microwave on 50% power for 6-8 minutes, flipping halfway |
Cooking from frozen requires some adjustments but can be more convenient than waiting for salmon to thaw. Just be sure to cook thoroughly to an internal temperature of 145°F.
Can Thawed Salmon Sit at Room Temperature?
Thawed salmon should not sit at room temperature for more than 2 hours before cooking or refreezing. The USDA recommends storing thawed fish for no more than 1-2 days in the refrigerator.
Bacteria grow rapidly on perishable seafood like salmon when left out too long. Salmon should be promptly cooked, eaten, or returned to the fridge or freezer within 2 hours of thawing. Discard any salmon left out longer.
When thawing salmon, plan ahead to cook immediately or refreeze. Do not attempt to thaw on the counter or in standing water which allows exterior bacteria growth.
Conclusion
Refreezing salmon is a safe practice if it has been defrosted and handled properly. For best quality, use refrozen salmon within 3-4 months and be sure to cook thoroughly to 145°F internal temperature. Follow safe refrigerator or cold water thawing methods before refreezing. While refrozen salmon may lose some freshness, flavor, moisture and texture, it still retains its nutritional value and can be safely consumed if thawed and cooked properly. With care in storage, thawing, and refreezing, salmon can be safely frozen and refrozen multiple times.
