How Long Does White fish fillets Last?

Storage times and freshness tips for white fish fillets in different conditions.

Safety first: This guide provides general information. When in doubt, throw it out! Trust your senses and err on the side of caution. If something smells, looks, or tastes off, don't consume it.

Raw in Freezer
3-6 months

Signs of Spoilage

Severe freezer burn (dry, leathery, discolored patches, especially whitish or brownish on the surface); strong 'fishy' or off-odor upon thawing; excessively dry or mushy texture after thawing; large ice crystals indicating moisture loss.

How to Check

  1. Visual Inspection (Frozen): Look for signs of freezer burn. While safe to eat, it significantly degrades quality.

  2. Smell Test (After Thawing): Thaw the fish properly in the refrigerator, then check for any strong, unpleasant odors.

  3. Texture Check (After Thawing): After thawing, the fish should still feel relatively firm. If it's very mushy or excessively dry, quality has likely degraded significantly.

Storage Tips

To prevent freezer burn and preserve quality, wrap individual fillets tightly in plastic wrap, then an additional layer of aluminum foil or place in a freezer-safe bag, removing as much air as possible (vacuum sealing is ideal). Label with the date. Thaw slowly in the refrigerator, never at room temperature. Once thawed, use within 24 hours and do not refreeze.

Cooked in Freezer
4-6 months

Signs of Spoilage

Severe freezer burn (dry, leathery, discolored patches); off-flavors or stale taste after thawing and reheating.

How to Check

  1. Visual Inspection (Frozen): Check for freezer burn.

  2. Taste Test (After Reheating): If the taste is significantly off, stale, or unpleasant after proper thawing and reheating, it should be discarded.

Storage Tips

Cool cooked fish completely before freezing. Store in airtight, freezer-safe containers or heavy-duty freezer bags, removing as much air as possible. Label with the date. Thaw in the refrigerator and reheat thoroughly to 165°F (74°C).

Cooked in Refrigerator
3-4 days

Signs of Spoilage

Unpleasant, sour, or strong 'fishy' odor; dry, hard, or rubbery texture that was previously moist; visible mold growth (though less common for fish); significant darkening or discoloration; a noticeably 'off' taste if consumed (do not taste if other signs are present).

How to Check

  1. Smell Test: Check for any sour or strong, unpleasant odors that weren't present when fresh.

  2. Visual Inspection: Look for any mold, unusual discoloration, or a dried-out appearance.

  3. Texture Check: Cooked fish should still be somewhat flaky and moist. If it's overly dry, hard, or slimy, it's best to discard.

Storage Tips

Allow cooked fish to cool completely before refrigerating, then transfer to an airtight container to prevent odor transfer and maintain moisture. Reheat thoroughly to an internal temperature of 165°F (74°C) only once.

Raw in Refrigerator
1-2 days

Signs of Spoilage

Strong, sour, or 'fishy' odor (not a mild ocean smell); dull, faded, or grayish color; slimy or sticky texture; loss of firmness, becoming soft or mushy; visible discoloration (yellowish or brownish patches).

How to Check

  1. Smell Test: A fresh fillet should have a mild, clean, sea-like scent, not strong or ammonia-like. If it smells distinctly 'fishy' or sour, it's likely spoiled.

  2. Visual Inspection: Look for a glistening, translucent appearance. Dullness, cloudiness, or any off-colors indicate spoilage.

  3. Touch Test: Gently press the flesh with your finger. It should be firm and spring back immediately. If it feels soft, leaves an indentation, or is slimy, discard it.

Storage Tips

Store fish in the coldest part of your refrigerator, typically the bottom shelf, to prevent cross-contamination from drips. Place fillets in a sealed container or on a plate covered with plastic wrap, ideally nestled in ice, to maintain optimal cold temperatures and freshness. Do not wash raw fish before storing; pat dry with paper towels.
