How Long Does Fish fillet Last?
Storage times and freshness tips for fish fillet 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 fridge (fresh fish)1-2 days (up to 3 days if exceptionally fresh and handled perfectly)
Signs of Spoilage
Strong, pungent 'fishy' or ammonia-like odor; dull, faded, or discolored flesh (e.g., grey, yellow, green spots); cloudy or sunken eyes (if whole fish); milky, thick liquid accumulating; slimy or sticky texture.
How to Check
Smell Test: Fresh fish should have a mild, clean, oceanic, or almost no smell. A strong 'fishy,' sour, or ammonia smell indicates spoilage. Visual Inspection: Look for bright, translucent flesh (depending on fish type). Avoid dull, discolored, or dried-out areas. Touch Test: The flesh should be firm and spring back when pressed gently. It should not feel slimy, mushy, or sticky.
Storage Tips
Store fish in the coldest part of your refrigerator, ideally on a bed of ice in a perforated container placed inside another container to catch drips. Wrap tightly in plastic wrap or place in an airtight container to prevent odors from spreading and to avoid cross-contamination. Consume as soon as possible.
cooked in freezer4-6 months
Signs of Spoilage
Freezer burn; off-flavors (e.g., rancid, stale) upon thawing and reheating; dry, tough, or mushy texture after thawing; loss of original flavor and quality.
How to Check
Visual Inspection: Check for freezer burn or excessive ice. Smell Test: After thawing, check for any off-odors. Taste Test (small portion): If unsure, taste a small, reheated piece. Any unpleasant or 'off' taste means it should be discarded.
Storage Tips
Cool cooked fish completely before freezing. Store in airtight, freezer-safe containers or vacuum-sealed bags to prevent freezer burn. Label with the date. Thaw safely in the refrigerator and reheat thoroughly to 165°F (74°C).
cooked in fridge (leftovers)3-4 days
Signs of Spoilage
Sour, rancid, or unpleasant odor; dry, hard, or rubbery texture; visible mold growth; dull or discolored appearance; slimy film on the surface.
How to Check
Smell Test: Any off-odor (sour, 'old fish,' rancid) is a clear sign. Visual Inspection: Look for any unusual discoloration, fuzzy spots (mold), or a dull, dry appearance. Touch Test: The fish should not feel slimy or excessively dry/hard.
Storage Tips
Allow cooked fish to cool completely (within 2 hours) before transferring to an airtight container. Refrigerate promptly. Reheat thoroughly to an internal temperature of 165°F (74°C).
raw in freezer3-6 months (lean fish like cod, tilapia); 2-3 months (fatty fish like salmon, tuna, due to higher risk of rancidity)
Signs of Spoilage
Severe freezer burn (dry, leathery, discolored patches); strong rancid, 'fishy,' or off-odor upon thawing; mushy, excessively dry, or fibrous texture after thawing; lack of fresh fish flavor once cooked.
How to Check
Visual Inspection (pre-thaw): Check for excessive ice crystals or freezer burn. Smell Test (post-thaw): Thaw safely in the refrigerator. A strong, unpleasant odor upon thawing indicates spoilage. Touch Test (post-thaw): The texture should be relatively firm, not overly mushy or crumbly.
Storage Tips
For best quality, wrap individual fillets tightly in plastic wrap, then an additional layer of aluminum foil, or use a vacuum sealer. This prevents freezer burn and extends shelf life. Label with the date. Thaw frozen fish slowly in the refrigerator, never at room temperature.
warning: at room temperatureMaximum 2 hours (total time out of refrigeration/freezer, including prep). If ambient temperature is above 90°F (32°C), reduce to 1 hour.
Signs of Spoilage
Rapid development of a strong 'fishy' or ammonia-like odor; visible slime or discoloration appearing quickly; presence of flies or other pests.
How to Check
Time is the primary indicator. If it has been out longer than the recommended safe time, it is unsafe regardless of appearance or smell. Smell Test: The odor will quickly turn foul. Visual Inspection: Look for rapid changes in color or appearance.
Storage Tips
Fish is a highly perishable food and enters the 'danger zone' (40-140°F / 4-60°C) very quickly at room temperature, allowing harmful bacteria to multiply rapidly. Never leave fish out for extended periods. Always refrigerate or freeze promptly.
