Signs of Bad Frozen Salmon
1. Physical Appearance
Fresh frozen salmon should have a firm, slightly slippery texture. If the salmon is slimy, mushy, or has an unusual color, it may have spoiled. Avoid salmon with any signs of freezer burn, such as white or brown patches.
2. Odor
Fresh salmon has a mild, slightly fishy smell. If the salmon has a strong, pungent odor, such as ammonia or sourness, it has likely gone bad.
3. Taste
If you’re unsure about the salmon’s condition, thaw a small portion and taste it. Spoiled salmon will have a sour, bitter, or metallic taste.
Potential Health Risks
Consuming spoiled salmon can lead to foodborne illnesses such as:
- Scombroid poisoning: Caused by bacteria that produce histamine, resulting in symptoms like nausea, vomiting, and headaches.
- Vibrio infection: Caused by bacteria found in raw seafood, leading to symptoms like diarrhea, cramps, and fever.
- Listeria: A serious infection that can be fatal for pregnant women, newborns, and those with weakened immune systems.
