Know the red flags: how to determine if flounder is still fit for consumption

Flounder, a flatfish known for its delicate flavor and versatility in cooking, is a popular seafood choice among many. However, it’s crucial to know how to identify signs of spoilage to ensure you consume safe and fresh fish. This comprehensive guide will provide you with all the necessary information to determine if flounder has gone bad.

Signs of Bad Flounder

1. Appearance:

• Discolored Gills: Fresh flounder has bright red or pink gills. Brown, gray, or green gills indicate spoilage.
• Cloudy Eyes: Clear, shiny eyes are a sign of freshness. Cloudy or sunken eyes suggest the fish is old.
• Slimey Skin: A thin, clear layer of slime is normal on fresh flounder. However, excessive slime or a milky, opaque substance indicates spoilage.
• Torn or Damaged Flesh: Avoid flounder with any cuts, tears, or bruises on its skin.

2. Odor:

• Fishy Smell: A mild, briny odor is normal for fresh flounder. An intense, pungent, or ammonia-like smell indicates spoilage.
• Sour Smell: A sour or acidic odor is a clear indication that the fish has gone bad.

3. Texture:

• Firm Flesh: Fresh flounder’s flesh should be firm and springy when pressed. Soft or mushy flesh indicates spoilage.
• Dry Flesh: Overcooked or old flounder may have dry, flaky flesh.

4. Taste:

• Bitter Taste: Fresh flounder should have a mild, slightly sweet flavor. A bitter taste is a sign of spoilage.
• Metallic Taste: A metallic taste in flounder can indicate contamination or spoilage.
