8 Types of Fish You Should Think Twice About Eating - Even When They're Cheap

Transparency remains one of the most important indicators of quality.

6. Fish High in Environmental Contaminants

Certain fish may accumulate pollutants depending on where they live.

Potential contaminants can include:

  • Mercury
  • PCBs
  • Industrial pollutants

Most regulatory agencies monitor seafood safety carefully, but contamination concerns remain an important topic of research.

Consumers often reduce potential exposure by:

  • Eating a variety of fish
  • Following local consumption advisories
  • Choosing reputable suppliers

Moderation Matters

Even nutritious foods are often best consumed as part of a varied diet.

Diversity helps minimize potential risks.

7. Fish Sold at Unusually Low Prices

If a deal appears unusually good, it may be worth asking why.

Potential explanations include:

  • Near-expiration products
  • Excess inventory
  • Lower-quality grading
  • Storage issues

This does not automatically mean the fish is unsafe.

However, consumers should inspect products carefully and ask questions when prices seem unusually low.

8. Fish That Have Been Repeatedly Frozen and Thawed

Repeated freezing and thawing can affect:

  • Texture
  • Flavor
  • Quality

Signs may include:

  • Excessive ice crystals
  • Dry flesh
  • Mushy texture after cooking

Proper freezing can preserve fish exceptionally well.

The concern arises when temperature control has been inconsistent.

Frozen Fish Can Be Excellent

Many consumers mistakenly assume fresh fish is always superior.

In reality, fish frozen shortly after harvest can often be of very high quality.

The issue is repeated thawing and refreezing.

How to Choose Better Fish

When shopping for seafood, consider these tips:

Check the Smell

Fresh fish should smell like the ocean, not ammonia or strong fish.

Examine the Eyes

Clear, bright eyes are generally a good sign.

Inspect the Flesh

Firm, elastic flesh usually indicates freshness.
