Here’s a list of 8 types of fish that are generally recommended to avoid, either due to high mercury levels, environmental concerns, or contamination risks:
1. King Mackerel
- Very high in mercury.
- Can cause neurological problems if consumed frequently.
2. Shark
- Top predator fish → accumulates mercury and other toxins.
- Often overfished, raising environmental concerns.
3. Swordfish
- Another large predator fish with high mercury levels.
- Avoid especially for pregnant women and children.
4. Tilefish (Gulf of Mexico)
- Extremely high mercury content.
- Can pose serious health risks if eaten often.
5. Bigeye Tuna
- Contains high mercury.
- Often sold as sushi-grade tuna; limit consumption.
6. Chilean Sea Bass / Patagonian Toothfish
- High in mercury, plus many fisheries are unsustainable, harming ecosystems.
7. Orange Roughy
- Long-lived species → accumulates toxins over decades.
- Overfished and not environmentally sustainable.
8. Imported Farmed Salmon (Certain Sources)
- Some imported farmed salmon may contain high levels of PCBs and contaminants.
- Choose wild-caught or certified sustainable sources instead.
✅ General Tips:
- Pregnant women, children, and frequent fish eaters should be especially careful about mercury.
- Look for sustainable seafood labels (like MSC or Seafood Watch) when buying fish.
- Smaller, short-lived fish like sardines, anchovies, and wild-caught salmon are safer choices.
