1. King Mackerel
- High in mercury, which can affect the nervous system.
- Avoid, especially for kids and pregnant women.
2. Shark
- Large predator fish accumulate mercury and other toxins over time.
3. Swordfish
- Another large predatory fish with high mercury content.
4. Tilefish (Gulf of Mexico)
- Known for very high mercury levels.
5. Bigeye Tuna
- Common in sushi; high mercury, particularly in raw or sashimi form.
6. Marlin
- Predatory fish with high mercury accumulation.
7. Orange Roughy

8. Chilean Sea Bass (Patagonian Toothfish)

9. Bluefin Tuna

10. King Salmon (Farmed)

Tips for Safer Fish Consumption
- Opt for smaller, younger fish like sardines, anchovies, or wild-caught salmon.
- Check origin and certifications (like MSC or ASC) for safer, sustainable options.
- Limit high-mercury fish to a few times per month or avoid altogether if pregnant or nursing.
- Diversify your seafood to reduce risk of contaminant exposure.
