The 12 Most Contaminated Fish to Avoid in the Supermarket

11. Garnet perch
The garnet perch can live up to 150 years, so it has more time to accumulate mercury and other toxins in its body. This deep-sea fish is threatened with extinction due to overfishing.

12. Grouper:
Groupers are susceptible to ciguatera poisoning – a foodborne illness caused by eating reef fish contaminated with toxins. Groupers also have a high mercury content.

Final Thoughts:
Fish can be a healthy part of your diet, but it’s important to choose wisely. Stick to low-mercury options like sardines, wild salmon, or cod. Always pay attention to where your seafood comes from and opt for sustainably caught fish if possible. By avoiding the most polluted species, you can enjoy seafood without putting your health at risk.
