6. Spanish Mackerel
This is another mackerel that’s contaminated, and like the King Mackerel, it’s due to its large size. The Atlantic Spanish Mackerel is another migratory fish that goes to the Northern Gulf of Mexico in springtime and returns to south Florida, then the Western Gulf of Mexico in the fall. Even with this migratory pattern, they can be found from the Yucatan of Mexico all the way to the Cape Cod of Massachusetts.
Spanish Mackerel are actually related to tuna. They can grow to three feet in length and because they live more closely to the shores, they can easily become contaminated by mercury that is being released into the ocean via slow moving coastal rivers.
7. Orange Roughy
Orange roughy, which are part of the slimehead family (sounds tasty, right?) can take as long as 40 years to reach full maturity. Amazingly, these fish can live as long as 150 years! This means that, besides being easily overfished, they have many years to accumulate mercury and other toxins into their flesh. Orange roughy live in the deep waters off the Western Pacific Ocean, Eastern Atlantic ocean, South Africa, New Zealand, Australia, and the Eastern Pacific off Chile. Although they are actually a deep brick-red color, their flesh fades to a yellow orange after death, hence their name.…show more content… Regular consumption of orange roughy can have seriously adverse effects on your health. On top of that, compared to other fish, orange roughy is not a good source of omega-3 fatty acids, so you would be wise to choose another type of fish.
