Summary. 1  Fish that contain high levels of mercury include shark, orange roughy, swordfish and ling. 2  Mercury is a naturally occurring element that is found in air, water and food. 3  The unborn baby is most sensitive to the effects of mercury, particularly during the third and fourth months of gestation.
But some types of seafood â particularly large, predatory fish such as shark, swordfish, king mackerel and tilefish â can contain high levels of mercury. Although the mercury in seafood isn't a concern for most adults, special precautions apply if you're pregnant or planning to become pregnant. If you regularly eat fish high in mercury, the substance can accumulate in your bloodstream over time.
