Just about any fish pulled out of the ocean will have some trace levels of mercury in it; but tuna, one of the ocean's biggest predators and one of the world's most popular fish, is uniquely suited to building up high stores of mercury in its tissues.

James Rogers, director of Food Safety Research & Testing at Consumer Reports, tells KNX pregnant women should be cautious and skip canned tuna altogether.
