The EPA study found only 5 percent of canned tuna samples contained mercury levels that exceeded the US FDA standards for safety. They are less stringent than the Environmental Protection Agency's.
So what's a tuna salad lover to do?
Study authors say they never said "don't eat tuna." They want consumers in high-risk groups to know you should limit consumption. High-risk groups include pregnant women, nursing mothers, women who may become pregnant and young children. They say consumption should be no more than two meals of light tuna a week or 6 ounces of albacore.
The National Fisheries Institute says there have been "no" cases of mercury toxicity from normal consumption of commercial seafood in any peer-reviewed study.
