The "Got Mercury?" calculator at www.gotmercury.org or on your mobile phone www.gotmercury.mobi helps you make healthier seafood choices by estimating exposure from eating tuna, sushi, fish.

Mercury contamination of seafood is a widespread public health problem. The Food and Drug Administration warns that pregnant women, nursing mothers, women who might become pregnant, and children should not eat swordfish, shark, tilefish, and king mackerel because of their high methylmercury content. The FDA also warns women and children to limit their consumption of tuna.

Seafood low in mercury can be part of a healthy diet. However, seafood consumers should eat a variety of fish low in mercury and should have a balanced diet.

GotMercury is a project of Turtle Island Restoration Network, the parent organization of Sea Turtle Restoration Project.
