Coastal Women Have Highest Mercury Levels
Mercury harms the brain of developing children, which is why health officials aim to warn women of childbearing age to eat a variety of seafood and to limit consumption of high-mercury fish such as tuna.
Because it's hard for a one-size-fits-all health advisory to really tell a woman how much tuna she can eat, EWG used federal data to assemble our Tuna Calculator, where you can plug in your weight and find out how much tuna you can safely eat per week.
