yes, mercury is an health issue !
I don't think there is much mercury in canned tuna - because it is usually small fishes - but eating tuna every day is not very safe
About 8 percent of American women of reproductive age have enough mercury in their blood to cause concern, research released Tuesday suggests.
Methylmercury is a neurotoxin and can cause developmental damage to fetuses, researchers noted.
"Overall our conclusion is that measures of mercury exposure generally fall below levels of concern," said Susan Schober, senior epidemiologist at the Centers for Disease Control and Prevention. "However, 8 percent of women had concentrations higher than the U.S. Environmental Protection Agency's recommended dose."
Just when people are being told fish can benefit their health, researchers have associated higher blood mercury levels with fish consumption. Schober said eating fish just three or more times 30 days before the data were collected quadrupled the mercury levels women had in their blood.
Schober told United Press International women who are pregnant or planning on having children should follow federal and state government guidelines on fish consumption.
The study, published in Wednesday's issue of the Journal of the American Medical Association, reported blood mercury levels in children between ages 1 and 5 "generally fall below levels of concern."
The Food and Drug Administration suggests women of reproductive age should avoid shark, swordfish, tilefish and king mackerel, according to an advisory issued in 2001. Schober said because these fish are at the top of the fish food chain, they tend to accumulate more mercury than others.
Another fish that accumulates mercury is large tuna, said Thomas Burke, health policy professor at the Johns Hopkins School of Public Health in Baltimore.
