Should Mercury-Filled Canned Tuna Be Legal?

Low in fat, high in protein, and filled with omega-3 fatty acids (which protects against heart disease and stimulates brain activity), canned tuna is a wonder food on paper. Until it starts making your hair fall out.

As Mother Jones reports, Deborah Landvik-Fellner ate canned albacore tuna daily for 12 years until her hair started falling out and her speech started slurring. When she got her blood tested, frightening results came back: it had 48 parts per billion of mercury, nearly ten times the Environmental Protection Agency's notion of "safe."

Shouldn't tuna be labeled if it's so dangerous? The Tuna Foundation sure hopes not. They know mercury scares will cause sales to plummet. In 2005, tuna companies launched a $25 million campaign to counteract the FDA's advisory. They ran full-page newspaper ads touting tuna's on-paper perks ("Tuna: A Smart Catch") and used celebrity doctors as endorsement bait. Do mercury levels in canned tuna scare you? Or do you eat it anyway?
