Tuna Surprise

Since doctors advise pregnant women and women of child-bearing age to limit their tuna consumption, because eating tuna may put their unborn baby at risk for mercury poisoning, I assumed everyone knew the hardcore scoop about tuna. Not so. Famed food writer, Mark Bittman discusses in the New York Times that he did not know the source of mercury poisoning. He asked the experts, and after talking with Moms Clean Air Force senior director, Dominique Browning, Bittman connected the dots between the air spewing out of coal-fired power plants and the tuna fish swimming in our waters.

If you’re like most people (including me, up until a month or two ago), you know that tuna and other top-of-the-food-chain fish contain unsafe levels of mercury and that childbirth-age women and nursing mothers, especially, are warned off these fish. What you don’t know, probably (I didn’t), is the mercury’s source, or how it gets in these fish.

Turns out that about three-quarters of it comes from coal-burning power plants; it dissolves in water, where micro-organisms convert it to methylmercury, a bio-available and highly toxic form that builds up in fish. The longer a fish lives, the more mercury builds in its flesh.

You could, of course, eat less big fish, but there are other sources of mercury: increasingly, it’s being found in vegetables and especially grains like rice that are grown near older, and even no longer functioning, coal-burning plants.

It’s another of those situations where individual solutions don’t really cut it, because mercury is only one of about 80 (!) pollutants spewing from old-fashioned, unfiltered coal-burning plants[1]. And some of the toxins, which are deadly, are just plain unavoidable. Because, unlike mercury, they’re not in tuna and rice. They’re in the air.

It was for these reasons that the journalist (and mother) Dominique Browning started Moms Clean Air Force. “When I was a young mother,” she says, “and was told not to eat tuna, I didn’t make the air-to-food connection; but it’s outrageous that these issues are still being fought 21 years later. I was neither an environmentalist nor an activist, but I could no longer ignore important issues.” ~ Mark Bittman 

You would think all this mercury polluting would cause an outrage – enough to put pressure on the power companies — the ones we pay to provide us with electricity, so they would stop polluting our children with mercury. We did and we won with new Mercury and Air Toxics Standards. But now the rule is being contested in courts by some of the worst polluting utilities in the country.

How dare these polluting utilities sue to protect their right to spew toxins into our air!

What’s a tuna-lovin’ mom to do? No tuna sandwiches for my family for now. And I won’t sit idle while our children are poisoned by sickening lawsuits. Which is why I’m asking you to join thousands of parents who signed this petition telling polluters to fund clean air, not lawsuits!
