Eat Fish Often? Calculate Your Mercury Risk Now

 

FishIt's well known that eating seafood contaminated with mercury is a threat to human health, and particularly to pregnant women and children. A campaign has been started by Gotmercury.org and the Turtle Island Restoration Network to protect the public from these toxic effects.

Even the Food and Drug Administration (FDA) warns pregnant women, children and women who might become pregnant to avoid eating certain fish species because of their excessively high levels of methylmercury. These include:

  • Swordfish
  • Shark
  • Tilefish
  • King mackerel
  • Tuna (reduce intake)

A major goal of the campaign is to reduce U.S. consumption of swordfish, tuna and other mercury-contaminated seafood. They state two primary reasons for this:

  • Mercury-contaminated seafood is a major public health concern.
  • Long-line fishing fleets that target swordfish and tuna also catch endangered sea turtles and other marine life, which is profoundly upsetting the ecological balance of the world's oceans.

There are no mercury advisories to warn consumers of this potential threat, so GotMercury.org has developed a calculator to help consumers gauge how much mercury they are eating. The "Got Mercury? Calculator" http://www.gotmercury.org/ can help you decide how much, and what type, of seafood is safe for you and your family. And, it's simple: Just enter your weight, the seafood type and quantity, and hit the calculator button. The online calculator will tell you whether your consumption exceeds the EPA's safe limit for mercury.

Dr. MercolaDr. Mercola's Comments:

In a perfect world, fish would be a near-perfect food. It's high in protein and full of essential nutrients and healthy fats. Unfortunately, nearly all fish are contaminated with mercury. And, because it rapidly bioaccumulates in the food chain, mercury is found in higher concentrations of larger, older fish and predatory species like shark, tuna and swordfish. If you eat fish often, to protect your health you should know how much mercury you may be eating based on your weight.

Now, there's an easy way to find out. The online mercury calculator at GotMercury.org is an excellent tool for consumers to find out if the seafood they're eating is exposing them to levels of mercury above the EPA's recommended limit.

For example, the site lists a recent study by Turtle Island Restoration Project about the mercury levels in swordfish. Some 68 percent of swordfish samples tested were above the FDA Action Level of 1 ppm mercury and 16 percent were more than 2 ppm -- more than twice the FDA's Action Level. The average mercury concentration found: 1.38 ppm, 38 percent higher than the FDA Action Level.

This calculator is likely to be an eye-opening experience for many consumers who don't realize just how much mercury is in the fish they're eating. But, even with the calculator to assess risk, I still wouldn't recommend regularly eating fish -- unless you are absolutely certain that it is free from mercury and other harmful toxins that are present in seafood (like PCBs and dioxin) and PBDEs.

At this time the only way to be sure is to have your fish lab tested. When you visit your supermarket, ask the fish handlers where the fish comes from. They may contact the manufacturer for you, otherwise contact them on your own and ask if their fish has been tested for mercury and PCBs.

Chances are high that is has not, which is why we did some extensive testing of our own. We tested fish from a company that takes salmon from the interior of Alaska and were delighted to find that it tested safe from mercury and PCBs. You can order the Alaskan wild red salmon from Vital Choice conveniently on our site. At this time it's the only fish I can safely recommend.

There's another option for obtaining the nutritional benefits of fish without risking the toxic effects of mercury, and that is regularly consuming high-quality fish oil. I have researched and tried many brands of fish oil, and I recommend Carlson's brand as it offers fish oil and cod liver oil with superior purity and freshness. It is purified to the highest standards to be free from mercury and other toxins and is made without chemical modification and processing.

If you are unable to find it in your local health food store, for your convenience we carry Carlson's brand fish oil and cod liver oil on this site.
