This week, radioactive tuna from Japan made its way through international waters and into local parts of the Pacific Ocean. The pack of migrating bluefin tuna fish swam thousands of miles, carrying hazardous levels of radioactive cesium–the result of last year’s tragic earthquake and tsunami in Japan, which caused extreme damage to nuclear reactors. And while radioactivity is worrisome, this is just one more reason why choosing sustainable, safe sushi and other seafood products is more important than ever.
The amount of cesium found in the bluefin is relatively small–and eating it once or twice won’t cause you to glow, or immediately trigger the growth of tumors all over your body. But you’d be wise to avoid bluefin and other forms of unsafe, unsustainable tuna, anyway, for a multitude of reasons.
Bluefin is already Japan’s most expensive edible fish–and in the hunt for fish that have somehow haven’t been tainted by the nuclear exposure will only drive up the price, which is reason enough for most of us regular folks to order something else. However, bluefin has bigger fish to fry than a little cesium: Â itÂ is also seriously overfished (because of its popularity), and on the verge of collapse as a species. But if even that hasn’t stopped the supply and demand, a little nuclear waste won’t, either; there’s a good chance that unscrupulous fishers who are looking to make money regardless of safety concerns may continue to pump it into the supply of edible food.
And while the news of radioactivity is likely going to land bluefin on a lot of people’s “don’t eat” list (at least for the next few months), it’s not the only fish in the sea that’s raised red flags for its significant health risks. Â Aside from the widely-acknowledged problem ofÂ high levels of mercury found in many tuna products, the seriously saddening amount of garbage in the ocean,Â and overfishing that is threatening the balance of the ocean’s ecosystem,Â there are the unsavory, unsafe processes that fish undergo before they end up on the table.
“Tuna scrape,” which is made by removing the fat and tissue from the spine of yellowfin tuna, and often used in spicy tuna and other sushi rolls, recently got in some hot water after it was found that large quantities of it were handled and stored improperly, and may have sickened dozens of people with Salmonella. The imported, ground-up fish goodÂ isn’t exactly pink slime–but it also hasn’t undergone enough research to truly know that it’s safe.
So what’s a seafood lover to do, when marine populations are being depleted and replaced with nuclear waste and garbage, and fish products are continuously being recalled for safety issues?
Easy: go back to basics, and think before you eat, purchase, or order any kind of seafood. The simplest way to make sure you’re eating the good stuff is to check with the Monterey Bay Aquarium Seafood Watch, one of the most reliable and comprehensive lists of seafood rankings, based on safety and sustainability. They even have a special guide just for sushi. You can find the pocket guides at aquariums and even seafood counters across the country, or check them out online. They even have an app in the Android and iPhone stores.
Safe seafood may seem like a mystery, but there if you’re armed with resources, you’ll be able to order fish that’s good and good for you–come hell or high, nuclear-tainted water.
