On June 4th, 2013, London-based news source the Guardian reported, “Fukushima tuna safe to eat – study.” The day before, the Los Angeles Times reported, “Scientists to eaters: Don’t freak out over Fukushima fish.” The San Diego Union-Tribune was emphatic: “Tuna Pose No Risk after Nuke Disaster,” and online, “Fukushima seafood radiation risk nil, study says.” The BBC ran with, “Fukushima tuna pose little health risk.” And CNN declared, “Fukushima tuna study finds minuscule health risks.”
So which is it? Does that sushi or canned tuna pose a minuscule risk, just a little one, or is it safe? The Proceedings of the National Academy of Sciences published a report online May 30, 2013 that garnered these vastly disparate headlines. The NAS team studied measurements of cesium-137 and cesium-134 in Bluefin tuna caught off the California coast. The cesium was dumped or leaked as liquids into and deposited as gaseous fallout on the Pacific Ocean from Fukushima’s three catastrophic reactor meltdowns. The poisoned tuna swam 5,000 miles to our West Coast.
