In a major find that may make maguro sashimi an even rarer delicacy, scientists have discovered that radioactive bluefin tuna have been crossing the Pacific Ocean without shedding the radiation.
Following the magnitude-9 earthquake last March, and the ensuing tsunami damage to Japans' Fukushima Dai-ichi reactors, a team decided to test Pacific bluefin to compare radiation levels.
The results? Levels of radiation were 10-times higher than in previous years; AP reports that the tuna is still far below safety limits. Still, researchers were "frankly kind of startled" that the tuna could travel some 6,000 miles and still fail to completely flush out the radiation.
