Researchers say Bluefin tuna, found off the Pacific coast, may contain radioactive material.
Scientists believe the tuna were contaminated by radioactive material from the nuclear meltdown at a power plant in Japan following the earthquake that rocked the country in 2011. Those fish then migrated 6,000 miles to the California coast.
When tested, the tuna contained radiation levels ten times higher than normal.
Despite that, scientists say the levels are still well below what’s safe for human consumption.
