That earthquake damaged the Fukushima Daiichi nuclear power plant, triggering radiation emissions that contaminated waters off the Japanese coast. Now a study published in the journal Proceedings of the National Academy of Sciences states that bluefin tuna caught near San Diego in August 2011 contained elevated levels of radioactive cesium-137 and cesium-134.
It’s believed the bluefin swam through the contaminated waters before migrating across the Pacific Ocean.
However, the study also says the radiation levels found in the tuna, while higher than normal, fall well below U.S. Food and Drug Administration health risk limits. At this point, it appears a wasabi bomb may pose a greater immediate threat to sushi lovers.
But the presence of radioactive materials in the bluefin plus the arrival of earthquake and tsunami-related marine debris upon the coasts of Washington and California concerns Rep. Edward J. Markey (D-Mass.). He’s sent the FDA and NOAA letters asking the agencies about their efforts to ensure seafood safety and protect public health.
”The importance of our seafood stocks and the jobs they support require vigilance when monitoring the half-life of radiation present in fish and marine debris,” says Markey, a Natural Resources Committee member and senior Energy and Commerce Committee member, in a press statement. “We need to understand the environmental and human health implications of the Fukushima disaster on Pacific seafood, and I look forward to responses from these two agencies.”
