The Asahi Shimbun reported Friday that a greenling fish caught in a port near the nuclear plant on Feb. 17 was found contaminated with radioactive cesium levels 5,100 times above the Japanese government's standard, according to Tokyo Electric Power Company (TEPCO).
TEPCO said the reading of 510,000 becquerels per kilogram in the greenling is the highest ever recorded in the utility’s seafood sampling surveys following the March 2011 earthquake and tsunami at the nuclear plant.
A rockfish caught Feb. 15 in a cage net along a wharf in the port produced a reading of 277,000 becquerels per kilogram, said TEPCO.
The company put up a net in the harbor to trap contaminated marine life after detecting the higher-than-normal levels of cesium in fish and shellfish caught in the port.
The harbor seabed has been contaminated with radioactive substances since the disaster.
