high levels of radioactive cesium in fish caught early this month off Hitachi in Ibaraki Prefecture

Researchers have found high levels of radioactive cesium in fish caught early this month off Hitachi in Ibaraki Prefecture, northeast of Tokyo.Prefectural officials said 1,037 becquerels of cesium were discovered per kilogram of Japanese sea bass.  That's more than 10 times the government safety limit.They said it is the 3rd highest level found in marine products in the region.  Higher levels were only previously detected in April 2011 -- one month after the Fukushima nuclear accident.  The contaminated fish then was sand lance.The officials said the sea-bass shipment will not hit the market as it does not meet government restrictions.They admitted they don't know why such a high dose was detected more than 2 years after the accident.But they said they are working hard to keep the food supply safe.  Jul. 11, 2013 - Updated 18:05
