Japanese eatable fishes could have very high level of radioactive cesium

Map of Japan with highlighted Fukushima prefectureResearchers of Environment Ministry have found a mountain trout in the river of Japan, near Fukishima nuclear disaster, containing 114 times more radioactive cesium than the permitted level by government. They found 11,400 becquerels of radioactive cesium per kilogram, when the maximum permitted level for food items is 100 becquerels per kilogram.

The Environment Ministry has surveyed the fishes and their cesium levels for the second time since the disaster in March last year.

“Like the previous survey, concentrations (of cesium) tended to be higher in rivers and lakes than in the sea. We want to grasp the extent of pollution by continuously conducting the survey,” a ministry official said in a statement.

Researchers found a catfish with 30 times the permitted limit of cesium and a smallmouth bass with 44 times the permitted limit.
