The Environment Ministry said Monday it detected 61 to 2,600 becquerels per kilogram of radioactive cesium in 23 varieties of freshwater fish sampled at five rivers and lakes in Fukushima Prefecture between December and February.

After the Fukushima Daiichi nuclear plant crisis, the government reduced the level of radioactive cesium deemed safe for consumption to a maximum of 100 Bq/kg for fish, meat and other food items.
