Inspection Results for Fishery Products (Marine Fish Species Caught off the Coast of Fukushima Prefecture and Freshwater Fish Species Caught in Fukushima Prefecture)
The percentage of samples exceeding the standard limit for radioactive cesium concentration (100 Bq/kg) was 57% for marine fish and 45% for freshwater fish during the period from April to June 2011, but the percentage decreased by half in one year after the accident. Since April 2012, inspections have been focused on the fish species in which radioactive cesium concentrations exceeding 50 Bq/kg had been detected, and the percentage of samples with radioactive cesium concentrations exceeding the standard limit is continuing to decrease. In particular, regarding marine fish, radioactive cesium concentration exceeding the standard limit was detected in only one sample in January 2019. The number of samples with radioactive cesium concentrations exceeding the standard limit is slightly larger among freshwater fish samples compared with marine fish samples.
