Changes in Inspection Results for Fishery Products
Monitoring of fishery products has been conducted in particular focusing on fishery products which exceeded a radioactive cesium concentration of 50 Bq/kg or are the major products of the relevant prefectures. Monitoring is conducted once a week or so in principle. The number of fishery products exceeding the Japanese Maximum levels(JMLs) has been gradually decreasing.
Shortly after the Tokyo Electric Power Company (TEPCO)'s Fukushima Daiichi NPS Accident, approx. 30% of the fishery samples collected in (the sea neighboring) Fukushima Prefecture exceeded the JMLs. Such samples decreased afterwards, and there have been only four samples exceeding the JMLs since April 2015. Since September 2014, there have been no samples collected in prefectures other than Fukushima Prefecture that contained radioactive cesium exceeding the JMLs.
Some freshwater fish caught in and outside Fukushima Prefecture still showed radioactive cesium concentrations exceeding the JMLs even in FY2022, but there have been none since FY2023.
The JMLs refers to 100 Bq/kg, which has been applied since April 2012 (in FY2011, provisional regulation values were applied, but tabulation is based on the current standard for the purpose of comparison with the results in and after 2012).
