Results of the monitoring on radioactivity level in fisheries products

In accordance with the “Concepts of Inspection Planning and the Establishment and Cancellation of Items and Areas to which Restriction of Distribution and/or Consumption of Foods concerned Applies,” the Fisheries Agency, in cooperation with the relevant prefectural governments and organizations, has been regularly conducting monitoring of radioactive materials in the fishery products at the major fishing ports in Fukushima and adjacent prefectures since the accident of Fukushima Daiichi Nuclear Power Station (FDNPS) of Tokyo Electric Power Company following the Great East Japan Earthquake in 2011.

At a total of 159,419 fishery product samples has been monitored (as of January 27, 2021) since the FDNPS accident. The result represents a significant trend that the radioactive cesium excess ratio has decreased and recently very few fishery products exceed the Japanese maximum level (100Bq/kg).

As of 25 February 2020, shipment restrictions were lifted for all marine fish species and thereby they are traded at the market without any radiological restrictions in Japan.
