Chronological Changes in Inspection Results for Fishery Products
Inspections of fishery products have focused on the fishery products in which radioactive cesium concentrations exceeding 50 Bq/kg were detected in the previous fiscal year and major fishery products in relevant prefectures. Monitoring is conducted once a week or so in principle. The number of fishery product samples showing radioactive cesium concentrations exceeding the standard limit is decreasing gradually.
Analysis of inspection results revealed that radioactive cesium exceeding the standard limit was not detected in fish that migrate over a wide area in the ocean even immediately after the accident at Tokyo Electric Power Company (TEPCO)'s Fukushima Daiichi NPS. Since FY2015, there have been no samples of marine fish species caught off the coast of Fukushima Prefecture and other prefectures that contained radioactive cesium exceeding the standard limit.
Some freshwater fish caught in and outside Fukushima Prefecture still show radioactive cesium concentrations exceeding the standard limit even in FY2017, but the number of such fish is decreasing year by year.
