Food
Immediately after the accident at Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant in March 2011, the Government of Japan had taken comprehensive actions, such as establishing provisional regulatory values, monitoring of foods and materials for agricultural production, restriction of distribution of food with higher radionuclide levels than the regulatory values, and decontamination of farm land in order to ensure sufficient supply of safe foods distributed Japan, including foods to be exported. In April 2012, new limits were established for foods on a basis of intervention exemption level of 1 mSv/year, equivalent to the Codex Standard and monitoring results accumulated.
Since April 2012, the results of monitoring has indicated that the excess rates are decreasing and extremely low, 0.1% in FY2018, and majority of the detection (exceeding cases) is limited to wild harvest monitored at area where the distribution is already restricted. Non-compliance cases are hardly detected in food commodities prepared for the market. Estimations of exposure (effective dose) to radioactive cesium in foods are decreasing constantly and now around 0.1% of 1 mSv/year.
Japan continues to make utmost efforts for prompt and accurate information sharing regarding this issue. Also, Japan intends to respond to this issue in close cooperation with the relevant international organizations.

- Monitoring of radionuclides in food are mainly conducted before shipment. Most of the food items exceeding the limits are derived from areas where restrictions of distribution have been instructed. Non-compliance cases are hardly detected in food commodities prepared for the market.
