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.
The results of monitoring conducted after April 2012 indicate that the violation rates are extremely low, much less than 1%, for agricultural products including cereals, vegetables and fruits, meat and milk, fish and fishery products and edible fungi grown on media. Estimations of exposure (effective dose) to radioactive cesium in foods are decreasing constantly and now less than 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.
