The Miyagi Prefectural government announced that cesium levels in rice grown in Kurihara had been found contaminated up to 240 becquerels of cesium per kilogram. Kurihara is mostly farmland, mostly known for its rice fields, and small mountain ranges dispersed throughout. The prefectural government announced that it will prevent nearby rice farms from shipping their produce to the markets for sale.
According to the Ministry of Agriculture, Forestry, and Fisheries, the elevated levels of cesium may have been elevated due to the fact that the farmers plowed the fields without completely removing the weeds that had been growing, increasing the contamination levels in the soil.
Miyagi Prefecture has been one of the three most affected prefectures by the Fukushima nuclear disaster. During the March 11th earthquake, Kurihara was the only city to report a maximum value of 7 on the Japan Meteorological Agency Seismic Intensity Scale.
