(Provisional translation) [16 March] Safety inspections of fisheries products on radioactive materials Sericulture and Horticulture Division, Gunma Prefecture The Gunma Prefectural Government conducted inspections on radioactive materials in the samples of landlocked salmon, whitespotted char and Japanese dace taken from 14 rivers, Japanese smelt taken from one lake, and ayu sweetfish taken from one fish farm in the prefecture. The result of the inspection, obtained on 16 March, showed that the level of radioactive cesium was below the provisional regulation value in all the samples. However, in response to implementation of the new Standard Limits on 1 April, the Gunma Prefectural Government and relevant Fisheries Cooperatives have consented to release Japanese dace caught in Nakuta River, landlocked salmon and whitespotted char caught in Imagawa River, Kenjo River and Nurukawa River, and not to serve such fish for consumption. The Prefectural Government and Fisheries Cooperatives also have consented to collect Japanese smelt caught in Akagi-onuma Lake, and not to serve them for consumption. 1.
