A government report released on Tuesday revealed elevated levels of radioactive cesium in locally grown mushrooms from Japan‘s Yamanashi prefecture. Specifically, a sample of the edible Cortinarius caperatus mushroom from Narusawa village in the prefecture exhibited a cesium level of 150 becquerels per kilogram (Bq/kg).
This exceeds the permissible cesium limit for general food products in the country, which is set at 100 Bq/kg. The testing was conducted on October 15, and the affected mushroom did not reach the market.
The Ministry of Health, Labor and Welfare routinely discloses test results on radioactive substances in food products from 14 prefectures in north and east Japan, a practice established in the aftermath of the Fukushima No. 1 nuclear power plant incident.
