Radioactive cesium exceeding the government standard has been detected in shiitake mushrooms grown indoors in 2 cities in Fukushima Prefecture, about 60 kilometers from the troubled Fukushima Daiichi nuclear plant. This is the first detection of radioactive cesium exceeding the standard in produce grown in greenhouses in the prefecture since the nuclear accident.
The Fukushima prefectural government says 1,770 becquerels per kilogram of radioactive cesium was detected in mushrooms grown in Date City. The level is more than 3 times the provisional government limit of 500 becquerels per kilogram.
560 becquerels of radioactive cesium was detected in mushrooms from Motomiya City.
At least 157 kilograms of shiitake mushrooms from the 2 cities were shipped from early July through Friday to Tokyo, a supermarket in Fukushima City, and a local farmers’ market.
