Fukushima Prefecture, Japan, has order its own ban on Shitake mushrooms after a sample tested positive for contamination.

Iodine and cesium were found on mushrooms grown outdoors in the city of Iwata. No contamination found on indoor grown mushrooms. Iwata is 40 kilometers (24.8 miles) from the Fukushima Daiichi nuclear plant.

The radiation levels are higher than safe limits set by the national (central) government. It was the local government that set the ban on shipping the contaminated mushrooms, after no order was heard from the central government.
