Continuing inspections of rice crops are revealing how pervasive the radiation contamination is.  Three more farms have been found to be contaminated above safe limits.

The result is that the national government, on 05 December 2011, banned rice shipments from 406 farms.  The farms are located in several districts within the cities of Fukushima and Date, in Fukushima Prefecture.

The latest rice farms to make the list are 60 kilometers (37 miles) from the Fukushima Daiichi nuke plant.
