Three farms in the city of Date, Japan, harvested rice that was found to be contaminated with cesium, up to 1,050 becquerels per kilogram.

Earlier in November as many as six farms in Oonami district were found with contaminated rice.  Those farms did not sell their rice, but the farms in Date did.

Now officials are trying to track down who bought the cesium contaminated rice.

Date, and Oonami are in Fukushima Prefecture, where the Fukushima Daiichi nuke plant continues to emit high levels of radiation.  Originally officials were testing rice just from the 154 farms in Oonami, but will now test more than 2,300 farms in the prefecture.
