The government of Japan has already banned beef shipments from Fukushima and Miyagi Prefectures. Now Iwate Prefecture is being considered for such a ban after cows there have been found contaminated with cesium.
At least 12 prefectures are voluntarily checking their own cows. The national government is says it will cover the cost of the testing. It is now believed that at least 3,000 contaminated cows made it to consumer markets.
It is becoming very clear that the damaged Fukushima Daiichi nuclear plant has been, and still is, spreading massive amounts of cesium across Japan.
