11/28/2011, they found out that rice distributor, Keibeimiyagi Association, used deceptive labeling on the origin of the rice.
They labelled Fukushima rice as Miyagi rice, they also labelled unchecked rice as Aomori rice or Miyagi rice.
They also found out that Kenbeimiyagi does not keep book accounting properly, they kept the transactions very unclear. It makes the traceability system of food meaningless, which violates the law of traceability.
Kenbeimiyagi explains it was merely a mistake, not on purpose.
