Grocery chain operator Ito-Yokado says it sold over 2,600 kilograms (5,732 pounds) of beef contaminated with cesium.  The beef was sold at 94 outlets in Tokyo and several surrounding prefectures, as well as on the northern island of Hokkaido, between April and July.

Ito-Yokado is not the only store that has admitted to selling the contaminated beef.  Two other grocery/department store operators, Seiyu and Isetan Mitsukoshi Holdings, have admitted to selling the meat.

Consumers are being asked to bring the meat back, but many analysts think that too much time has gone by and that most of the beef has been eaten.
