High levels of radioactive cesium have been detected in Japanese dairy cattle.
The Japanese newspaper Yomiuri Shimbun reported Thursday, that dairy cows at a farm in Iwate Prefecture, were found to be contaminated with cesium of, 541 becquerels per kilogram.
The limit is 5-hundred bequerels.
According to the paper, the prefectural government believes the contamination could be from cesium-tainted straw fed to the cattle.
Although several cesium-tainted beef cows have been detected in Japan since the nuclear plant meltdown in Fukushima Prefecture began, this is the first time that cesium has been detected in dairy cattle.
