Tokyo officials say they found beef, shipped in from Fukushima Prefecture, is contaminated with high levels of cesium.

On 08 July 2011 the beef tested positive for 2,300 becquerels per kilogram of cesium, the national safe limit is 500 becquerels per kilogram.

The beef came from cows raised in Minami Souma, in Fukushima Prefecture.

Japan’s Health Ministry says this is the first time such high levels of radiation showed up in beef.  They are now requesting the six prefectures around the Fukushima Daiichi nuclear plant, to increase testing their cows for radiation.
