Radiation released from the Fukushima nuclear plant in Japan polluted some Japanese beef, according to media reports.AFP reported Wednesday meat from 11 cows at a farm near the no-go zone of the polluted area was found to be contaminated with six times higher than the legal limit of a radioactive substance called caesium.The meat had been shipped across the country and may have been already eaten.  Some media reports cited government officials as saying eating a couple of servings of meat with such a high level of radiation may not pose any health risk. The farmer reportedly admitted he fed the animals straw polluted with radioactive fallout.
