High levels of radioactive cesium have turned up in beef from cattle raised in the region of Japan’s damaged nuclear reactors. Japan’s government has mandated an expansion of its meat monitoring program, reports MSNBC.

The Tokyo metropolitan government said this weekend that testing had detected radiation levels of three to six times the legal limit in beef from 11 cows shipped to Tokyo this month from Minamisoma city, located just outside the 20-mile no-go radius around the Fukushima Daiichi power plant.
