The Japanese government on Tuesday suspended all cattle shipments from Fukushima prefecture due to fears of radiation-tainted beef in the country's meat distribution chain.

The suspension came after the discovery that about 650 cows, which were suspected of being contaminated with radioactive cesium have been shipped to at least 38 of Japan's 47 prefectures.

The shipments of beef cattle from all parts of the northeastern prefecture were suspended until requirements for lifting the ban are met.

The radioactive cesium was believed to have originated from the troubled Fukushima Daiichi nuclear power plant which has been leaking radioactive substances following the March 11 earthquake and tsunami.
