Consumers are starting to hoard last year's rice over concerns the next crops may be contaminated with radioactive materials released from the Fukushima No. 1 power plant, retailers said Friday.

The Agriculture, Forestry and Fisheries Ministry is working to establish a system for ensuring the safety of rice ahead of the autumn harvest, with plans to inspect the crop in two stages.

The buying spree indicates deep public distrust in the government's handling of food safety issues amid the nuclear crisis following a scare over contaminated beef.
