Dried Anpo persimmons from Fukushima Prefecture are famed for staying fresh and juicy. However, for the second successive autumn, 90 percent of the crop has had to be discarded due to it registering radioactive contamination levels above legally set limits.

Mushrooms, a staple of Japanese cuisine, have now been found with unacceptable levels of radioactive cesium as far away from the Fukushima No. 1 nuclear power plant, whose explosions and three reactor meltdowns caused the contamination, as Aomori and Nagano prefectures — several hundred kilometers away.

It is clear that the dangers lurking in the food we eat in this country have by no means been eliminated.
