According to the Reuters news agency, the World Health Organization sees the situation around the radioactive contamination of foodstuffs in Japan as more serious than originally believed.
The Organization is specifically concerned about exports from the Fukushima prefecture, where the damaged nuclear power plant is located.
A negligible quantity of radioactive particles has already been found in milk and spinach.
The Japanese Health Ministry has advised the Fukushima, Tochigi and Gunma prefecture residents against drinking tap water. Iodine and cesium isotopes are slightly above normal in 9 out of Japan’s 47 prefectures.
Meanwhile people in rain-hit Tokyo prefer to stay inside for fear of nuclear fallout.
