Tainted milk was found in Fukushima prefecture while contaminated spinach was discovered in neighbouring Ibaraki prefecture, chief government spokesman Yukio Edano told reporters.

The milk was found more than 30 kilometres (20 miles) from the plant, beyond a government exclusion zone.

But Edano urged consumers to remain calm, saying that even if a person were to drink the contaminated milk for a year, the radiation level would be the equivalent of one CT hospital scan.

"The government will do its utmost... to avoid health hazards and to resolve this problem," he said.

Abnormal levels of radioactive iodine were found in the water supply in Tokyo and several prefectures near the power plant, a science ministry official said.

Traces of radioactive caesium were also found in tap water in Tochigi and Gunma prefectures, but the levels of both elements were well below the legal limit, the official said.
