The tainted milk was found 20 miles (30 kilometers) from the plant, a local official said. The spinach was collected from six farms between 60 miles (100 kilometers) and 75 miles (120 kilometers) to the south of the reactors.
Those areas are rich farm country known for melons, rice and peaches, so the contamination could affect food supplies for large parts of Japan.
More tests was being done on other foods, Edano said, and if they show further contamination, then food shipments from the area would be halted.
Officials said it was too early to know if the nuclear crisis caused the contamination, but Edano said air sampling done near the dairy showed higher-than-normal radiation levels.

Too early to know of the nuclear crisis caused the contamination? Really?
