Another quake measuring 6.1 hits north Japan

Tokyo: An earthquake with a preliminary magnitude of 6.1 hit northern Japan on Saturday, broadcaster NHK said. The epicenter was not far from Japan's stricken nuclear power plant.

There was no tsunami threat and no immediate reports of injuries or damage, NHK added.

Kyodo agency reported that a change in the sea level may occur following the quake, but no damage is expected.

Japan has been hit by hundreds of aftershocks since a massive earthquake and tsunami smashed the northeast coast on March 11, triggering a nuclear power crisis.

Radiation level in milk, spinach high

Spinach and milk taken from farms near Japan's crippled nuclear plant exceeded government-set safety limits for radiation, the government said on Saturday, in the first report of food contamination from the accident.

The tainted milk was found 20 miles (30 kilometers) from the plant while the spinach came from a neighboring prefecture, Chief Cabinet Secretary Yukio Edano told reporters.

While the radiation levels exceeded the limits allowed by the government, Edano said that the products "pose no immediate health risk" and that further monitoring was being conducted on other foods. If tests show further contamination, Edano said food shipments would be halted from the area.

"It's not like if you ate it right away you would be harmed," Edano said. "It would not be good to continue to eat it for some time."

The spinach radiation level is about one-fifth of one CT scan, he said.

"We are doing our utmost efforts to ensure the health of our people," Edano said.

Nuclear reactors at the Fukushima Dai-ichi plant began overheating and leaking radiation into the atmosphere in the days after the March 11 earthquake and tsunami overwhelmed its cooling systems. The government admitted it was slow to respond to the nuclear troubles, which added another crisis on top of natural disasters which left an estimated more than 10,000 dead and displaced more than 400,000 others.

Emergency crews worked on Saturday to cool the reactors and fuel storage pools by spraying water and to restore electricity. Edano said the situation while bad was not growing worse.

"The situation at the nuclear complex still remains unpredictable. But at least we are preventing things from deteriorating," Edano said.
