FUKUSHIMA, Japan (AP) -- Contamination from Japan's tsunami-crippled nuclear complex has seeped into the food chain.
Health officials say radiation levels in spinach and milk from farms near the facility exceed government safety limits. But the officials insist the small amounts of radiation -- with traces also found in tap water in Tokyo -- pose no immediate health threat.
Meanwhile, the government says the situation at the Fukushima Dai-ichi plant, while still unpredictable, appears to be coming under control after near-constant dousing of water to prevent spent fuel rods from burning up.
Emergency teams using an unmanned vehicle to spray water targeting the most at-risk of the plant's six reactors launched a new round Sunday, aimed at the plant's Unit 4.
Crews are also preparing to switch power back on for the first time since a March 11 earthquake and tsunami knocked out the plant's crucial cooling systems.But there's no guarantee the cooling systems will still work.
