Japan nuclear crisis: fears over food contamination

Fears that radioactive particles could have contaminated food and milk supplies have eclipsed progress made towards averting a potentially-catastrophic nuclear meltdown at the Fukushima Daiichi reactors.(ibm thinkpad t40 battery)
Engineers have managed to rig power cables to all six reactors at the Fukushima complex, and restarted a water pump that will help reverse the overheating that triggered the world's worst nuclear crisis in 25 years.(Acer aspire 3000 battery ) A spokesman for Tepco, the plant operator, said workers had to be briefly evacuated after light grey plume of smoke was spotted emanating from reactor three but added radiation levels had remained stable.
He said: "We are checking the cause of the smoke." ( dell vostro 1400 battery )A small quantity of smoke was still coming out nearly two hours later, but engineers were reported to have resumed work
Engineers at the Fukushima Daiichi facility, 155 miles northeast of Tokyo, had been racing to restore power to cooling systems at its six reactors to reverse the overheating that triggered the world's worst nuclear crisis in 25 years. (sony vgp-bps3 battery)
In the meantime, fire trucks are spraying water to help cool reactor fuel rod pools.
Asked if the worst of the nuclear crisis was over, Steven Chu, the US Energy Secretary Steven Chu, said: "we believe so, but I don't want to make a blanket statement." (hp pavilion dv8000 battery)
Gregory Jaczko, the US nuclear regulatory commission chairman, added that radiation levels at the site appeared to be falling.
But mounting concerns that radioactive particles already released into the atmosphere could have contaminated food and water supplies eclipsed the progress made in the battle to avert a catastrophic meltdown in the reactors. (dell inspiron 1545 ac adapter )
Concern about radiation has spread to food and Japan's Chief Cabinet Secretary Yukio Edano, ordered a halt to all shipments of spinach from the four provinces surrounding the plant. Milk shipments from the province of Fukushima were also banned.(ibm thinkpad x40 battery)
The contamination also spread to other vegetables – canola and chrysanthemum greens. Tokyo's tap water, where iodine turned up Friday, now has caesium as well. Rain and dust are also tainted.
In the province of Ibaraki, a centre of vegetable production, tests found radioactive iodine levels in spinach that were 27 times the accepted limit. (dell inspiron 1525 battery)
Milk in Fukushima was found to be contaminated with radiation 17 times that limit.
The Japanese government said the levels were still far below anything that would cause harm to human health. (dell inspiron 1545 ac adapter )
Mr Edano said: "Even if you eat and drink them several times it will not be a health hazard. So I would like you to act calmly without reacting."
But a World Health Organisation official said the situation was "more serious" than originally thought.
Peter Cordingley, the Manila-based spokesman for the WHO's regional office for the Western Pacific, said: "Quite clearly, it is not what we thought in the early stages. It is more serious. (hp pavilion dv2000 battery)
"We have seen Japanese people in grocery stores paying close attention to where their produce is coming from, and we think this is a wise practice." (hp pavilion zv5000 battery)
Meanwhile, the World Bank said rebuilding may cost £145 billion following the earthquake and tsunami which is thought to have killed more than 20,000 people.
