39 bags (57.5 kg) of rice from the 1100 Bq/kg farm have been sold. The prefecture ordered the recall of the bags. This is the second occurrence of contaminated rice being sold. Until now 38 rice farms in 3 cities and one town have been found above safety level.
In 2012, rice planting in the areas that harvested rice contaminated between 100 and 500 Bq/kg in 2011 will be subject to conditions such as low risk (when the number of samples found above 100 Bq/kg was small) and decontamination measures, the Fukushima Central Union of Agricultural Cooperatives announced. Concerning the areas where rice was not grown in 2011, the conditions will be set after the full test results of the 2011 harvests are known. The Fukushima Central Union of Agricultural Cooperatives also said that in 2012, 100% of the bags will be tested, and whenever a radiation, even a small one, is detected, they will not be shipped. The ministry of agriculture indicated at the end of last year its intention to restrict rice planting in the areas where crops higher than 500 Bq/kg were harvested. Concerning the areas where crops were found between 100 and 500 Bq/kg, the policy will be decided after consulting with the prefecture and growers.
The ministry of health announced that the detection threshold for general food testing that is to be applied from 1 April, is set at 25 Bq/kg instead of the present 50 Bq/kg. Public comments on this measure are open till 13 February.
Nagano prefecture has started testing each mushroom growing farm. The 600 farms will be tested until March.
(Chugoku Shimbun, 26 January morning edition) Professor Toshihiro Takatsuji of Nagasaki university announced at an international symposium at Hiroshima university on 25 January that high radiation levels were found in Nagasaki one month after the accident. The Cs 134 concentration on paper filters was 11,300 Bq/kg during the week from 6 April 2011. Using US National Oceanic and Atmospheric Administration data, he found that on 6 April, the southern half of Japan was blown by winds from Tohoku. He said that even if the atmopheric radiation value is low, it is possible that it increases in locations where radioactive substances accumulate, such as on air conditioner filters.
