It looks like the nuclear accident is so behind them in Japan, rat or no rat. Ministry of Health and Labor announced that the radioactivity testing for food items will be scaled down significantly, by exempting 34 items from testing.
That's 25% of food items that have been regularly tested since the start of the Fukushima I Nuclear Power Plant accident.
They have been testing only 132 food items to begin with.
What's puzzling is that certain fruits that have consistently been found with elevated amounts (if not exceeding the safety standard of 100 Bq/kg) of radioactive cesium are going to be exempted - peaches, apples, and pears.
From Kyodo News (3/19/2013):
Testing for radioactive cesium in food to be scaled down, Ministry of Health and Labor says
On March 19, the national government announced that certain leafy vegetables, fruits, and certain kinds of fish will be exempt from the tests conducted by the municipalities for radioactive cesium, starting April. The number of food items to be tested will be reduced from the current 132 to 98. It is the first time that the radiation test for food has been significantly revised.
The reason given by the ministry is that radioactive cesium is not detected any more in increasing number of food items.
For example, the items to be excluded from the testing are spinach, lettuce, cabbage, daikon, potatoes and others for the vegetables, peach, apple, pear and others for the fruits, young lancefish, sardine, mackerel, yellowtail and others for the fish.
Well, as you know, peaches, apples, pears and persimmons from Fukushima will be sold to Thailand as "gourmet fruits" for the rich. JETRO just announced that Malaysia will no longer require the radiation test certificates for the food items from Japan. Rich Malaysians will get to eat those "gourmet fruits", too.
Information at the website of Ministry of Health and Labor is as clear as mud. You can't readily tell which vegetables, fruits and fish have been exempted by the Nuclear Disaster Response Headquarters. You have to know exactly what they have been testing (132 items) to know what will be exempt, as the ministry's press release only confirms what are still to be tested.
