Japan’s government is calling on farmers not to use or sell compost and humus made in the east of the country since the start of the Fukushima nuclear crisis.
Radioactive cesium exceeding the government’s permissible levels has been found in rice straw sold by dealers in Miyagi and other prefectures.
The agriculture ministry wants a voluntary ban on the use and sale of compost made of manure from cows that may have been fed the contaminated straw. The measure also applies to humus from fallen leaves.
The ministry says the ban should continue until it draws up guidelines for levels of radioactive cesium in compost.
