Radioactive food is becoming a real and hidden concern. The discussion of this is veiled and brief on NHK TV news, the national broadcaster. One might assume that NHK is avoiding promoting a food panic. Already prices for Hokkaido dairy products are increasing. Previously in this blog, radioactive mustard spinach, a very popular part of the Japanese menu, was discovered growing in Tokyo weeks after the 15th March explosion, and in mustard spinach imported to Singapore from Shizuoka (south of Tokyo). Now some people are concerned that rice being grown in the north may be mixed with uncontaminated rice grown in the south. According to NHK, already, rice stocks are low, as many people are stocking up ahead of the harvest season beginning now. A friend of mine went shopping in Nagoya city with a dosimeter (a radiation measuring device) and found that cucumbers in his supermarket had high levels of radiation. I wish I could get a dosimeter, they are so hard to get.
