New Independent Fukushima Food Contamination Results

polimasterdetectPeople in Japan early on realized they needed to take things into their own hands if they wanted to know the conditions around them and what their risk factors were. Citizen labs have been set up in Japan to allow people to test their own food. These labs were modeled after the labs set up in Europe after Chernobyl. This has provided an independent confirmation against government testing and a more diverse set of readings. These local labs focus on the food available within a region, even allowing people to test foods from their own gardens to determine if they are safe to eat.

While the government in Japan (and elsewhere) have insisted anything below legal intervention levels of food contamination are “safe”, the public and many NGOs have disputed this. Ongoing problems with cesium in children’s urine belies the govt claim that all is ok. Two sets of standards have evolved. The one the government uses and the one the public uses to scrutinize their food supply.

In recent months the government food testing program has turned their focus towards food items that are known to have little or no contamination along with some periodic widespread screening of things like beef. This leaves considerable holes in the understanding of contamination levels in food. We gathered readings from a variety of citizen run labs across Japan. These also include a few readings for non-domestic sources including soil from Vancouver. Out of the readings that were frequently positive are citrus fruits, that were found to be contaminated along with persimmons and kiwi fruit. There were also many negative, no contamination findings for foods including those in Fukushima. We did not include those for brevity but can be found in the reports linked to in the positive findings. Soil and moss from the Setagaya area of Tokyo were found to be contaminated. Wood stove pellet ash from Gifu was found to be contaminated. Gifu was assumed to not have been significantly contaminated from the disaster. Miyagi sourced wood pellets gave a considerably higher reading. Both wood pellet samples were burned at homes near Tokyo, showing how our widely distributed consumer system for products can bring contaminated products to other areas.
