Between October 12 and November 8 our team, led by Greenpeace Japan Oceans Campaigner Wakao Hanaoka, took seafood samples from the same five supermarket chains - Aeon, Ito Yokado, Uny (Apita), Daiei and Seiyu - [DW1] as featured in the first round of research, taking 15 samples from each. Of the 75 samples, radioactive cesium 134 and 137 were detected in 27. There was no company whose products were not contaminated.
The Pacific cod wasn’t the only contaminated fish we found. Cesium 134 and 137 were detected in all five samples of Bigeye tuna we took and in all five samples of Skipjack tuna.
Although the level of contamination was not very high (4.6 Becquerel per kg), there is no detailed information about the fish’s origin such as where it was caught and what type of mackerel it is. The label on the can simply says “made in Japan”. The government's labelling regulation for canned fish and processed fish products is far less stringent than for fresh fish products and needs to be addressed immediately.
We can only hope that government agencies can remain as vigilant over other contamination that has been spread so widely across the country.
so there it is, no food is safe in a tin even....
