Let me also mention this article from Asahi Shinbun on April 30. It was on a local section of Shizuoka Prefecture, but I found that they making a total lie about the EU safety standard. I was shocked but it made me really angry!
This article talks about komatsuna (Japanese mustard spinach) being refused to be imported in Singapore because it exceeded safety limit over there.
Here's a link to the article (in Japanese)
The article says,
"The safety standard in Singapore is stricter than that of Japan and the EU….."
and
"The amount of Iodine 131 that was detected in komatsuna there was 648 Bq/Kg. It surely exceeded the Singaporean safety standard of 100 Bq/Kg, but it is 2,000 Bq/kg than that of Japan and the EU."
Then, I got suspicious about the EU safety standard, but did not think Asahi Shinbun, the major newspaper, could so straight lie about other country's safety standard…..then, I learned that they did. As you can see in my list, the EU safety standard of Iodine 131 is 150 Bq/Kg for children (food) and 500 Bq/Kg for adults (food). I realized that Asahi Shinbun just wanted to make it like it was all Singapore's fault of making such a strict standard. It seems to be that the Singaporean standard is all so normal to me.
Whoever wrote this article, please explain to me that you are not making a lie on this. I still like to believe there is some true journalism left in the Japanese media. There is no way of making a lie when you are talking about something related to people's life….right?
