How Could Radiation be Found in Food Exported from Japan?

Ray Hearn sends in an interesting question about the radiation scare that is currently heading around the world. It seems that food from Japan has been found to have radiation it it.


From the BBC: 

Japan investigation into nuclear plant radiation leak

“Singapore's Agri-Food and Veterinary Authority said it had found small levels of contamination in Japanese mustard, parsley and two other plants imported from the prefectures of Tochigi, Ibaraki, Chiba and Ehime.”


Interesting... Wait a minute! Ray asks a poignant question:

"So how did these plants get picked, processed, packed, delivered to an international airport or shipping port and then get to Singapore from the supposedly infected areas when the roads where out and the country in lockdown for virtually all of the last two weeks?

Maybe things were functioning better in Tochigi, Ibaraki, Chiba and Ehime than they were in Tokyo for the past 14 days.

Anyway just a thought."


Yes. A very interesting thought. How could this have happened? 


As we know, even a banana has natural radiation in it. You also might be familiar with the old saying "Those who go searching for trouble, usually find it." It's true. Now the panic has reached such a pitch level that it is claimed that these foods from Japan or people going through detectors at foreign airports shows trace radiation levels. 


I suspect some sort of anti-Japanese business shenanigans going on and some more mass media hype adding fuel to the fire. Any other thoughts?
