Sampsonite,
The issue on radiation and food has been discussed on this forum before and all you have to do is to search keywords for threads. So I'm just sort of repeating it all, but here goes.
Long story short, I don't think the government is lying, but at the same time they're not doing a very good job on this issue. But then, I can't really blame everything on them. This is something no one has experienced, plus there just isn't enough tools and manpower to monitor/organize everything.
For example, contaminated beef is being found even in Matsusaka (and is officially announced) because the cattle was fed on contaminated hay that had leaked accidentally. At the same time, from Chernobyl we have learned that a small amount or less frequent consumption of radioactive substances won't affect humans (although infants and the unborn are more sensitive).
So it's all a matter of how much you want to avoid "accidents" and how much amount or frequency you want to consider as "risks." For example, a friend who lives in Fukushima says she tries not to feed her teenagers with Fukushima products although the parents consume whatever is sold. I think that's important, in a way, because in Fukushima you also have to consider the air contamination you are exposed to.
Either way, you are free to avoid anything you want, and what you chose not to avoid is what you "believe" in. Some may prefer to believe in renowned brands as they honor reputation. Some may prefer to believe in organic restaurants as they honor good farming. There are also restaurants who deliberately serve and support Fukushima products while posting charts proving that all producers they handle personally monitor their own products.
And mind you, as soon as the society widely discovers something new, either the government or municipal does work on it. For example, only a few out of many cattles had been tested up until recently, but prefectures up north (Miyagi, Yamagata, Akita, Niigata) has decided to test every single cattle they sell as meat.
http://mainichi.jp/select/jiken/news/20110726ddm041040060000c.htmlhave you as a local or anybody else for that matter changed your eating habits since March?I eat and have been eating every single thing that is served to me outside my house, meaning at restaurants and friends' homes. So does my teenager.
At home, I buy from an organization that says they've started monitoring all their vegetables. I also buy almost any tasty-looking vegetable in which the farmer's name is open to public. That way, I know where it's coming from, and plus, good-looking fresh products tend to have good nutrition, and good nutrition will help you build a healthy body that can fight radiation.
Also not that when making your order to eat or buy something, you don't have to hesitate to ask where it's coming from. Everyone understands your anxiety. For example, a shop I always buy from would gladly research if I ask where each vegetable from their mixed pickles are coming from. Or when I'm standing at a shop thinking if I should buy a piece of fish, the shopkeeper would tell me it's from a certain place in the south, and that would make me feel easier.
But then, what
can you trust? The media is all about Fukushima at the moment keeping an eye on them, but we can't forget the fact that there are nuke plants all over the world which people don't even pay attention to. And there are lots of polution or fraud or what not going on, and we can't really say that just because a piece of food is from another certain country it's safe.
All in all what I
believe in is to
maintain health rather than to
avoid risks.
By the way, I don't understand what "special tags on products in S/M" are. What is "S/M"?
