if might be prudent to stock up on powdered milk, butter, sour cream powder, and eggs NOW while non-contaminated supplies are still available, as well as lay in as much water as you can store. You can use tap water. If your city has already been hit, check out how to clean it of radiation: https://earthchanges.ning.com/profiles/blogs/how-to-make-safe-drinking.
Remember, it takes 20-something gallons of milk to make a pound of butter, thus butter will have a higher concentration of radiation. You can buy it powdered (still in stock at beprepared.com) or you can buy it fresh in the store and can it yourself. Recipe is at http://www.endtimesreport.com/canning_butter.html. In the alternative, if you don't use butter, stock up on extra virgin olive oil. It has a very long shelf life.
Note: beprepared.com is currently backordered on both milk and eggs. However, if they are backordering it, they expect to get more in. Get in line NOW, because as Fukushima continues to spew the line is going to get longer and eventually the new supplies will be contaminated.
I have used beprepared.com for over seven years. They consistently have the best overall price, ship quickly (except for backlogs, but those do come once they get the products), are very quick to follow up on problems (they once misdelivered my order to someone else and they quickly replaced it), and I think they are a good, ethical outfit.
