Earlier quoted context omitted.
Here is a really good example of food differences between USA and Europe. Something as simple as eggs: http://www.thejournal.ie/refrigerate-eggs-usa-europe-1809120... TLDR: European regulations force more stringent regulations on producers of eggs; therefore eggs are cleaner and you can store them for weeks without refrigeration. IMHO they've also got a much nicer colour.
You can store European eggs for longer because they're unwashed, precisely because they're dirtier . It's a value judgement, and I don't think it should be regulated either way.
I am under the impression that European eggs are not refrigerated. My understanding is that once you refrigerate an egg, the membrane separates from the shell, requiring that you continue to refrigerate it, as the egg is no longer properly sealed. Since American eggs are refrigerated to begin with, you need to continue refrigeration.
