Okay, here's something that's been bugging me for a week and a half now. I noticed that all the grocery stores in London stock their eggs on shelving, and not in refrigerated cases. Every grocery store I have ever been in in the US sells the eggs refrigerated. So here's what I want to know: (1) Is it safe to store eggs at room temp? (2) If so, why do stores in the US bother to refrigerate? (3) If not, why aren't the British dropping dead in droves? (4) What explains this strange difference in grocery customs? (5) How do grocers in other countries store eggs?
I know in the grand scheme of things these questions are hardly of vital import, but they're bugging me, and I'd love to have some answers.
