When we were in Australia and New Zealand, I could not help but notice that they don't refrigerate the eggs for sale in the grocery store. Looked at me like I had two heads when I asked them why. My husband is from Mexico and they never refrigerate eggs there, either. But, when I was in Greece last year they do refrigerate theirs. I've talked to friends who "grew up on the farm way back when" and they said they went by the rule that you could leave them out unless they had been in the fridge for a time. In other words, once they were in there they couldn't be taken out and left on the counter. But, if you took them directly from the hen you could leave them out and they would be fine. I've read a few comments on here that say you can leave them out for like 10 days, but surely in places like Oz and NZ, they can't sell everything they collect in 10 days? Heaven knows our eggs at the grocery store are older than that. Is this just yet another cultural thing? Just wondering.
