Eggs aren’t refrigerated in Scottish grocery stores, and they don’t need to be refrigerated at home.
In America, eggs go through a washing and sanitizing process that clears contaminants, but also removes the natural protections that eggs have against bacteria, Insider’s Kelly Burch reported. This requires eggs to remain refrigerated to reduce the risk of salmonella.
In Europe, eggs don’t go through this sanitization process, so they don’t require refrigeration. The UK also vaccinates chickens against salmonella.
As an American, I wasn’t used to seeing eggs shelved next to canned goods and dried fruit instead of in the refrigerated section.
