Yes in europe and other places eggs generally arent washed before being sold. And often they aren’t even sold in a refridgerator. this is not a problem, as the inside of the egg is protected in three ways: A cell-membrane around the white, a hard calcitic shell with proteins and breathing holes and a coating that makes the calcite less permeable for water and bacteria.
In the USA and Japan and other places, they think this is gross and industrially wash their eggs before they go to the consumer. This removes the outermost layer partially, allowing for ingress of bacteria, thus the eggs need to be refrigerated to remain safe.
Yes and a bunch of other stupid questions designed to string you along, until they resolve without actually being all that interesting.
