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.
A colleague of mine from Japan explained to me, that salmonella sit on the outside of the shell. When you crack the egg open, the salmonella can enter the egg white. By washing the eggs, you get rid of salmonella but make it more susceptible to other bacteria, which are usually less harmful.
