Did you know the Japanese use a special machine to wash and check the eggs for structural integrity? That is why they eat raw eggs so much. It’s very safe over there. Meanwhile in Germany, it is considered a good sign to have residual shit and feathers stuck to organic eggs. And this is where you start to deep dive into cultural differences between the continents.
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.
