Salmonella on eggs is really a US thing. It’s not so much inside the egg as it is on the outside of the shell. The cracking and opening of the egg can contaminate the egg inside. Since it is not cooked to 155 degree Fahrenheit the salmonella survives your stomach acid due to a tough outer shell which then goes to work inside your body.
The EU for example does not wash their eggs and can even leave them outside of the refrigerator. The membrane that is washed away in the US protects the egg from bacteria.
