Can an uncracked egg have salmonella?

Yes, uncracked eggs can have Salmonella. Salmonella is a type of bacteria that can cause foodborne illness and is found in the intestines of animals, including poultry and other birds. When a hen is infected with Salmonella, the bacteria can be present on the outside of the eggshell, even if the shell is not cracked. This is why it's important to wash your hands after handling raw eggs and to cook eggs until the yolk and white are firm.
