Cracks and Bacteria. Refrigeration, as well as proper cooking, can greatly reduce the chance of becoming sick from a small amount of bacteria, according to the U.S. Department of Agriculture. However, cracked eggs always contain higher levels of bacteria and may not be safe to eat.
Can you boil an egg with a crack?
Yes, you can boil a cracked egg. Just know that a small amount of the egg white may leak out into the boiling water and make a mess. If the egg has been cracked for a while (more than a day), please do throw it out rather than attempt to save it. Food borne illnesses are no fun.
