If in doubt, smell your eggs:  If you have any doubt as to whether or not your egg is safe to eat, smell it.  Eggs that have gone bad have a “Sulphur” or rotten smell to them.  That shouldn’t be your only guide, however. Eggs that have been outside the refrigerator for a few hours may not have developed the smell quite yet, but they still aren’t safe to eat.
