Though keeping eggs at room temperature is a perfectly good idea in Europe, because of differences in production practices, it can be very dangerous in the U.S. The reason comes down to how we treat one simple, very insidious little bug, salmonella, which can cause extreme digestive distress and even prove fatal.
You can keep fresh, uncooked eggs in the shell refrigerated in their cartons for at least four to five weeks beyond the pack date or about three weeks after you bring them home. Properly handled and stored, eggs rarely spoil. If you keep them long enough, they are more likely to simply dry up. But donât leave eggs out. Theyâll age more in one day at room temperature than they will in one week in the refrigerator. As soon as youâve cooled them, refrigerate hard-boiled eggs in their shells and use them within one week. When storing hard-boiled eggs, you may notice a gassy odor in your refrigerator. It may be more noticeable when you open the refrigerator infrequently.
