Eggs in their shells are generally good for 3 to 5 weeks when properly stored in the refrigerator. This period starts from the time of purchase, not the pack date on the carton. Hard-boiled eggs last about one week in the fridge. It's best to keep eggs in their original carton on a shelf inside the fridge rather than in the door, as the temperature is more stable there. Refrigerators should be kept at 40°F (4°C) or below for optimal egg preservation. Eggs should not be left at room temperature for more than two hours in the U.S. due to bacterial risk. If an egg is cracked, it should be used within two days if refrigerated after breaking out of the shell. Cooking eggs actually shortens their shelf life compared to raw eggs in the shell.
