USDA Recommends 7-Day Refrigeration Limit for Hard-Boiled Eggs to Ensure Safety
The U.S. Department of Agriculture (USDA) advises that hard-boiled eggs, whether peeled or unpeeled, should be consumed within seven days of cooking and stored in the refrigerator. This guideline is crucial for preventing foodborne illnesses, as cooking eggs creates a thin layer of moisture under the shell, which can foster bacterial growth. The clock for this seven-day period begins the moment the eggs are cooked, not when they are peeled. Furthermore, cooked eggs must be refrigerated within two hours of coming out of the pot, or within one hour if the ambient temperature is above 90°F (32°C). Failure to adhere to this two-hour rule invalidates the seven-day storage recommendation. The USDA emphasizes that while cooking kills initial bacteria, it does not protect the egg from spoilage indefinitely, making proper and timely refrigeration essential.
