Can you eat overnight eggs?

Generally, whether leftover cooked eggs can be consumed depends on the storage method and the condition of the eggs. If the eggs were fully cooked and promptly refrigerated without signs of spoilage, they can be reheated and eaten. However, if the eggs were left overnight in their raw state, were not refrigerated after cooking, or show signs of spoilage, they should not be consumed. It is recommended to carefully check the condition of the eggs before eating to ensure safety. Detailed explanation is as follows:

If the eggs are fully cooked, stored in a sealed container in the refrigerator within 2 hours after cooking, and refrigerated for no more than 24 hours, they can generally be consumed after reheating thoroughly using a steamer, microwave, or similar method until the center is warm. Low temperature inhibits bacterial growth, and thorough reheating eliminates potential safety risks, thus posing no harm to health.

Raw eggs left overnight, cooked eggs not refrigerated promptly after cooking and left at room temperature for a prolonged period, or eggs showing signs of spoilage such as an off odor,黏连 (adhesion) of yolk and egg white, or a slimy surface should not be consumed, as they may cause gastrointestinal discomfort such as bloating and diarrhea after consumption.

To ensure food safety, raw and cooked eggs should be stored separately to avoid cross-contamination. Leftover cooked eggs should be refrigerated promptly and sealed properly to prevent odor absorption. Before consuming leftover eggs, ensure thorough reheating and inspection of their condition; if any abnormalities are observed, discard them immediately.
