Whether the egg tart can be eaten overnight depends mainly on the preservation method and ambient temperature. If the egg tart is sealed with plastic wrap and put in the refrigerator for the night, it can usually be eaten. Because the temperature drops under cold storage conditions, the egg tart is sealed with plastic wrap to isolate the air. Although egg tarts that are sealed and refrigerated overnight can also be eaten, it is best to heat them thoroughly in the microwave oven before eating. In addition, it is recommended to finish eating as soon as possible.

If the egg tart is placed in a high temperature environment, such as summer, indoors, because the egg tart is made of eggs and other ingredients, and staphylococcus is often easy to infect eggs and egg products, staphylococcus can multiply at 37℃ and produce enterotoxin. Therefore, it is suggested that when the temperature is high, egg tarts or other foods should be kept in the refrigerator.
