Generally, the shelf life of fresh eggs is different in different seasons. It is about three days at room temperature in summer and relatively low in winter, so it is about 15 days indoors at room temperature in winter. If eggs are stored in the refrigerator, the shelf life will be longer, about 40 days.

Moreover, the environment also has a certain influence on the storage of eggs. If it is not stored in the refrigerator, it should be made of clean paper or cloth and stored in a dry, cool and ventilated environment to prevent deterioration, such as yellowing and cracking due to direct exposure to air.

For boiled eggs, the storage time will be shorter. Cooked eggs will not spoil the taste of eggs in a short time, but it is recommended to eat them within one day.

You can judge whether an egg has expired in the following ways:

1, listen to the voice:

To judge whether a raw egg has gone bad, you can pick it up and shake it in your ear. If the egg can shake back and forth, it means that the egg and eggshell are separated, so the egg has gone bad.

2. In the water:

To judge whether an egg has gone bad, you can put it in water because the egg has many holes. If the egg sinks into the water, it means that the egg is good. If it floats on it, it means that the egg is bad.

3. Smell:

To judge the quality of an egg, you can break it and smell it. If the egg smells bad or musty, it means that the egg has gone bad and is not recommended to eat.
