Rumor Refutation：If there are spots on the egg shell, can we not eat it?

During storage and transportation, due to physical factors such as friction and collision, spots may also appear on the surface of the eggshell. These spots are usually caused by minute damages to the eggshell surface and do not necessarily affect the internal quality of the egg.

3. Impact of Storage Environment

The hygienic conditions of the storage environment also affect the formation of spots on eggshells. If the storage environment has high humidity, unstable temperatures, or significant microbial contamination, more spots may form on the eggshells.

These spots may be caused by colonies or metabolites formed by microorganisms reproducing on the eggshell surface.

How to Judge the Freshness and Safety of Eggs

To assess the freshness and safety of eggs, we can start with the following aspects:

• Pay Attention to Storage Time: Eggs have a relatively short shelf life, typically lasting about a week at room temperature.

• Observe the Appearance: Fresh eggs have smooth shells, uniform color, and no obvious spots or cracks.

• Smell the Odor: Fresh eggs should have a faint fishy smell when opened, which is normal.

• Check the Internal Quality: After opening the egg, observe the state of the yolk and whites. Fresh eggs have a full, bright-colored yolk that does not easily disperse, and the whites are sticky, transparent, and odorless.
