1. "Freckled eggs".

Brown spots visible to the naked eye on the surface of the eggshell, some even slightly raised, are called "freckle eggs", which are formed by the uneven distribution of calcium and eggshell pigments.

Because the color of the eggshell and the stage at which the material inside the egg is formed, these "spotted eggs" are not linked to bacterial contamination and can be eaten.

2. "Dark Spotted Eggs".

There is a darker watermark or band on the bottom of the eggshell, which will appear slightly darker than the average egg, called a "dark spotted egg" or "bottom spotted egg".

"Dark eggs" are caused by the accumulation of moisture in the eggshell near the eggshell through the less flexible eggshell membrane, and is not related to Salmonella contamination.

3. Microbial invasion.

There are many pores on the eggshell, and if it is stored for too long, bacteria, mold and other microorganisms may drill into the holes, and when they spread to a certain extent, plaques will form on the surface of the eggshell.
