Can you eat an egg whose shell is moldy?
The mildew of the egg shell shows that it has been obviously contaminated and can contaminate the interior through the tiny pores of the egg shell. Eggs exposed to rain or moisture will wash off the protective film on the surface of the eggshell, causing bacteria to invade the inside of the egg and become moldy, resulting in black spots and mildew on the eggshell; eating this kind of eggs will cause harm to the human body and easily cause food poisoning.
There are many invisible holes on the surface of the eggshell, and bacteria are likely to infect the inside if the outer surface is moldy. The best advice is not to eat. If you really don't want to give up, you may beat the eggs into a bowl to have a look. If the egg yolk is still shaped, the egg whites do not change color, and the whole egg yolk does not smell strange, so it should be edible. But it is recommended not to eat it.
Eggs also have an expiration date. The shelf life of eggs is 40 days at 2: 5 ℃, 15 days at room temperature in winter and 10 days at room temperature in summer. The freshness and nutrition of eggs beyond the shelf life will be affected to a certain extent. If the storage time is too long, the eggs will deteriorate due to bacterial invasion, resulting in sticky shell, loose yellow and other phenomena.
