Overnight eggs must be cooked before eating.

The reason is that if the eggs are not fully cooked, and the uncooked yolks are eaten overnight, the nutrients can easily harbor bacteria if they are not properly preserved, which can be detrimental to your health, such as causing gastrointestinal discomfort and flatulence. However, if the food (egg) is already cooked, and properly sealed and stored at low temperatures (generally refrigerated temperatures), it can be kept for up to 48 hours without any problem.

Fresh eggs are alive and need to breathe constantly through the air holes in their shells, so they have the ability to absorb odors. If it is mixed with garlic, leeks and other foods with bad odor during storage, then the eggs will have an odor that will affect the effect of consumption. Therefore, when storing eggs, care should be taken to isolate them from other foods.
