Stinky eggs are eggs that turn green and black in color and smell bad, which may be harmful to your health and should not be consumed. These eggs are usually caused by a variety of microorganisms that gradually invade and multiply inside the egg, breaking down the nutrients in the egg and causing it to rot and deteriorate. They may contain a variety of pathogenic bacteria such as Salmonella, Aspergillus, and E. coli, and may also contain harmful substances such as hydrogen sulfide, indoles, nitrates, nitrites, amines, and mycotoxins, which may affect human health. If you eat rotten eggs, they may have certain toxic effects on the human liver and digestive system, leading to a series of poisoning symptoms such as nausea, vomiting, abdominal pain and diarrhea. In addition, harmful microorganisms such as mold and bacteria that grow in rotten eggs can lead to disease, and carcinogenic substances such as nitrites can pose a cancer risk to the human body. Therefore, if you find eggs that turn black or green and smell bad, throw them away in time. There are many small holes in the eggshell that cannot be seen by the naked eye. In warm and humid conditions, moisture in the air can enter the egg through these holes. Therefore, when storing eggs, you should pay attention to the right temperature and keep them dry, and avoid storing them in humid and warm places to avoid deterioration. In addition, if you buy eggs that are dirty, take care not to wash them so as not to damage the external egg shell membrane, which is more conducive to the invasion of bacteria and microorganisms and accelerates egg spoilage.
