The reason of stillbirth is that the temperature and humidity are not well controlled during hatching, the fertilized egg is infected by germs, or the embryo is abnormal. If the stillbirth is caused only because the temperature and humidity are not well controlled, such hairy eggs can be eaten, but the nutritional value is no different from that of ordinary eggs. Although some people think that hairy eggs may contain more nutrients than ordinary eggs due to ecological reorganization during embryonic development, there is no clinical test to prove it so far.
As for some people who say that hairy eggs contain active substances needed for life, including various vitamins and choline, eating them can enhance memory, nourish the brain, and is conducive to beauty and anti-aging, which is even more groundless. So far, there is no medical data to prove that hairy eggs have the above effects. Without the scientific data of medical experts as the basis, some folklore is unreliable.
According to the staff of the health department, there are not many stillborn eggs available for human consumption in daily life, and most of them carry germs, such as Escherichia coli, Salmonella, Staphylococcus, Salmonella and so on. , especially salmonella. About 80% of general food poisoning is caused by Salmonella, and besides Salmonella, hairy eggs may also carry pathogenic bacteria such as Escherichia coli and Staphylococcus. The reason why hairy eggs have a lot of germs is related to the physiological structure of chickens. Chicken reproductive system, urethra, anus and cloaca are all in one place, so fertilized eggs are easily infected by germs in excreta during fertilization. Once infected, there will be stillborn eggs. If some hairy egg embryos are left for a period of time after they stop developing, the protein inside can also produce a variety of toxic substances after decomposition.
In addition, the high content of estrogen in hairy eggs will have a certain negative impact on the growth and development of teenagers. People who eat regularly can also cause endocrine disorders. Therefore, from the perspective of food safety, it doesn't matter if you don't eat raw eggs.
