Hairy eggs are “chicken embryo eggs” formed when the embryonic development stops due to the influence of temperature and humidity during the incubation process, or due to Salmonella infection or parasite contamination. Hairy eggs can be divided into live fetal eggs and stillborn eggs, which have low nutritional value and are at risk of pathogenic microbial infection. Although the eggs themselves are rich in nutritional value, most of them have been consumed during the incubation process, so the nutritional value of live eggs is low. On the other hand, stillborn eggs are infected by bacteria and parasites and terminate hatching, which can lead to a large number of germs in the eggs, such as E. coli, S. deformans, S. typhi and Staphylococcus, and produce a lot of ammonia, nitrogen, methane and other harmful substances, which may not play a supplementary nutritional role after human consumption, but may also cause poisoning and gastrointestinal diseases, especially for children and adolescents, and have a greater impact on Especially for children and adolescents, it has certain harmful effects on physical development. Therefore, it is usually not recommended to consume woolen eggs, especially those that are not thoroughly processed and do not meet the requirements of killing viruses, bacteria and other pathogenic microorganisms. If you must consume raw eggs, you should be careful to ensure that they are sterilized at high temperatures and cooked to perfection to help reduce the risk of eating them. It is generally recommended to choose fresh eggs, which contain a large amount of protein, phospholipids, amino acids and other nutrients, as well as selenium, zinc, iron and other trace elements, which play an important role in human growth and development.
