The reporter learned from experts in the animal quarantine department that the custom of eating hairy eggs spread from the south to the north. It is only a legend that "hairy eggs" are nutritious, but in fact, dead sperm eggs mainly form dead embryos in the process of hatching chickens because of temperature, humidity, salmonella infection and parasite pollution. Nutrients such as protein, fat, sugar, inorganic salts and vitamins contained in eggs are mostly consumed by the development of embryos during incubation. Even if you can leave a little nutrients, you can't compare with fresh eggs. Because the eggshells of most hairy eggs have been broken, they are easily contaminated by bacteria. According to tests, almost 1% of hairy eggs can detect Escherichia coli, and some also detect staphylococcus, typhoid Bacillus and Proteus. If you eat that kind of heated and polluted hairy eggs, it will cause abdominal pain, diarrhea, nausea, vomiting, etc. Eating hairy eggs can almost be said to be harmful rather than beneficial.
