Blood egg

Ms. Bai, who lives in Qingdao, Shandong, reported that among the two bags of "insect eggs" she purchased from the supermarket, one egg had a red egg white. On the afternoon of March 4, a reporter contacted the manufacturer of the egg anti-counterfeiting technology. A responsible person surnamed Zhang said: "If only one or two eggs have this issue, it must be a special case because the hens are on their period and having menstruation." Dr. Ji Haifeng, an animal husbandry expert at China Agricultural University, stated that there could be two reasons for the blood-colored egg whites: one is that the hens were infected with E. coli which caused severe inflammation of the oviducts; the second is that problematic feed was added during the rearing process. Ji Haifeng said that hens do not have periods, and so-called "insect eggs" cannot be fed entirely on insects during the rearing process but may only have insect components added to their feed. It is recommended that citizens do not consume eggs with bloody whites.
