Why is chicken butt poisonous?

In fact, in many places, not only in my place, it is believed that the chicken butt is poisonous, can not be eaten, and there are people who say that "chicken butt is arsenic". So, for the chicken butt poisonous this saying still exists. Why? It is related to the above mentioned two structures on the top of the chicken's butt, one is the caudal fat gland, and the other is the suprachiasmatic sac.

First of all, the caudal fat glands are close to the anus, very easy to come into contact with chicken poop and other pollutants, and this part of the body is often pecked at by chickens, which will inevitably cause inflammation in the area, and thus infected with bacteria and viruses and even lead to the blockage of the glands, so this part of the body is very unclean. In addition, if the tail fat gland is not removed, it is also easy to cause other meat contamination, because the tail fat gland will carry a kind of foul smell.

Secondly, the supracavitary capsule is the central lymphatic organ of the chicken's humoral immunity, which is filled with many macrophages. We should also know that macrophages are used to swallow germs and viruses in both humans and other avian animals. So the supracapsular sac above the chicken's buttocks is undoubtedly a concentration camp for bacteria and viruses, which often contains a large number of bacteria and viruses that have not been decomposed, as well as other cellular debris, metabolic wastes and other substances, and even a lot of toxins and carcinogens deposited here. Therefore, for those chickens that have been raised for several months and are ready to be eaten, the supracavitary sac above the chicken's buttocks has undoubtedly become a large warehouse where viruses, germs, toxins, and carcinogens are stored. In addition, in veterinary medicine, this suprasellar bursa is also known as the bursa, and bursitis has always been a high incidence of disease in avian animals, so if this part of the body is diseased, it will be more likely to accumulate some bacteria and viruses.

All of the large lymphoid organs of some poultry animals are not recommended to eat, because some of the toxins contained in this material, even after high-temperature cooking, especially like some thermophilic bacteria, it is very likely not to be killed, and if people eat it naturally harmful to the body.

Therefore, in many people's places there are people who think that chicken ass race arsenic, chicken ass is poisonous, must not eat.

But every time I tell my chef friend that chicken butt is poisonous and can't be eaten, he always says, "What do you know? He would always say, what do you know, as long as the chicken butt clean, that is, you said the chicken butt above the tail fat glands and the cavity of the sac cut off, clean, then there will be no chicken butt poisonous things. You have only heard of "chicken ass race arsenic", but have you also heard of "would rather give up the gold mountain not to give up the chicken tip", the chicken ass is a rare delicacy on earth, very tasty, you do not eat that is too wasteful!
