The biggest harm of eating pig's head meat comes from the possibility that it is a dead pig.
We usually hear more about swine fever. This disease is a multiple infectious disease. Once a pig in the farm is infected, soon the pigs in the whole farm will be infected one after another, causing huge losses. In order to recover some losses, some unscrupulous farmers will sell dead pigs at low prices and let them flow into the market. Eating such pork is very harmful to human body. So keep your eyes open when you buy, and don't hurt your body because you are greedy and cheap.
In addition, pig's head meat is a pathogenic thing, and people with excessive wind and evil can't eat it, and people with chronic diseases such as hepatitis and tuberculosis can't eat it.
If you are unfortunate enough to suffer from the above diseases, you'd better stop eating pig's head meat from now on for your health.
