Female pork is poor in nutrition and tasteless. What's more serious is that the female pork contains immunoglobulin, which is harmful to human body, especially in sows before farrowing. Eating raw pork is easy to cause diseases such as poor preparation, hemoglobinuria and hemolytic jaundice, so it must not be eaten. Therefore, it is necessary to find out the basic characteristics of female pork and identify it carefully to prevent it from being bought and eaten by mistake.

The sow skin is thick and yellow (it can be brushed off with bleaching powder), with deep and large pores and tufted "small" hairy roots, especially on the back. Therefore, sow skin is often stripped by sellers and sold as skinless meat. Fat pork, on the other hand, has thin skin, fine white skin and shallow pores. The nipples of sows are long, thick and hard, so they are often cut off. The adipose tissue of sows is yellow and dry, and it seems to contain sand particles when it is kneaded vigorously, and it is separated from the muscles. The fat of fat pork is dense, tender and white. The stripes of sow lean meat are rough and dark red; However, the lines of fat pig lean meat are short and clear, water-red, and watery and tender. The pork ribs of sows have a large curvature, and the ribs on their backs are prominent, yellow and thick. The bone marrow of sows is dirty red, and there is yellow oily liquid oozing out; There is no yellow oily liquid in the bone marrow of the pig. The sow's belly is one to two times larger than that of the pig, and it looks dry outside, unlike the pig's belly, which has a slippery mucous membrane outside. The sow has a big head, a long mouth, long fangs on both sides of the mouth, and thick and flat trotters. Female pork is very old and does not boil easily. Eating raw pork is easy to cause diseases such as poor preparation, hemoglobinuria and hemolytic jaundice, so it must not be eaten. The pig skin of female pork is thicker than that of ordinary pig skin, and the pores are thicker. The hip skin has a concave pit with a large grain of rice, and the meat is rough and fishy. Especially the lean meat is dark red, which is darker than the meat color of general fattening pigs and lean pigs; Abdominal muscles are slack, and muscle and fat layer are easy to peel off; The meat in the breast is fine, soft and wrinkled, and the mammary glands are atrophied. Some female pork skins have a reddish or red layer between them and subcutaneous fat. Eating less is not harmful to the human body, so don't be too nervous, just don't eat in the future. Good luck!
