How much harm does a piece of pork do?

There is a saying in the supermarket that "fresh food is the locomotive of the store, and the meat department is the locomotive of fresh food". This shows the importance of the meat department in the store. This paper will analyze the calculation of gross profit of pork segmentation in stores from the source. Pork, known as "big meat" in some places in the north, is also the meat we consume the most. At present, there are many kinds of pigs, which are usually called native pigs, Yorkshire pigs, binary hybrid pigs and ternary hybrid pigs. Both of them are local pigs, and there are also variety differences in different parts of China. Not only in the same province, but also in different regions. For example, in Shaanxi Province, the pigs west of xi 'an are usually thicker and whiter with Xi 'an as the center. The pigs in the south of Xi 'an are small in size, reddish in meat color and good in taste. Due to the early introduction of foreign pig breeds in Sanyuan and Gaoling areas north of Xi 'an, the lean meat rate of pigs is relatively high although they have been crossed many times. The three-way hybrid pig produced by crossing local pigs with foreign pigs has the characteristics of strong disease resistance and high lean meat rate. The shape of this pig is very distinctive, as if it had evolved from a wild boar not long ago. The mouth is sharp and long, the figure is thin, the spine is sunken, and the ears stand like wolves. (Binary pig) (Sanyuan pig) There is a very interesting phenomenon. Most of the dividers in the north like to divide the meat with a knife, and most of the dividers in the south use a big knife to divide the pork. It is in great contrast with what we traditionally think of as the rudeness of northerners and the delicacy of southerners. People who sell meat generally have low cultural quality, but because selling meat is actually a high-tech job, people who sell meat are usually very flexible. Low cultural quality and flexible mind are the characteristics of people in this industry. There is a saying-"pigs are full of troubles." This is true, so the utilization rate of pigs is very high. Because pigs are full of troubles, there are many unsafe and disharmonious factors in the pork industry. It used to take a year to a year and a half to slaughter a pig, but now it can be slaughtered in half a year 10 months. Various chemicals play a great role, such as hormones. Moreover, there are many diseases in pigs, such as foot-and-mouth disease and blue ear disease, so the growth of a pig cannot be separated from a large number of veterinary drugs, especially antibiotics. Someone invited the author to eat wild boar, which really tastes different from domestic pork. (Wild boar spirit) Many pigs have to be injected with water before they are bought back by slaughterhouses. A water tube is inserted into the stomach and water is pumped in. The flooded pig will die if it doesn't buy it within two hours. The cruelty and treachery of black-hearted farmers also gave birth to the cunning of slaughterhouses, which often don't weigh pigs, but only pay according to the net meat weight after slaughter. (Sick pig-miserable? There are often pork suppliers (slaughterhouses) who say that the price of pork (half a pig) he supplies to the supermarket is the same as the price he buys, thus resisting the bargain-hunting in supermarket procurement. After investigation, it is true that the supply price he gave us to the store is basically the same as the net meat settlement price for the pig collector. So where does the profit of pork suppliers (slaughterhouses) come from? In fact, for every pig slaughtered in a slaughterhouse, the slaughter fee can be 5~ 15 yuan. That's not enough. There is an unwritten rule in many places that pig's head and pig's trotters (viscera) should be returned to the slaughterhouse. So the pork supplier (slaughterhouse) in the store earns water money. Large slaughterhouses can provide half a piece of red stripes (with fat removed) or white stripes (with fat removed), then these slaughterhouses can also get pigskin as a welfare, and a pigskin can be sold for at least 100 yuan.
