1. We Muslims don't eat livestock and poultry slaughtered in Slim, but generally need to be slaughtered by imam, who is actually the gatekeeper of dietary standards, which is actually a guarantee of food source hygiene.

not only that, we Muslims slaughter our own livestock and attach great importance to cleanliness. For example, when Hui people slaughter chickens, they should generally circle them about a week in advance, and they are not allowed to dig around to avoid eating unclean things such as feces. During the period of captivity, we have to feed greedy and clean food. We Hui people call this kind of chicken "empty chicken". For another example, when Uighurs in Xinjiang make local famous dish saute spicy chicken, they should pay attention to "clean raising" for a period of time before slaughtering the chicken, feed clean food and drink clean water, and keep the whole body clean before slaughtering it.

There is also the famous Hui food "Hand-grabbed Mutton", which is very clean from the beginning of raising sheep. You should choose clean and high-quality feed to feed them, and wear a halter for a period of time before slaughter, so as to ensure the cleanliness of the meat source.

on the other hand, the cleanliness of food sources is also reflected in the importance attached to the cleanliness of water sources. Although the living customs of the Hui people vary from place to place, they attach equal importance to the cleanliness of water sources. We Hui Muslims regard clean water as life, and we are absolutely forbidden to wash and bathe at the source of clean water, or throw unclean things; It is forbidden to build animal pens and build urinals near water sources; A manhole cover must be added to the top of the well, and you must wash your hands before drawing clean water. When the bucket is not in use, it should be hung upside down. In domestic wells, a layer of fine sand will be laid at the bottom of the well and then stones will be covered to achieve the purpose of filtration. If you go to the river to carry water and encounter dirty things flowing down from the upstream, you will wait for the water to flow for a hundred paces before drawing. This is called "water flows for a hundred paces".
