Regarding food safety:
People should eat cooked, drink boiled and choose to buy pork at establishments that meet food hygiene and safety conditions. Absolutely should not eat blood pudding or rare, raw meat, because although it is not contagious and dangerous to people, it should not be misunderstood that it can be used to process infected pork. When buying meat, it is necessary to pay attention to choose pieces of meat with bright pink color, soft skin, meaty texture and good elasticity. When pressed, do not leave sticky dents. In particular, fresh pork is red or dark red, the outer membrane of the meat is dry, but when cut with a knife, the color is normally bright. Do not choose pieces of meat that are low in fat, loose, and have a strange color change, and when pressed with your hands, the meat feels greasy.

To ensure safety, consumers should choose to buy at establishments that meet food hygiene and safety conditions.

Regarding the sanitation of the barn:
Farms and livestock equipment must strictly control people and animals entering and leaving the breeding area; cages must be easy to implement measures of hygiene, sterilization and disease prevention; There should be nets around the cages and other measures to prevent insects and other vectors from transmitting diseases such as mice, birds, flies, mosquitoes.... At the entrance to the barn, it is necessary to arrange disinfection pits, change labor protection for people entering and exiting livestock production areas; have isolated cages to raise newly imported pigs or raise sick pigs; have waste collection and treatment areas; if possible, rearing by the method of spacing, each barn has a space of 0.8-1m to minimize the pigs between the cages coming into contact with each other. Do not share livestock equipment between cages; Sewage drainage from the barn to the waste treatment area must be sealed. Wastewater from any barn drains separately from that cage. In suspicious cases such as dead or alive pigs, it is necessary to report to the veterinary agency because the characteristic of the epidemic is not to die the whole herd, but to die slowly; Follow preventive measures, clean livestock areas and at markets as usual.
