Sick pigs can't eat meat. Sick pigs carry various pathogens, such as parasites, bacteria and viruses. These pathogens will be ingested into human body with pork, leading to human infection diseases, such as food poisoning, liver injury, parasitic infection, virus and bacterial infection. Sick pigs are often ill and in sub-health state, and their meat quality will also be affected, and their taste and quality will be reduced, making them unfit for eating.
