What do you think of slaughter and quarantine as a dead pig or a sick pig?

After the dead pig was slaughtered, there was almost no blood in the meat and internal organs. Sick pigs often have injections and liquid medicine is injected into their necks, that is, in some places, the meat turns black or other colors are necrotic, and some diseased skins will also change. For example, the skin of erysipelas and typhoid bacilli will be congested and discolored.
