Contact with a wound on the hand and contact with blood on pork is generally not a good way to contract rabies. Pork from the regular market is quarantined and generally does not contain the rabies virus.
Rabies is not something that only dogs and cats can be infected with, almost all mammals can be infected with rabies. Pork in the regular market is often strictly quarantined and generally does not carry the rabies virus, so having a wound on the hand and coming into contact with the blood on the pork generally does not lead to rabies infection.
Rabies virus is mainly infected through broken wounds. If bitten or scratched by a dog or cat, regardless of whether the dog or cat has rabies, it needs to be cleaned immediately and actively injected with rabies vaccine.
It is recommended to stay away from unrestrained stray dogs and cats as much as possible to avoid being scratched or bitten.
