What is the quarantine period for a pig that has bitten a person?

The correct quarantine period for a pig that has bitten a person is indeed 30 days. This time frame is established as a standard practice to monitor the animal for signs of rabies or other illnesses that could pose a risk to human health. During this 30-day period, the pig is observed for any behavioral changes or symptoms indicative of disease, ensuring that if the animal is carrying any pathogens, they can be identified and managed before they pose a risk to humans. This practice is crucial, as rabies is a serious disease that can be transmitted through bites, and proper quarantine helps in safeguarding both public health and animal welfare.

Other options, while they may reflect different periods of observation or action for other species or situations, do not align with the established protocol for pigs specifically involved in bite incidents.
