What is required for the movement of swine into California?

The movement of swine into California requires a health certificate within 30 days. This health certificate ensures that the animals are inspected and found to be free from contagious diseases, complying with the state's veterinary regulations. It also provides documentation that the animals have received appropriate vaccinations and that they come from a facility that adheres to health standards. This requirement is crucial for preventing the introduction and spread of diseases within the state, protecting local livestock and the swine industry. Proper documentation not only serves the purpose of biosecurity but also facilitates traceability in case of disease outbreaks.

The other options may be relevant in broader contexts of livestock management or specific scenarios but do not fulfill the mandatory documentation requirement for moving swine into California. Therefore, having a current health certificate is the primary requirement that ensures the health and safety of swine entering the state.
