After being accredited in state A, a veterinarian establishing a practice in state B must issue health certificates only if they are:

• A. Be licensed and accredited by state B
• B. Practice in state B for one year
• C. Do nothing since accreditation is accepted in all states
• D. Write the state board in state B

Answer: (A)

Health certificates are official acts that must be issued by a veterinarian who has the authority to practice in the state where the animals are located. Accreditation in one state does not automatically grant that authority in another state. When establishing a practice in state B, a veterinarian needs to be licensed to practice in state B and hold the state's required accreditation to legally sign and issue health certificates there. This ensures the certificate is valid and endorsed by the state’s animal-health authority. The other options fail because one year of practice doesn’t confer the right to issue certificates, accreditation in another state isn’t automatically accepted, and simply writing the state board doesn’t authorize issuance without the proper state licensure and accreditation.
