(1) before the state veterinarian or board, or in obedience to a subpoena of the state veterinarian or board, regardless of whether the subpoena was signed or issued by the state veterinarian, the state veterinarian delegate, or board; or
(2) in a cause or proceeding, criminal or civil, based upon or growing out of an alleged violation of this chapter;
on the ground that the testimony, evidence, documents, or other evidence required of the person may tend to incriminate the person or subject the person to a penalty or forfeiture.
(b) A person may not be prosecuted or subjected to a penalty or forfeiture for or on account of a transaction, matter, or thing concerning which the person is compelled to testify or produce testimony, evidence, documents, or other evidence after having claimed the person's privilege against self-incrimination. However, a person testifying is not exempt from prosecution and punishment for perjury.
