7 U.S.C. § 2622 (AGRICULTURE)
§ 2622. Investigations
(a) Administration of oath; subpena; contempts; process; jurisdiction
The Secretary may make such investigations as he deems necessary for the effective carrying out of his responsibilities under this chapter or to determine whether any person has engaged or is engaging in any acts or practices which constitute a violation of any provision of this chapter, or of any plan, or rule or regulation issued under this chapter. For the purpose of any such investigation, the Secretary is empowered to administer oaths and affirmations, subpena witnesses, compel their attendance, take evidence, and require the production of any books, papers, and documents which are relevant to the inquiry. Such attendance of witnesses and the production of any such records may be required from any place in the United States. In case of contumacy by, or refusal to obey a subpena issued to, any person, including a handler, the Secretary may invoke the aid of any court of the United States within the jurisdiction of which such investigation or proceeding is carried on, or where such person resides or carries on business, in requiring the attendance and testimony of witnesses and the production of books, papers, and documents; and such court may issue an order requiring such person to appear before the Secretary, there to produce records, if so ordered, or to give testimony touching the matter under investigation. Any failure to obey such order of the court may be punished by such court as contempt thereof. All process in any such case may be served in the judicial district whereof such person is an inhabitant or wherever he may be found. The site of any hearings held under this section shall be within the judicial district where such person is an inhabitant or has his principal place of business.
(b) Self-incrimination; privilege
No person shall be excused from attending and testifying or from producing books, papers, and documents before the Secretary, or in obedience to the subpena of the Secretary, or in any cause or proceeding, criminal or otherwise, based upon, or growing out of any alleged violation of this chapter, or of any plan, or rule or regulation issued thereunder on the ground or for the reason that the testimony or evidence, documentary or otherwise, required of him may tend to incriminate him or subject him to a penalty or forfeiture; but no individual shall be prosecuted or subjected to any penalty or forfeiture for or on account of any transaction, matter, or thing concerning which he is compelled, after having claimed his privilege against self-incrimination, to testify or produce evidence, documentary or otherwise, except that any individual so testifying shall not be exempt from prosecution and punishment for perjury committed in so testifying.
