7 Pa. Code § 1.575
No article or livestock retained in accordance with this Subchapter shall be moved by any person from the place at which it is located when so retained until released by an authorized representative of the Department. However, any such article or livestock may be moved from the place at which it is located when so detained for refrigeration, freezing or storage purposes if such movement has been approved by an authorized representative of the Department and the article or livestock so moved shall be retained by an authorized representative of the Department after movement until such time as the retention is terminated. When the retention of such article or livestock is terminated, the owner or his agent or the carrier or other person in possession of the article or livestock who was notified when the article or livestock was retained will receive notification of the termination. The notification shall be served by either delivering the notice to such person at his last known residence or principal office or place of business. All official marks may be required by such representative to be removed from the article or livestock before it is released unless it appears to the satisfaction of the representative that the article or livestock is eligible to retain such marks.
