California Code, Food and Agricultural Code (Formerly Agricultural Code) - FAC § 15075

(a) Any lot of commercial feed for which a hold order or notice is issued shall be held by the person having control of the feed and shall not be disturbed or moved except under the specific directions of the secretary pending final disposition pursuant to this chapter. This restriction does not prevent the person having control of the feed from inspecting any feed so seized, nor from taking therefrom, in the presence of a person designated by the secretary, a reasonable sample for evidence.

(b) The movement, distribution, or sale of all or part of any lot, parcel, or package of commercial feed that has been quarantined by the secretary, unless the movement has the prior approval of the secretary, is a violation of this chapter.
