Cal. Food & Agric. Code § 55702

(a) Except as otherwise provided in this section, any person who sells or furnishes livestock to a meatpacker, shall have a lien, not dependent upon possession, on the livestock and upon the identifiable proceeds and products thereof, for the unpaid part of the purchase price, or for the unpaid value of the livestock at the time of the transfer of possession if no purchase price has been agreed upon. The lien shall commence on the date of the transfer of possession of the livestock to the meatpacker and shall have priority over all other liens upon, and security interests in, the livestock and the identifiable proceeds and products thereof, without regard to the time of attachment or perfection of such other liens or security interests and shall remain a lien upon the livestock and the identifiable proceeds and products thereof notwithstanding sale, exchange, or other disposition thereof.
(b) Notwithstanding the provisions of subdivision (a), a buyer in the ordinary course of business, as that term is defined in paragraph (9) of subdivision (b) of Section 1201 of the Commercial Code, shall take free of such lien even though the buyer knows of the existence of the lien.
(c) Notwithstanding the provisions of subdivision (a), the lien shall cease to be of any force or effect after the expiration of 21 days from the date of delivery of the livestock unless a notice of lien is filed pursuant to subdivision (e), in which case the lien shall remain effective as long as such notice shall remain effective.
(d) No person shall have a lien pursuant to subdivision (a) to the extent that the person shall have made the livestock available to the meatpacker on credit terms.
(e) Any person selling or delivering livestock who claims a lien under this article shall file a statement with the Secretary of State and a copy thereof with the director, both within 21 days after delivery of the livestock to the meatpacker.
