A. The provisions of the preceding section shall not apply to weed-infested material in storage in, or consigned to, a processing establishment for cleaning or processing, or weed-infested material transported by producers from their farms to an elevator, or from farm-to-market. Any labeling, invoice, or other representation which may be made with respect to the uncleaned or unprocessed weed-infested material shall be subject to the provisions of this subarticle.

B. No unprocessed weed-infested material shall be transported by any person over or along any road or highway in this state or by any railroad operating in this state, unless the same is carried or transported in a vehicle or containers adequate to prevent the leaking or scattering of the weed-infested material. In no instance shall weed-infested material be sold to the ultimate consumer (including a livestock feeder) until the material shall have been processed to destroy the viability of the noxious weed-infested content.
