(a) Quarantine provisions.
  (1) Poultry and/or premises shall be placed under quarantine when evidence of infection or possible exposure to any contagious and/or communicable disease not considered to be endemic exists in the State of Texas. A quarantine shall remain in effect until epidemiological evidence of the existing disease or exposure thereto is satisfied. After due consideration of epidemiological evidence, the executive director of the commission may cause the quarantine to be released.
  (2) When Laryngotracheitis infection is confirmed in any house on a farm, the entire farm will be placed under quarantine, and all poultry on that farm will be considered infected and no molting will be allowed until after the quarantine has been released. Official quarantine signs will be posted in a prominent place at the entrance to the premise and on the doors of each house. The doors should be locked when the house is unattended.
  (3) Premises may be released from a Laryngotracheitis quarantine when:
    (A) the farm has been depopulated and established cleaning and disinfection procedures have been applied;
    (B) all infected poultry have been removed and all replacement poultry have been vaccinated twice with cell culture vaccine, no chick embryo origin vaccine has been used, and a surveillance system as established by the commission is carried out with no evidence of active infection; or
    (C) all dead poultry and caked litter are removed; the houses are sprayed with disinfectant and closed for 15 to 30 days; and two consecutive sets of nonvaccinated poultry are raised in the houses with no evidence of infection based on commission surveillance.
  (4) When fowl typhoid (S. gallinarum) infection is confirmed in a flock, the farm on which the flock is located shall be placed under quarantine and the flock depopulated. Following depopulation and burial or incineration of all poultry, nest material, and litter, the premise and facilities shall be cleaned and disinfected. The premise shall remain quarantined for at least 180 days following depopulation during which time poultry shall not be reintroduced to the premises. Following removal of the quarantine, repopulation of the premises may be allowed with poultry that have been tested negative to fowl typhoid.
(b) Public exhibitions. Poultry entered in public exhibition shall originate from flocks or hatcheries free of pullorum disease and fowl typhoid or have a negative pullorum-typhoid test within 30 days before exhibition. Chickens or turkeys entered in public exhibition shall be accompanied by a certificate of source.
(c) Public sales. Poultry offered for public sale or trade at markets such as trade days, flea markets, auctions, or any other public sale shall originate from pullorum-typhoid clean flocks or hatcheries. The seller shall furnish proof of the source of poultry or hatching eggs offered for public sale. The owner or management of any market or public sale shall prevent the sale, trade, or offer for sale of any poultry that is not properly qualified under the Texas Pullorum-Typhoid Program as prescribed by the Texas Veterinary Medical Diagnostic Laboratory (TVMDL) and/or the National Poultry Improvement Plan. Failure to enforce this requirement may result in the seeking of a court order prohibiting any further sale of poultry on the grounds. Poultry from states other than Texas shall be accompanied by a health certificate from the state of origin, including a negative pullorum-typhoid test within 30 days of the sale as described in subsection (e)(1) of this section. Poultry not properly identified and qualified as pullorum-typhoid clean are prohibited from sale and shall be returned to the owner's or dealer's premises.
(d) Surveillance. The commission may pick up dead poultry at farms to determine if Laryngotracheitis or any other disease is present in any area.
(e) Interstate Movement.
  (1) Poultry shipped into the State of Texas shall be accompanied by an official health certificate issued by an accredited veterinarian within 30 days prior to shipment. The health certificate shall state that the poultry have been inspected and are free of evidence of infectious or contagious disease; that the poultry have been vaccinated only with approved vaccines as defined in this regulation; and that the poultry have not originated from an area that has had active Laryngotracheitis or chicken embryo origin Laryngotracheitis vaccine virus within the last 30 days. The certificate shall also state the poultry have passed a negative test for pullorum-typhoid within 30 days prior to shipment or that they originate from flocks which have met the pullorum-typhoid requirements of the Texas Pullorum-Typhoid Program and/or the National Poultry Improvement Plan. Baby poultry will be exempt from this section if from an NPIP, or equivalent, hatchery, and accompanied by NPIP Form 9-3, or APHIS Form 17-6; or, are covered by an approved "Commuter Poultry Flock Agreement" on file with the state of origin and the commission.
  (2) An official health certificate is not required on poultry consigned to slaughter establishments, which maintain federal postmortem inspection, provided the shipment is accompanied by a waybill indicating the plant of destination.
  (3) Live poultry, unprocessed poultry, hatching eggs, unprocessed eggs, egg flats, poultry coops, cages, crates, other birds, and used poultry equipment affected with, or recently exposed to, infectious, contagious, or communicable disease, or originating in state or federal quarantined areas shall not enter Texas without express written consent from the commission.
(f) Depopulation and disposition of poultry and eggs. The commission shall depopulate or dispose of poultry and/or hatching eggs that pose a threat to the poultry industry of the State of Texas after a hearing before the commission pursuant to the Administrative Procedure Act.
(g) Dead poultry disposal. Dead poultry are to be disposed of by incinerating, burying in disposal pits, or hauling to a rendering plant in closed containers.
(h) Cleaning and disinfecting.
  (1) Premises found to have housed, incubated, brooded, or ranged an infected flock shall be cleaned and disinfected under the supervision of the commission within 15 days following depopulation, unless an extension of time is granted. Infected premises shall not be restocked with poultry or eggs for hatching purposes until the cleaning and disinfecting requirement of this subsection is certified complete by the commission. The following cleaning and disinfection procedures are approved for Laryngotracheitis:
    (A) completely clean house, spray with disinfectant, and close for 15-30 days; or
    (B) remove all dead poultry and caked litter, spray with disinfectant, and close for 15-30 days.
  (2) Trucks, loading equipment, cages, or coops used in hauling poultry vaccinated with restricted vaccines or infected with a reportable disease within a designated area or from a designated area shall be cleaned and disinfected prior to entering premises on which the disease has not been diagnosed and the vaccine has not been used or as directed by the commission.
(i) Designated area for Laryngotracheitis. The following procedures shall apply to all poultry operations:
  (1) Replacement poultry. All poultry housed in the designated area will be vaccinated twice (no earlier than four weeks of age and again at least four weeks later) with cell culture (eye drop) modified vaccine before being housed for egg production. A certificate of vaccination must be on file with the owner, farm manager, and the commission. Prior entry permit and health certificate with vaccination history are required for poultry originating out-of-state. These poultry may receive the second vaccination upon arrival at farm, but the first vaccination must be no earlier than four weeks of age.
  (2) Molted hens.
    (A) Any hen molted and retained for egg production must be vaccinated with cell culture vaccine after molting.
