§ 145.103 Terminology and classification; flocks and products. Participating flocks, and the eggs, chicks, started, and mature birds produced from them, which have met the respective requirements specified in this section may be designated by the following terms and the corresponding designs illustrated in § 145.10. ( a ) [Reserved]
( b ) *U.S. Pullorum-Typhoid Clean.* A flock in which freedom from pullorum and typhoid has been demonstrated to the Official State Agency under paragraph (b)(1), (2), or (3) of this section. (See § 145.14 relating to the official blood test where applicable.): ( 1 ) It has been officially blood tested within the past 12 months with either no reactors or reactors that, upon further bacteriological examination conducted in accordance with part 147 of this subchapter, fail to isolate *S. pullorum* or *S. gallinarum.*
( 2 ) It is a started or mature bird flock that meets the following specifications as determined by the Official State Agency and the Service: ( i ) The flock is located in a State where all persons performing poultry disease diagnostic services within the State are required to report to the Official State Agency within 48 hours the source of all poultry specimens from which *S. pullorum* or *S. gallinarum* is isolated;
( ii ) The flock is composed entirely of birds that originated from U.S. Pullorum-Typhoid Clean breeding flocks or from flocks that met equivalent requirements under official supervision; and
( iii ) The flock is located on a premises where a flock not classified as U.S. Pullorum-Typhoid Clean was located the previous year; *Provided,* That an Authorized Testing Agent must blood test up to 300 birds per flock, as described in § 145.14, if the Official State Agency determines that the flock has been exposed to pullorum-typhoid. In making determinations of exposure and setting the number of birds to be blood tested, the Official State Agency shall evaluate the results of any blood tests, described in § 145.14(a)(1), that were performed on an unclassified flock located on the premises during the previous year; the origins of the unclassified flock; and the probability of contacts between the flock for which qualification is being sought and infected wild birds, contact between the flock for which qualification is being sought and contaminated feed or waste, or contact between the flock for which qualification is being sought and birds, equipment, supplies, or personnel from flocks infected with pullorum-typhoid.
( 3 ) It is a breeding flock that originated from U.S. Pullorum-Typhoid Clean breeding flocks or from flocks that met equivalent requirements under official supervision, and in which a sample of 300 birds from flocks of more than 300, and each bird in flocks of 300 or less, has been officially tested for pullorum-typhoid with no reactors or reactors that upon bacteriologic examination fail to reveal Pullorum-Typhid: *Provided,* That a bacteriological examination monitoring program or serological examination monitoring program for game birds acceptable to the Official State Agency and approved by the Service may be used in lieu of annual blood testing: *And provided further,* That it is located in a State in which it has been determined by the Service that: ( i ) All hatcheries within the State are qualified as “National Plan Hatcheries” or have met equivalent requirements for pullorum-typhoid control under official supervision;
( ii ) All hatchery supply flocks within the State are qualified as U.S. Pullorum-Typhoid Clean or have met equivalent requirements for pullorum-typhoid control under official supervision: *Provided,* That if other domesticated fowl, except waterfowl, are maintained on the same premises as the participating flock, freedom from pullorum-typhoid infection shall be demonstrated by an official blood test of each of these fowl;
( iii ) All shipments of products other than U.S. Pullorum-Typhoid Clean, or equivalent, into the State are prohibited;
( iv ) All persons performing poultry disease diagnostic services within the State are required to report to the Official State Agency within 48 hours the source of all poultry specimens from which *S. pullorum* or *S. gallinarum* is isolated;
( v ) All reports of any disease outbreak involving a disease covered under the Plan are promptly followed by an investigation by the Official State Agency to determine the origin of the infection; *Provided,* That if the origin of the infection involves another State, or if there is exposure to poultry in another State from the infected flock, then the National Poultry Improvement Plan will conduct an investigation;
( vi ) All flocks found to be infected with pullorum or typhoid are quarantined until marketed or destroyed under the supervision of the Official State Agency, or until subsequently blood tested, following the procedure for reacting flocks as contained in § 145.14(a)(5), and all birds fail to demonstrate pullorum or typhoid infection;
( vii ) All poultry, including exhibition, exotic, and game birds, but excluding waterfowl, going to public exhibition shall come from U.S. Pullorum-Typhoid Clean or equivalent flocks, or have had a negative pullorum-typhoid test within 90 days of going to public exhibition; and
( viii ) The flock is located in a State in which pullorum disease or fowl typhoid is not known to exist nor to have existed in hatchery supply flocks within the State during the preceding 24 months.
( ix ) Discontinuation of any of the conditions or procedures described in paragraphs (b)(3)(i) through (viii) of this section, or the occurrence of repeated outbreaks of pullorum or typhoid in poultry breeding flocks within or originating within the State shall be grounds for the Service to revoke its determination that such conditions and procedures have been met or complied with. Such action shall not be taken until a thorough investigation has been made by the Service and the Official State Agency has been given an opportunity to present its views.
( c ) *U.S. H5/H7 Avian Influenza Clean.* The program in this paragraph (c) is intended to be the basis from which the game bird industry may conduct a program for the prevention and control of the H5 and H7 subtypes of avian influenza. It is intended to determine the presence of the H5 and H7 subtypes of avian influenza in game bird flocks through routine surveillance of each participating flock. A flock or premises, and the hatching eggs, chicks, started, and mature birds produced from it, will qualify for the classification in this paragraph (c) when the Official State Agency determines that it has met the following requirements: ( 1 ) It is a flock in which a minimum of 30 birds has been tested negative to the H5 and H7 subtypes of avian influenza as provided in § 145.14(d) when more than 4 months of age. To retain the classification in this paragraph (c): ( i ) A sample of at least 30 birds must be tested negative at intervals of 90 days; or
( ii ) A sample of fewer than 30 birds may be tested, and found to be negative, at any one time if all pens are equally represented and a total of 30 birds are tested within each 90-day period.
( 2 ) For participants with non-breeding flocks retained for raised-for-release or other purposes on the same premises as a breeding flock, a representative sample of at least 30 birds from the participating premises must be tested negative to the H5 and H7 subtypes of avian influenza as provided in § 145.14(d) when more than 4 months of age, every 90 days.
( d ) *U.S. Salmonella Monitored.* The program in this paragraph (d) is intended to be the basis from which the game bird industry may conduct a program for the prevention and control of salmonellosis. It is intended to reduce the incidence of *Salmonella* organisms in day-old poultry through an effective and practical sanitation program in the hatchery. This will afford other segments of the poultry industry an opportunity to reduce the incidence of *Salmonella* in their products. The following requirements must be met for a flock to be of this classification in this paragraph (d): ( 1 ) An Authorized Agent shall collect a minimum of five environmental samples, *e.g.,* chick papers, hatching trays, and chick transfer devices, from the hatchery at least every 30 days. Testing must be performed at an authorized laboratory.
( 2 ) To claim products are of the classification in this paragraph (d), all products shall be derived from a hatchery that meets the requirements of the classification.
( 3 ) The classification in this paragraph (d) may be revoked by the Official State Agency if the participant fails to follow recommended corrective measures.
