146.23—Terminology and classification; flocks and products.
Participating flocks which have met the respective requirements specified in this section may be designated by the following terms and the corresponding designs illustrated in § 146.9 of this part :
(a) U.S. H5/H7 Avian Influenza Monitored.
This program is intended to be the basis from which the table-egg layer industry may conduct a program to monitor for the H5/H7 subtypes of avian influenza. It is intended to determine the presence of the H5/H7 subtypes of avian influenza in table-egg layers through routine serological surveillance of each participating commercial table-egg layer flock. A flock will qualify for this classification when the Official State Agency determines that it has met one of the following requirements:
(1)
It is a commercial table-egg layer flock in which a minimum of 11 birds or egg samples have been tested negative for antibodies to the H5/H7 subtypes of avian influenza within 30 days prior to disposal;
(2)
It is a commercial table-egg layer flock in which a minimum of 11 birds or egg samples have been tested negative for antibodies to the H5/H7 subtypes of avian influenza within a 12-month period; or
(3)
It is a commercial table-egg layer flock that has an ongoing active and diagnostic surveillance program for the H5/H7 subtypes of avian influenza in which the number of birds or egg samples tested is equivalent to the number required in paragraph (a)(1) or (a)(2) and that is approved by the Official State Agency and the Service.
