General Quarantine Order; Influenza A Viruses in Ruminants; Exhibition of Dairy Cattle
[54 Pa.B. 7567]
[Saturday, November 23, 2024]Recitals:
The following recitals set forth and describe the dangerous transmissible disease for which this Quarantine Order is instituted, specify the species of domestic animals affected by and subject to this Quarantine Order, and provides the authority under which this Quarantine Order is established.
A. Influenza A viruses have the potential to mutate and transfer into different host species.
B. The Highly Pathogenic Avian Influenza (HPAI) Eurasian lineage goose/Guangdong H5 clade 2.3.4.4 virus has been confirmed in wild birds and in poultry flocks across the United States in 2024.
C. HPAI has caused substantial loss in the past to the Pennsylvania poultry industry and has caused widespread losses to the poultry industry in states in which poultry have been infected.
D. Certain influenza A viruses, including H5 and H7 viruses, can cause severe disease in poultry and other avian species and have also been identified as a cause of clinical disease in other animals, including dairy cattle and juvenile goats. In March 2024, an H5 influenza A virus was identified as a cause of a multistate outbreak of disease in dairy cattle. Clinical signs in dairy cattle include a decrease in feed consumption, with a simultaneous decrease in rumination and rumen motility; respiratory signs including clear nasal discharge; and subsequent acute drop in milk production. Additional clinical signs may include abnormal tacky or loose feces, lethargy, dehydration, and fever. Severely affected cattle may have thicker, concentrated, colostrum-like milk or produce no milk at all. The ability of the H5 influenza A virus to be transmitted between poultry and cattle poses a threat to both the poultry and the cattle industries in Pennsylvania by threatening the safety or quality of the food supply and the economic wellbeing of the domestic animal and allied industries. In addition, H5 and H7 influenza A viruses in ruminants may pose a risk to public health due to their zoonotic potential.
E. Section 2321(a) of the Domestic Animal Law (relating to specific dangerous transmissible diseases) (3 Pa.C.S. § 2321(a)) establishes specific transmissible diseases as dangerous transmissible diseases within the meaning of the Domestic Animal Law.
F. Section 2321(d) of the Domestic Animal Law (relating to designation of additional dangerous transmissible disease through temporary order) provides, ''Upon the determination that a transmissible disease not listed in subsection (a) and not designated a dangerous transmissible disease through regulation under subsection (b) presents a danger to public health, to domestic animal health, to the safety or quality of the food supply or to the economic wellbeing of the domestic animal industries, the department shall issue a temporary order proclaiming that transmissible disease to be a dangerous transmissible disease within the meaning of this chapter. . .'' (3 Pa.C.S. § 2321(d)).
G. The Department amended a previous Temporary Order Designating Dangerous Transmissible Diseases published in the Pennsylvania Bulletin on December 2, 2023 (53 Pa.B. 7373) to include ''Influenza A Viruses in Ruminants'' as a dangerous transmissible disease. The amended Temporary Order was published in the April 20, 2024, edition of the Pennsylvania Bulletin (54 Pa.B. 2098) and such designation was effective immediately upon publication of that edition.
H. Section 2329(a) of the Domestic Animal Law (relating to power to establish and enforce), authorizes the Department to establish a Quarantine Order ''Whenever a dangerous transmissible disease. . .exists anywhere within or outside of this Commonwealth, or whenever it is deemed advisable to test or treat any domestic animal upon the reasonable suspicion that it has contracted or been exposed to a dangerous transmissible disease. . .or whenever the testing or treatment of a domestic animal indicates that the domestic animal has been exposed to a dangerous transmissible disease. . .so as to render future accurate testing for recent exposure of that domestic animal to that dangerous transmissible disease. . .impractical or impossible, the department shall have the power to establish and enforce quarantines of any such infected, exposed, contaminated, suspected or susceptible domestic animal. In addition to the aforedescribed domestic animals, a quarantine may apply to any goods, products, facilities, containers, vehicles or materials that may carry dangerous transmissible disease. . .and may be applied on or in or against any premises, area or locality as defined in this chapter.'' (3 Pa.C.S. § 2329(a)).
I. Section 2329 (related to quarantine) of the Domestic Animal Law (3 Pa.C.S. § 2329) establishes three different types of quarantine orders—Interstate and International (3 Pa.C.S. § 2329(c)), General (3 Pa.C.S. § 2329(d)) and Special (3 Pa.C.S. § 2329(e))—the Department may impose.
J. Section 2329(d) of the Domestic Animal Law provides specific authority to establish and enforce a general quarantine order ''. . .against any area or locality within this Commonwealth for any of the reasons set forth in subsection (a) to prevent a dangerous transmissible disease. . .from being carried into, within, from or out of the area or locality that is subject to the quarantine. A general quarantine order may include any domestic animals, conveyances, containers, goods, products or materials that may carry dangerous transmissible disease. . .and may include any area or locality, including all buildings, structures, premises and equipment located therein.'' (3 Pa.C.S.A. § 2329(d)).
K. The Department has established a Lactating Dairy Cow Health Monitoring Program for Pennsylvania dairy producers, to promote influenza A surveillance of Pennsylvania dairy herds through weekly testing of a representative herd milk sample (bulk tank or in-line sample). Enrollment in this Pennsylvania program and compliance with the program standards provides Pennsylvania producers an alternative to testing individual animals prior to entry into a Pennsylvania exhibition.
