Business-centric data solutions for safeguarding animal agriculture in the United States of America.

Business-centric solutions to data-related problems often yield the greatest positive impacts and improvements for private enterprises but are challenging to design and implement at scale within government agencies. The core mission of the Veterinary Services of the United States Department of Agriculture (USDA) Animal Plant Health Inspection Service is to safeguard animal agriculture in the United States of America, and effective data management underpins these efforts. As this agency works to assist data-driven decision-making in animal health management, it continues to use a blend of best practices from Federal Data Strategy initiatives and the International Data Management Association framework. This paper describes three case studies that focus on strategies to improve animal health data collection, integration, reporting and governance for animal health authorities. These strategies have enhanced the way USDA's Veterinary Services execute their mission and core operational activities for prevention, detection and early response to support disease containment and control.

S'agissant des problèmes en lien avec les données, les solutions centrées sur l'activité sont souvent celles qui génèrent le plus d'effets positifs et d'améliorations pour les entreprises du secteur privé, mais elles sont difficiles à concevoir et à mettre en oeuvre à grande échelle au sein des agences gouvernementales. Les Services vétérinaires du Service d'inspection de la santé animale et végétale du département américain de l'Agriculture (USDA) ont pour mission centrale de préserver les productions animales états-uniennes ; une gestion efficace des données vient soutenir cet effort. Dans leur action d'appui aux processus décisionnels de gestion de la santé animale fondés sur les données, ces Services recourent à une combinaison de bonnes pratiques mises en oeuvre aussi bien par les initiatives de la Stratégie fédérale sur les données que dans le cadre de l'Association internationale de gestion des données. Les auteurs décrivent trois études de cas sur des stratégies visant à améliorer la collecte, l'intégration, la notification et la gouvernance des données de santé animale afin de répondre aux besoins des autorités compétentes dans ce domaine. Ces stratégies ont permis aux Services vétérinaires de l'USDA de mieux s'acquitter de leur mission et d'améliorer leurs activités opérationnelles de prévention, de détection et de réaction rapide afin d'endiguer et contrôler les maladies.

Las soluciones eminentemente empresariales a problemas relacionados con los datos deparan con frecuencia los mejores frutos y resultados a la empresa privada, pero son difíciles de diseñar y aplicar a escala dentro de las administraciones públicas. Los Servicios Veterinarios adscritos al Servicio de Inspección Sanitaria de Animales y Plantas del Departamento de Agricultura de los Estados Unidos (USDA) tienen por principal cometido salvaguardar la producción animal estadounidense, labor que pasa en parte por una eficaz gestión de los datos. En su función de apoyo a la adopción de decisiones de gestión zoosanitaria basadas en los datos, este organismo sigue empleando una combinación de prácticas óptimas tomadas de iniciativas de la Estrategia Federal de Datos y de las pautas marcadas por la Asociación Internacional de Gestión de Datos. Los autores presentan y analizan tres ejemplos de estrategias para mejorar la obtención, integración, notificación y administración de datos zoosanitarios para las autoridades del ramo. Estas estrategias han conferido mayor eficacia a los Servicios Veterinarios del USDA en el cumplimiento de su misión y en la ejecución de sus principales actividades operativas de prevención, detección y pronta respuesta para ayudar a contener y combatir enfermedades.

Risk factors associated with clinical signs of vesicular stomatitis and seroconversion without clinical disease in Colorado horses during the 2014 outbreak.

Vesicular stomatitis (VS) is caused by a contagious rhabdovirus that affects horses, cattle, and swine. Clinical signs of vesicular stomatitis virus (VSV) infection in pigs and cattle are indistinguishable from foot-and-mouth disease (FMD), a foreign animal disease and reportable disease in the United States (Rodriguez et al., 2000). A VS epidemic occurred in the Rocky Mountain region in 2014-15. A study was conducted in Colorado to evaluate horse- and management-level factors associated with VS. For a horse to be considered a clinical VS horse, there were two requirements. First, clinical VS horses had to have clinical signs consistent with VS, including one or more of the following: vesicles, ulcers, erosions or crusting on the muzzle, nares, lips, oral or nasal mucosa, ears, ventrum, udder or penile sheath, or coronary band lesions. Second, clinical VS horses had to have laboratory confirmation of VSV exposure via virus isolation from lesions or a positive complement fixation test performed on sera. All non-clinical horses residing on VSV-affected premises enrolled in the study were evaluated for exposure (i.e., seroconversion) to VSV. Overall, management and housing data were collected from 334 horses on 48 premises in Colorado. Approximately one-third (31.4%) of enrolled horses were clinical cases and two-thirds (68.6%) were controls. Three premises-matched logistic regression models were constructed in SAS using backward elimination (P-value < 0.05) after univariate screening of a priori-selected variables (P-value < 0.20). Model outcomes included differences in characteristics and management of 1) clinical and nonclinical horses, 2) exposed and unexposed horses, and 3) exposed nonclinical and unexposed nonclinical horses. Overall, factors most strongly associated with risk of being a VS clinical horse were access to pasture (P-value = 0.002), and pregnancy status (P-value = 0.001). Factors most strongly associated with VSV exposure among horses were access to pasture (P-value = 0.003) and lack of any insect control (P-value = 0.001). The only factor associated with VSV-exposed nonclinical horses compared with unexposed VSV horses was contact with clinical horses (P-value = 0.013). There were no associations identified regarding clinical horses compared with exposed nonclinical horses. With regard to severity of lesions (severe vs. moderate or mild), no variables met the criteria for inclusion in the multivariable model. Results of this study provide evidence that pasture access and fly control are important factors associated with VSV exposure.

Case-control study of a multistate equine herpesvirus myeloencephalopathy outbreak.

BACKGROUND: A large multistate outbreak of equine herpesvirus myeloencephalopathy (EHM) occurred in May 2011 among horses that participated in a competitive event. OBJECTIVE: To identify EHM risk factors among horses with a common exposure venue. ANIMALS: A total of 123 horses: 19 horses with EHM, 14 equine herpesvirus-1 cases with no reported neurologic signs, and 90 control horses. METHODS: EHM case survey data were compared with data from EHV-1 cases with no neurologic signs and healthy controls using univariable and multivariable methods. RESULTS: Significant factors associated with higher risk for EHM compared with EHV-1 cases with no neurologic signs were (1) greater number of biosecurity risks at the event, (2) female sex, (3) increasing number of classes competed in at the event, and (4) an interaction between sex and number of classes competed in. In the EHM versus controls comparison, in addition to sex and biosecurity risks, factors associated with higher EHM risk included EHV-1 vaccination in the 5 weeks before the event and increasing number of events attended in April 2011; zinc dietary supplementation was associated with decreased risk. An interaction between sex and the number of events attended in April 2011 also was significant. CONCLUSIONS AND CLINICAL IMPORTANCE: Findings from this study suggest that dietary zinc supplementation may be associated with decreased risk of EHM. Several factors were associated with increased risk of EHM. Additional investigations of factors associated with risk of EHM are warranted to evaluate the importance of these factors in this complex disease of horses.
