Extending Knowledge On Biosecurity In Small-Scale And Backyard Systems In The United States, Juliette Di Francesco, Amber Itle, Craig Mcconnel, Ragan Adams, Roselle Busch, Richard Van Vleck Pereira, Terry W. Lehenbauer, Beatriz Martínez-López, Alda F. A. Pires

The Journal of Extension

The number of small-scale and backyard operations has increased in the United States during the past decade, but there is currently a lack of outreach efforts and readily-available educational materials targeting these farming systems. We developed a webinar series on biosecurity to provide training for small-scale and backyard producers, and training tools that can be used by local veterinarians and extension educators to disseminate knowledge and consistent recommendations more effectively. Fewer people attended the webinars than registered, suggesting a gap between interest in biosecurity and commitment to the topic. Participants in the webinar series reported a high level of satisfaction …

Introduction: The 2022–2023 highly pathogenic avian influenza (HPAI) H5N1 outbreak in the United States (U.S.) is the most geographically extensive and costly animal health event in U.S. history. In 2022 alone, over 57 million commercial and backyard poultry in 47 U.S. states were affected. Over 75% of affected poultry were part of the commercial table egg production sector. Methods: We conducted a case–control study to identify potential risk factors for introduction of HPAI virus onto commercial table egg operations. Univariate and multivariable analyses were conducted to compare farm characteristics, management, and biosecurity factors on case and control farms. Results: Factors …

Wild Dogs And Decolonization: Ivan Sen’S Mystery Road And Omar Musa’S Here Come The Dogs, Iris Ralph

Animal Studies Journal

The broad subject of First Nations and decolonial perspectives on animal flourishing is addressed in this paper in a reading of references to canids in Mystery Road (2013), a film by the First Nations-Australian director, Ivan Sen, and Here Come the Dogs (2014), a novel by the Malaysian-Australian author Omar Musa. Dingoes and other wild dogs are a prominent trope in Sen’s film and tie to seemingly perdurable debates about the rights of these animals to flourish in Australia. Dingo advocates argue that dingoes are endemic to Australia, are Australia’s oldest introduced animals, and are a top predator species and …

Effects Of Social Cues On Biosecurity Compliance In Livestock Facilities: Evidence From Experimental Simulations, Luke Trinity, Scott C. Merrill, Eric M. Clark, Christopher J. Koliba, Asim Zia, Gabriela Bucini, Julia M. Smith

College of Agriculture and Life Sciences Faculty Publications

Disease outbreaks in U.S. animal livestock industries have economic impacts measured in hundreds of millions of dollars per year. Biosecurity, or procedures intended to protect animals against disease, is known to be effective at reducing infection risk at facilities. Yet, to the detriment of animal health, humans do not always follow biosecurity protocols. Human behavioral factors have been shown to influence willingness to follow biosecurity protocols. Here we show how social cues may affect cooperation with a biosecurity practice. Participants were immersed in a simulated swine production facility through a graphical user interface and prompted to make a decision that …

Cattle Egrets Regurgitate House Mouse Carcasses Onto A Mouse-Free Island: Implications For Rodent Eradications, Aaron B. Shiels, Mele Khalsa, Doreen L. Griffin, Clay K. Chow, Sheri S. Mann, Antoinette J. Piaggio

USDA Wildlife Services: Staff Publications

Context. Eradication of invasive rodents on islands typically results in positive conservation gains, and maintaining a rodent-free island requires elevated biosecurity, including prevention of assisted rodent arrival via watercraft, aircraft and animals such as birds. Cattle egrets (Bubulcus ibis) are widespread, and often fly several kilometres daily to roost and forage. They frequently swallow insects and vertebrates (including rodents) whole, and some regurgitate prey. Cattle egrets have been regularly observed flying between the Hawaiian Islands of Ni’ihau (where non-native mice and rats are established) and Lehua (where one species of non-native rat is established and was targeted during …

Biosecurity Levels Of Livestock Enterprises In Turkey And Factors Affecting These Levels, Mehmet Feri̇t Can, Nuri̇ Altuğ, Ferhan Kaygisiz

Turkish Journal of Veterinary & Animal Sciences

Biosecurity (BS) is a multidimensional preventive medicine approach that has health, technical, and financial aspects. The purpose of this study was to determine the differences of the BS scores belonging to the livestock enterprises depending on the geographical region and breeding types and to predict the socioeconomic factors having an impact over the BS level. The study was conducted with 517 breeders who live in 7 different regions of Turkey. The results have revealed that the enterprises performing "beef cattle fattening and dairy cattle breeding together" have higher BS scores than the enterprises in the other breeding category (P < 0.01). The differences between the technical and financial scores according to geographical regions were statistically significant (P < 0.01). The regions categorized as "wes" have the highest score and "south" have the lowest score. It was determined that as the "educational level of the breeder" and "enterprise scale" increased, the BS score significantly went up. The regression model was found significant as a whole (P < 0.01) and the independent variables explained the variation in the technical and financial BS scores to be 14.6% and 12.7%, respectively. Dissemination of education/training practices and increasing enterprise scales will positively affect the level of BS in the sector.

Using Dna To Identify The Source Of Invasive Mongooses, Herpestes Auropunctatus (Carnivora: Herpestidae) Captured On Kaua‘I, Hawaiian Islands, Darren J. Wostenberg, Matthew W. Hopken, Aaron B. Shiels, Antoinette J. Piaggio

USDA Wildlife Services: Staff Publications

Two small Indian mongooses (Herpestes auropunctatus) were live-captured in 2012 at separate locations on the Hawaiian Island of Kaua'i, which was previously considered to be free of this invasive species. Genotypes from these two individuals were compared to genotypes of H. auropunctatus from the islands of Hawai'i (n =39), O'ahu (n =91), Maui (n = 39), and Moloka'i (n = 19) to determine the island of origin of the Kaua'i individuals. Genotypes were generated from each individual using five microsatellite loci. Genetic clustering was estimated by Bayesian inference of spatial clustering of individuals and …

Risk Attitudes Affect Livestock Biosecurity Decisions With Ramifications For Disease Control In A Simulated Production System, Gabriela Bucini, Scott C. Merrill, Eric Clark, Susan M. Moegenburg, Asim Zia, Christopher J. Koliba, Serge Wiltshire, Luke Trinity, Julia M. Smith

College of Agriculture and Life Sciences Faculty Publications

HOG producers' operational decisions can be informed by an awareness of risks associated with emergent and endemic diseases. Outbreaks of porcine epidemic diarrhea virus (PEDv) have been re-occurring every year since the first onset in 2013 with substantial losses across the hog production supply chain. Interestingly, a decreasing trend in PEDv incidence is visible. We assert that changes in human behaviors may underlie this trend. Disease prevention using biosecurity practices is used to minimize risk of infection but its efficacy is conditional on human behavior and risk attitude. Standard epidemiological models bring important insights into disease dynamics but have limited …

Reflecting Back On The Ebola Outbreak And The Future Of Bioterrorism, Christian Pedersen

Pepperdine Policy Review

In the wake of the 2014 Ebola outbreak, policy makers have focused on the public health components which led to the outbreak, the efforts to control it, and mitigate the impact of the outbreak. Some of the most enlightening aspects of the outbreak, pertain to National Security. The crisis demonstrated some crucial challenges the United States would have to plan for to effectively respond to a bioterrorist attack.

La Souffrance Animale À Distance: Des Vétérinaires Dans L’Action Humanitaire, Frédéric Keck, Miriam Ticktin

Publications and Research

Résumé

Cet article étudie le rôle des vétérinaires dans l’humanitaire à partir de deux types de pratique : la défense des animaux contre la cruauté et la surveillance des animaux touchés par les épidémies. En suivant l’extension de l’action humanitaire aux animaux comme nouvelles figures de victimes innocentes, nous cherchons à dépasser l’approche compassionnelle de l’humanitaire pour étudier les nouvelles formes scientifiques impliquant des non-humains, comme la médecine vétérinaire légale, les neurosciences et l’immunologie. Nous soutenons finalement que ces sciences produisent de nouveaux collectifs d’humains et de non-humains.

The President’S National Security Agenda Curtailing Ebola, Safeguarding The Future, Lawrence O. Gostin, Henry A. Waxman, William Foege

Georgetown Law Faculty Publications and Other Works

A clear lesson of the Ebola epidemic in West Africa is the need for strong public health systems globally, including in the United States. Ebola has highlighted the dangers of weak public health systems, from the immense shortage of health workers in West Africa to the budget cuts at the U.S. Centers for Disease Control and Prevention. In response to Ebola and the broader threat of infectious disease, President Obama has proposed a $6.2 billion supplemental funding request to Congress. The supplemental would surge resources for containing and treating Ebola in West Africa -- including a reserve of funds to …

The Global Health Security Agenda In An Age Of Biosecurity, Lawrence O. Gostin, Alexandra Phelan

Georgetown Law Faculty Publications and Other Works

Historically, the Oval Office has been a leader in global health assistance. From the President’s Emergency Plan for AIDS Relief (PEPFAR) and the President’s Malaria Initiative (PMI) under the Bush Administration, to the Global Health Initiative launched by President Obama in 2009. However, unlike PEPFAR and PMI, the Global Health Initiative met an untimely end with the launch of a bold new global health measure by the Obama Administration: the Global Health Security Agenda (GHS Agenda). The GHS Agenda aims to “accelerate progress toward a world safe and secure from infectious disease threats” through a US-led diplomatic collaboration with 30 …

Book Chapters

This chapter explores ethics, education and the life sciences in China. It is based on work conducted by the authors in two separate but complimentary projects. Barr’s observations derive from interviews and discussions in Beijing, Shanghai and Guangzhou with life scientists and policymakers in infectious-disease hospitals, university-research labs, the Chinese Academy of Sciences, and the Ministry of Health. Zhang’s study focused on China’s governance of stem-cell research and involved interviews with scientists, ethicists and policymakers at more than 25 sites across China. Below, we set the context by describing the role of science in China’s quest to become a leading …

Modeling The Incubation Period Of Anthrax, Ron Brookmeyer, Elizabeth Johnson, Sarah Barry

Ron Brookmeyer

Models of the incubation period of anthrax are important to public health planners because they can be used to predict the delay before outbreaks are detected, the size of an outbreak and the duration of time that persons should remain on antibiotics to prevent disease. The difficulty is that there is little direct data about the incubation period in humans. The objective of this paper is to develop and apply models for the incubation period of anthrax. Mechanistic models that account for the biology of spore clearance and germination are developed based on a competing risks formulation. The models predict …

Modeling An Outbreak Of Anthrax, Ron Brookmeyer

Ron Brookmeyer

Introduction

On October 2, 2001 a sixty-three-year-old Florida man who worked as a photo editor at a media publishing company was admitted to an emergency department complaining of nausea, vomiting, and fever. His symptoms began four days earlier on a recreational trip to North Carolina. The man died shortly thereafter. An astute clinician quickly made the surprising diagnosis of inhalational anthrax, which is a serious and deadly disease. The diagnosis was surprising because inhalational anthrax is extremely rare; only 18 cases were reported in the United States between 1900 and 1978. Public health officials at first believed that the Florida …

Modeling The Optimum Duration Of Antibiotic Prophylaxis In An Anthrax Outbreak, Ron Brookmeyer, Elizabeth Johnson, Robert Bollinger

Ron Brookmeyer

A critical consideration in effective and measured public health responses to an outbreak of inhalational anthrax is the optimum duration of antibiotic prophylaxis. We develop a competing-risks model to address the duration of antibiotic prophylaxis and the incubation period that accounts for the risks of spore germination and spore clearance. The model predicts the incubation period distribution, which is confirmed by empirical data. The optimum duration of antibiotic prophylaxis depends critically on the dose of inhaled spores. At high doses, we show that exposed persons would need to remain on antibiotic prophylaxis for at least 4 months, and considerable morbidity …

Statistical Models And Bioterrorism: Application To The U.S. Anthrax Outbreak, Ron Brookmeyer, Natalie Blades

Ron Brookmeyer

In the fall of 2001 an outbreak of inhalational anthrax occurred in the United States that was the result of bioterrorism. Letters contaminated with anthrax spores were sent through the postal system. In response to the outbreak, public health officials treated over 10,000 persons with antibiotic prophylaxis in the hopes of preventing further morbidity and mortality. No persons receiving the antibiotics subsequently developed disease. The question arises as to how many cases of disease may actually have been prevented by the public health intervention of antibiotic prophylaxis. A statistical model is developed to answer this question by relating to the …

Farm Disease Crises In The United Kingdom: Lessons To Be Learned, Michael C. Appleby

State of the Animals 2003

Over the last fifteen years, a diverse succession of disease-related crises has befallen farm animal and food industries in the United Kingdom. Some have involved animal health, with little risk to humans. Some have involved human health, with animals acting as a reservoir for infection but little affected themselves. Some, however— including the most alarming— have involved both animal and human health through zoonoses, diseases transmittable from animal to human. All of these crises are linked in the public mind and in many commentaries, and indeed there are issues that many of them share. The most common of these is …
