Biological invasions are a growing threat to biodiversity, food security, and economies. Rising pressure from increased global trade requires improving border inspection efficiency. Here, we depart from the conventional consignment-by-consignment approach advocated in current inspection standards. Instead, we suggest a broader perspective: evaluating border inspection regimes based on their ability to reduce propagule pressure across entire pathways. Additionally, we demonstrate that most biosecurity pathways exhibit superspreading behavior, that is, consignments from the same pathway have varying infestation rates and contain rare right-tail events (also called overdispersion). We show that greater overdispersion leads to more pronounced diminishing returns, with consequences on the optimal allocation of sampling effort. We leverage these two insights to develop a simple and efficient border inspection regime that can significantly reduce propagule pressure compared to current standards. Our analysis revealed that consignment size is a key driver of biosecurity risk and that sampling proportional to the square root of consignment size is near optimal. In testing, our framework reduced propagule pressure by 31 to 38% compared to current standards. We also identified opportunities to further improve inspection efficiency by considering additional pathway characteristics (i.e., overdispersion parameters, zero inflation, relative risk, sampling cost, detectability) and developed solutions for these more complex scenarios. We anticipate our result will mitigate biological invasion risk with significant implications for biodiversity conservation, food security, and economies worldwide., (© 2024 The Authors.

In the era of globalization, biological invasions are one of the most serious social issues. Thus, managing its impact is an urgent task. It is essential to control nonnative species before they become established. However, it is insufficient to address establishment debt, which occurs when a nonnative species has been introduced into an area but has not yet been established in the wild. In particular, unintentionally introduced or contaminated organisms of the aquatic ornamental pet trade are referred to as "hitchhikers" and have not received much attention in the context of establishment debt. To understand the nature of establishment debt, including that of aquatic hitchhikers, I propose the monitoring of nonnative species inhabiting artificial isolated waters, such as indoor aquariums, and the construction of a database using environmental DNA metabarcoding. This idea would be an effective nonregulatory management approach when implemented broadly, at the country level. Furthermore, implementation of this strategy in combination with border biosecurity and field monitoring may promote accurate prioritization, rapid species identification, and effective invasion pathway assessment.

Background: In Southeast Asia from 2004 to 2006, highly pathogenic avian influenza (HPAI) resulted in culling 45 million birds and jeopardizing sustainable agricultural production. HPAI is highly virulent; small-scale farms present a high-risk environment for disease transmission between animals and humans. We investigated how attitudes toward HPAI influence water-related biosecurity mitigation behaviors on small-scale farms in Vietnam using the conceptual framework Social Cognitive Theory., Method: We analyzed a secondary cross-sectional data set from northern (Thai Binh) and southern (An Giang) provinces in Vietnam, describing a stratified randomized selection of 600 small-scale farmers who were interviewed using questionnaires and in-person interviews. Logistic regression analysis and odds ratios were used to examine relationships between factors influencing HPAI attitudes, social norms, perceived importance, and behaviors (α = 0.10) RESULTS: Concern about the severity of HPAI was significantly associated with increased perceived importance for all water management biosecurity methods (p < 0.01). Media and/or peer influence had negative effects on perceived importance to practice water-related biosecurity (p < 0.10). High importance of practice water-related biosecurity resulted in high uptake (p < 0.05). Past experiences with HPAI were significant in predicting perceived importance; none were significant in describing behavior uptake., Discussion: Biosecurity guidelines may not be consistent with management styles of Vietnamese small-scale farms; perceived importance of a behavior may be an important mediating variable. Gaps exist in uptake of water management practices as biosecurity for HPAI, potentially negatively affected by peer and media influence. Our results should be of interest to public health and policy authorities addressing HPAI mitigation., (© 2021 Society for Risk Analysis.)

In this study, we analyzed the characteristics of the most cited papers regarding species distribution predictive models (SDPMs). We found 173 papers on SDPMs that received at least 100 citations until 2013, according to the Thomson Reuters Web of Science database. These papers were published between 1991 and 2012, with the majority published between 2002 and 2012, indicating the rapid development of this field of research. The papers were published mainly in journals listed in the ecology category on the Web of Science. Almost half of the top-cited papers were methodological, introducing novel modeling methods and software. Applied papers on species conservation and biodiversity management, climate change, phylogeography, and biosecurity also figured out among the top-cited papers. Researchers from 174 institutions in 27 countries, with 51% of the papers being internationally collaborative and 69% inter-institutionally collaborative, published the papers. Among all 173 papers, seven papers stood out as having a great impact on the field, receiving more than 1000 citations each. Finally, the results found by analyzing the top-cited SDPMs papers support the view of a growing interest and rapid development of this research field over the past two decades. The top-cited papers primarily focused on the development and evaluation of novel methods to improve the performance of the models, and thus, to better predict the environmental suitability for species in applied studies.

Introduction of pests and diseases through trade is one of the main socio-ecological challenges worldwide. Although Binomial sampling inspection at the border can reduce pest entry risk, it is common for consignments to fail inspection, wasting resources for both exporter and importer. Outsourcing the inspection to the exporting country could reduce the cost of inspection for both parties. However, there is then a need to assess the quality of the offshore inspection. In this paper, we develop an inverse method combining past inspection data on the pathway, an onshore inspection sample, and the Beta-Binomial model to infer the sample size of the offshore inspection. We illustrate the method on two case studies: the importation of live plants through germplasm into Australia and the importation of pelleted seeds in New Zealand. In these case studies, we found that detecting four to five infested units in a single onshore inspection was typically sufficient to significantly doubt the presence of a compliant offshore inspection. We also ran a simulation experiment to quantify the statistical power to reject or accept the presence of compliant offshore inspection in practice: In highly infested pathways, we could detect the absence of offshore inspections after inspecting five consignments onshore. Less infested pathways required inspecting 20 to 60 consignments onshore. Our study demonstrates that Binomial sampling onshore can be used to assess the quality of offshore inspections., (© 2022 The Ecological Society of America.)

While improvements in genomic sequencing speed and availability have decreased the time to pathogen identification, crucial legal, policy, and technical knowledge gaps related to the risks a novel pathogen might pose and what an appropriate response should involve may still remain. Early detection of biological threats, whether naturally occurring or manmade, is critical for initiating a robust biodefense and public health response. [Extracted from the article]

Introduction of pests and diseases through trade is one of the main socioecological challenges worldwide. Targeted sampling at border security can efficiently provide information about biosecurity threats and also reduce pest entry risk. Prioritizing sampling effort requires knowing which pathways are most infested. However, border security inspection data are often right-censored, as inspection agencies often only report that a consignment has failed inspection (i.e., there was at least one unit infested), not how many infested units were found. A method has been proposed to estimate the mean infestation rate of a pathway from such right-censored data (Chen et al.). Using simulations and case study data from imported germplasm consignments inspected at the border, we show that the proposed method results in negatively biased estimates of the pathway infestation rate when the inspection data exhibit overdispersion (i.e., varying infestation rates among different consignments of the same pathway). The case study data also show that overdispersion is prevalent in real data sets. We demonstrate that the method proposed by Chen et al. recovers the median infestation rate of the pathway, rather than its mean. Therefore, it underpredicts the infestation rate when the data are overdispersed (in right-skewed distributions, the mean is above the median). To allow better monitoring and optimizing sampling effort at the border, we recommend that border protection agencies report all the data (the number of infested units found together with the sample size of the inspection) instead of only that the consignment failed inspection., (© 2020 Society for Risk Analysis.)

Simple Summary: Porcine reproductive and respiratory syndrome virus (PRRSV) infection in sows results in reduced animal welfare, poor breeding herd performance, and economic loss to farmers. The best way to reduce the effects of PRRSV is to prevent its entry into swine breeding herds through improvements in farm biosecurity. To accomplish this goal, the concept of Next Generation Biosecurity (NGB) was developed. A recent publication demonstrated that the practice of a comprehensive, science-based program of biosecurity (NGB COMPLETE) which incorporated science-based biosecurity protocols targeting direct and indirect routes of PRRSV transmission, significantly reduced PRRSV incidence risk in breeding herds compared to a partial program (NGB INCOMPLETE). This new communication follows up on this earlier paper and brings new information by reporting significant differences in key performance indicators between NGB COMPLETE breeding herds versus NGB INCOMPLETE herds over that original 2-year period across the same swine production system. It also supplements the earlier paper with data from a third consecutive year of reduced PRRSV incidence risk, resulting in a PRRSV incidence risk of 8.0% across all breeding herds for the entire three years. In closing, this is further evidence demonstrating that NGB, while not perfect, brings value to farmers through sustainable prevention of PRRS and improved productivity. Porcine reproductive and respiratory syndrome virus (PRRSV) is a globally significant pathogen of pigs. Preventing the entry of PRRSV into swine breeding herds enhances animal health and welfare. A recently published retrospective cohort study reported significant differences in PRRSV incidence risk between breeding herds that practiced Next Generation Biosecurity (NGB) COMPLETE, versus herds that practiced a partial approach (NGB INCOMPLETE) over a 2-year period. This follow-up communication builds on this previous publication and brings new information regarding statistical differences in key performance indicators (KPIs) from 43 NGB COMPLETE herds and 19 NGB INCOMPLETE herds during disease years 1 and 2. Statistically significant differences included higher total born/farrow and pigs weaned/female along with a reduced pre-weaning mortality and wean to 1st service interval, as well as a 0.91 increase in the number of pigs weaned/mated female/year. In addition, this communication reports that PRRSV incidence risk throughout disease years 1–3 was 8.0%, and that the association of NGB status (COMPLETE vs. INCOMPLETE) and disease burden for the cumulative 3-year period was statistically significant (p < 0.0001). These findings support previously published data that NGB, while not perfect, provides sustainable prevention of PRRSV, and may help improve herd productivity. [ABSTRACT FROM AUTHOR]

Farm biosecurity has gained increasing attention worldwide during the last decades because of its role in reducing the occurrence of diseases and improving animal performance. Recently, recommendations to reinforce the concept of farm biosecurity in lower- and middle-income countries have been advised. Therefore, this review aims to provide a comprehensive description of the methods and tools used to assess biosecurity compliance in livestock farms in Africa and formulate recommendations. The present review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews guidelines. Peer-reviewed studies reporting biosecurity assessment in poultry, cattle, pig, goat, or sheep farms in Africa were included. Five databases were searched with no date restrictions. A total of 41 studies across 17 countries were finally selected. Selected studies were all published after 2008, and an increasing trend in the number of papers published per year was noticed. In total, 41 different methods for biosecurity assessment were found to be used in African countries, meaning that even within the same country, the same animal species, and the same farming system, different methods were utilized. In many papers, the methods used for biosecurity evaluation were poorly described. In addition, during the biosecurity assessment, measures related to the purchase of laying hens, egg transport and management, calves, calving and dairy management, and nursery units were almost not considered. These measures should be contemplated in future studies since they are related to important risk factors for the introduction and dissemination of infectious diseases. Interestingly, some measures not considered in European biosecurity tools were identified in the selected studies. The observed high difference in methods used may be due to the lack of regulations on biosecurity in African countries; therefore, the authors recommend the development and implementation of a harmonized and contextualized method for the assessment of biosecurity in livestock farms in Africa.

Livestock markets are pathological sites in which contrasting biopolitical regimes compete to reconfigure agricultural practices and identities. Whilst the circulation of cattle is central to agricultural geographies, little is known about the practices of cattle trading or the role of livestock markets in cattle purchasing. Drawing on recent attempts to conceptualise the process of marketisation, this paper seeks to invigorate research into livestock markets. Specifically, the paper conceptualises cattle purchasing as a market encounter in which socio-technical arrangements, devices and bodily performances entangle cattle and farmers, enabling markets to work. Using data collected from interviews, focus groups and participant observation at livestock markets in England, the paper makes two contributions. Firstly, the paper shows how farmers' cattle purchasing practices are organised by practices of 'fluid engineering' that seek to maintain the 'farm system'. Secondly, the paper shows how at livestock markets, these strategies are mediated by front and backstage 'market displays' by farmers and auctioneers which produce market price through a series of performances that are carefully spatially and temporally ordered. Specifically, these displays perform specific rural and agricultural identities, such as the 'genuine' or 'good' farmer. In creating these spatial frames, frontstage displays diminish the relevance of backstage displays that rely on abstract calculations by distant others. The paper therefore reveals the intense entanglements and socio-technical work that is required to make cattle markets function and their wider relevance for the management of livestock diseases.

This paper firstly compares the structure of agricultural supply chain ecosystem from both internal members and external environment and analyzes the information transfer mechanism of information flow, capital flow, logistics and other energy and information in the supply chain. The importance of supply chain ecological coordination mechanism and its functional components are also discussed in depth. On this basis, the biosecurity strategy system of agricultural products supply chain management is constructed and the biosecurity strategy of supply chain management is proposed. Finally, the biosafety risk of agricultural products supply chain management in the e-commerce environment is assessed, and a multi-dimensional risk assessment index is proposed. Meanwhile, risk management theory is applied to provide a detailed analysis of the likelihood, loss, contagiousness, controllability and comprehensiveness of risks. The study showed that the risk indices were relatively high with the average values of 85% for transportation and storage technology risk, 76% for additive abuse risk, and 70% for agricultural input improper risk, respectively. The research in this paper provides new ideas and methods for biosafety management in the supply chain of agricultural products. [ABSTRACT FROM AUTHOR]

In recent years, in order to save land resources and ensure biosecurity, multi-storey buildings for pig rearing are replacing traditional flat-floor methods in pig farms domestically and internationally. However, the precision, stability, and adaptability of pig feed transportation in multi-storey buildings have brought certain challenges to the development of large-scale pig raising. The uniqueness of this paper lies in the comprehensive review of recent research advances in various transportation machinery and feeding systems from the perspective of both pig feed transportation and feeding systems compared to other papers that singularly present pigs' feed transportation machinery or feeding systems. In addition, this paper provides an outlook on the potential for coupling power sources for pig feed transportation and pig transportation, providing insights for future research and development. First, the paper comprehensively reviews feed transportation machinery in multi-storey pig rearing, highlighting their advantages and challenges. Then, it explores the commonly used feeding systems in large-scale pig rearing and their limitations. Finally, the paper summarizes the current issues in pig feed transportation in multi-storey buildings and examines future development trends. [ABSTRACT FROM AUTHOR]

With the rapid advances in technology and life science, biological security is now at a defining moment. The mandate of the 2022 Biological and Toxin Weapons Convention 9th Review Conference emphasised the urgent need for new tools to strengthen the Convention. In this paper, we review the development and efforts of the International Nuclear Security Education Network (INSEN) to provide examples of best practice for implementation of the newly founded International Biological Security Education Network (IBSEN). Learning from the lessons of the INSEN, the sustainability of the network through continuous engagement of its members is essential for the further development of global biosecurity education.

The article presents information on a study conducted to address biosecurity and DNA quality issues in abalone aquaculture using Whatman FTA Elute Microcards. The reagent present on this cards, together with the cotton paper, form a chemically treatedmatrix optimized for biosafety through the inclusion of nuclease inhibitors and antimicrobial agents. Two adult Haliotis rubra were collected from a commercial farm in Tasmania for the study. It was found that DNA quantity and quality varied widely between the samples. The sequence and genotype results of FTAs-extracted DNA conformed to those observed from the routine commercial extraction method used for the study.

The emergence of advanced biotechnologies has intensified in recent years. The rapid development of these biotechnologies has had a wide and profound impact globally, with the majority on the frontier of biosecurity technologies. The global biosecurity situation is currently highly challenging, with the characteristics of internationalization, extremely serious harm, and complex development. The misuse and abuse of biotechnologies are common, which thereby endanger biosecurity. The international community and governments have attached great importance to cutting-edge biotechnologies and are implementing laws and regulations to control and prevent biosecurity-related influences. By tracking the frontier progress of the new technologies generated from gene editing, gene drives, synthetic biology, and related cross-disciplines as applied in the biosecurity field, we analyzed the development trends in biotechnologies and their potential influence. On the one hand, this paper proposes that there is an urgent need for global cooperation to formulate management, control strategies, and measures for cutting-edge technologies in biosecurity to jointly promote their sound development. On the other hand, the international community should jointly shoulder the responsibility for safeguarding biosecurity and restrict the biotechnologies to rational applications within legal and ethical frameworks. This paper aims to provide a reference for the prevention of misuse and abuse of biotechnologies and support global cooperation in biosecurity governance. [ABSTRACT FROM AUTHOR]

This paper brings together animals, death, and digital geographies to examine the sharing of dead animal imagery on social media by conservationists in Aotearoa New Zealand (NZ). It is particularly concerned with two key questions: (1) Why (and how) do dead animals attract support for conservation? (2) How are personal feelings about animal death navigated in the public space of social media? In answering these questions, this paper extends geographical research on animals' affective allures (including online) beyond the realm of the living, and contributes to ongoing conversations around how to live with ‘unwanted others’. I draw on interviews with the leaders of conservation groups about whether, when, and why they post images of dead animals and kill counts, which I collectively refer to as ‘death media’. I show that because some viewers (at times disparaged as ‘precious’) were expected to respond with physical and/or moral disgust, conservationists typically only share death on ‘mainstream’ platforms if it is sufficiently sanitised or incorporated into positive narratives—though more commonly, death is absent from these platforms. Other audiences, particularly volunteer trappers, were described as ‘pragmatic’ or ‘bloodthirsty’; death was shared with these audiences to cultivate affects of hope and solidarity, in a context where killing can affectively feel like success. Yet even those comfortable with both killing and viewing death media at times expressed regret and sadness at the deaths of pests; they simply avoid sharing these feelings online. Death media thus perpetuate the public un‐grievability of ‘pests’, despite indications that even those who do the work of killing may experience sadness privately. I conclude by asking: what would be needed for pests killed for conservation to become grievable online, and how could doing so change relationships between humans and ‘pest’ animals?

Simple Summary: This paper addresses the need for effective biosecurity due to disease challenges, the emergence and re-emergence of new pathogens, the growing pressure of antibiotic restrictions, and the welfare and sustainability of livestock farming. It introduces the Biorisk® External platform, a cloud-based visitor control system that enhances data management and biosecurity compliance protocols. This system analyzes visitation patterns, revealing trends and categorizing visits by authorization and risk status. This network analysis also allows for the identification of 'superspreader' farms that represent a high epidemiological risk. The results advocate for integrating technology into biosecurity protocols to optimize standard operation procedures (SOPs) to improve animal health and mitigate economic losses, highlighting the importance of data-driven decision-making in modern livestock farming. This study explores the critical challenges the livestock sector faces, particularly those related to biosecurity, animal welfare, and antibiotic use restrictions. It highlights the need to implement advanced information and communication technologies to enhance operational sustainability and decision-making. We introduce the Biorisk® External platform, a cloud-based visit control system designed to optimize biosecurity management by accurately tracking visitor activity through QR codes and GPS geolocation. During a 6-month study period from July to December 2023, we analyzed visits to 142 different swine production sites and 30 vehicle movement patterns. The analysis revealed trends in visitation patterns and compliance with biosecurity SOPs. The software categorized visits as authorized (A), not authorized with access (NAWA), and not authorized without access (NAWOA), providing a framework to assess biosecurity risks. Additionally, network analysis identified interconnected farms, which were classified as 'superspreaders', highlighting their considerable risk of disease transmission. This study advocates for the integration of digital systems in livestock operations to improve biosecurity measures, facilitate real-time data input, and support informed decision-making. By enhancing biosecurity protocols through technology, the livestock industry can better safeguard animal health, increase operational efficiency, and reduce potential economic losses associated with disease outbreaks.

Simple Summary: Maintaining a sustainable supply of animal protein is the mission of the global swine production industry. The entry of infectious pathogens to swine populations can cause significant animal welfare issues, increase the use of antibiotics, challenge environmental stability, and interrupt/reduce the supply of pork; therefore, preventing pathogen entry is critical to achieve its mission using science-based biosecurity programs. Biosecurity is the application of science-based protocols to minimize the risk of pathogen entry. The objective of this review is to summarize basic biosecurity terms and concepts, review the transmission of porcine reproductive and respiratory syndrome virus (PRRSV) and the biosecurity protocols designed to mitigate these risk factors, and discuss how the swine industry is applying Next Generation Biosecurity to prevent PRRSV infection of the breeding herd. The prevention of disease introduction into swine herds requires the practice of science-based protocols of biosecurity that have been validated to reduce the risk of the entry of targeted pathogens. The fundamental pillars of biosecurity include bio-exclusion, biocontainment, and bio-management. Biosecurity protocols must be science-based, a way of life, continuously validated, cost-effective, and benchmarked over time. This paper will review these concepts, the direct and indirect routes of transmission of porcine reproductive and respiratory syndrome virus (PRRSV), and the interventions that have been designed and validated to prevent infection of the breeding herd. It will close with a review of Next Generation Biosecurity, describing how a science-based approach is being used to prevent PRRSV infection in breeding herds from a large commercial pork production system in the US.

This paper unravels the intimate and irritant more-than-human encounters in hostel accommodation used by migrant farm workers in regional Australia. These are communal places of inhabitancy that draw attention to the intersecting concerns of highly mobile populations, seasonal labour, migration politics, and the socio-material relationships that flourish within such spaces. I examine the presence of bed bugs and other nonhumans through interviews with farm workers, hostel operators and managers, and ethnographic observations, to highlight broader implications of such 'communal' forms of living. The communal nature of living alongside others is challenging, especially when the arrangement is for work and migration, rather than leisure, and due to a lack of affordable housing options. The paper uses a more-than-human lens to bring into dialogue the mobilities of these workers with notions of communal living, which are intrinsically tied to visa conditions and labour migration. In doing so, the paper contributes to broadening the understandings of how and where mobilities take shape, and the impacts that more-than-human agencies have on day-to-day life in communal living situations.
