Carcass Disposal Research Articles

Being prepared for an avian influenza epidemic with a One Health approach: a cartographic study to identify animal carcasses burial sites in central Italy.

During epidemics, pandemics, or animal disease outbreaks, the large-scale disposal of carcasses presents greater environmental and biosecurity challenges. In Europe, disposal through a rendering plant is the preferred option, but the on-site carcasses burial may be authorised due to logistical and economic advantages. This study utilised a comprehensive GIS-based approach and focuses on the challenges and strategies for large-scale carcass disposal, particularly in the context of avian influenza outbreaks in the Lazio Region of Italy. Integrating data from official geospatial sources regarding presence of environmental restrictions and regulations, factors affecting susceptibility to groundwater contamination, factors affecting soil stability over time, potential burial sites were identified. The resulting map provides decision-makers with valuable information for prompt and efficient response during disease outbreaks. The study underscores the importance of a multidisciplinary approach involving veterinarians, epidemiologists, GIS experts, and geologists. Further research and international consensus are essential to standardize the selection of geographic variables/layers to use in similar projects. This study significantly contributes to the preparedness of environment, health and animal/human interface events.

A case study of the 2023 highly pathogenic avian influenza (HPAI) outbreak in tern (Sternidae) colonies on the east coast of the Republic of Ireland

ABSTRACT Capsule:HPAI H5N1 had a significant impact on breeding Common Terns Sterna hirundo, Arctic Terns Sterna paradisaea and Roseate Terns Sterna dougallii on the east coast of the Republic of Ireland (ROI) in 2023, with a lesser impact on Sandwich Terns Thalasseus sandvicensis and only two cases among Little Terns Sternula albifrons. Aims: To document the outbreak of HPAI H5N1 in the tern colonies on the east coast of ROI during the 2023 breeding season. Methods:Precautions were taken from the start of the breeding season, including personal protective equipment (PPE) and safe operating procedures. Regular meetings were held between BirdWatch Ireland and the National Parks and Wildlife Service (NPWS) to respond to the emerging situation. Once HPAI was confirmed in a colony, all ringing and nest visits were stopped. Carcass removal was carried out at all affected colonies and most carcasses were incinerated. Results: Common Terns suffered the highest mortality across all colonies in 2023, with smaller but notable numbers of dead Roseate Terns and Arctic Terns, but very few Sandwich Terns and only two Little Tern deaths were attributed to HPAI. Conclusion: Regular meetings between relevant organizations were invaluable in preparing for outbreaks and ensuring an adaptive approach as the situation changed over time and between colonies. There was no way of knowing if the actions taken were effective, as the pattern of virus spread between species and sites remains poorly understood. Future clarity over the role of various state agencies and other relevant bodies in responding to HPAI in wild birds, greater sharing of real-time information, and pre-arranged agreements to ensure rapid testing and disposal of carcasses, would be useful to ensure an effective response to future outbreaks.

Comparing efficiencies of population control methods for responding to introductions of transboundary animal diseases in wild pigs

Introductions of transboundary animal diseases (TADs) into free-ranging wildlife can be difficult to control and devastating for domestic livestock trade. Combating a new TAD introduction in wildlife with an emergency response requires quickly limiting spread of the disease by intensely removing wild animals within a contiguous area. In the case of African swine fever virus (ASFv) in wild pigs (Sus scrofa), which has been spreading in many regions of the world, there is little information on the time- and cost-efficiency of methods for intensively and consistently culling wild pigs and recovering carcasses in an emergency response scenario. We compared the efficiencies of aerial operations, trapping, experimental toxic baiting, and ground shooting in northcentral Texas, USA during two months in 2023. Culling and recovering carcasses of wild pigs averaged a rate of 0.15 wild pigs/person hour and cost an average of $233.04/wild pig ($USD 2023) across all four methods. Aerial operations required the greatest initial investment but subsequently was the most time- and cost-efficient, costing an average of $7266 to reduce the population by a standard measure of 10 %, including recovering carcasses. Aerial operations required a ground crew of ∼7 people/helicopter to recover carcasses. Costs for reducing the population of wild pigs using trapping were similar, although took 13.5 times longer to accomplish. In cases where carcass recovery and disposal are needed (e.g., response to ASFv), a benefit of trapping was immediate carcass recovery. Toxic baiting was less efficient because both culling and carcass recovery required substantial time. We culled very few wild pigs with ground shooting in this landscape. Our results provide insight on the efficiencies of each removal method. Strategically combining removal methods may increase overall efficiency. Overall, our findings inform the preparation of resources, personnel needs, and deployment readiness for TAD responses involving wild pigs.

Incidência de linfadenite granulomatosa suína no ano de 2023 em frigorífico localizado no Triângulo Mineiro, Minas Gerais

Despite the increase in pig production in Brazil, challenges such as the spread of diseases in pig populations and public health concerns, such as the transmission of viruses and bacteria, require constant vigilance during the slaughter of these animals. In this context, granulomatous lymphadenitis (LG) in pigs is a subclinical disease caused mainly by non-tuberculous mycobacteria, with Mycobacterium avium hominissuis being the most prevalent in pigs and humans. The detection of infected animals occurs during slaughter, resulting in losses due to the disposal of viscera and carcasses. This study aimed to report the incidence of LG in a slaughterhouse located in the city of Uberlândia, Minas Gerais, during the year 2023. More than one million slaughtered animals were evaluated, of which more than 100 thousand showed some non-compliance, resulting in 596 cases of LG identified. The data suggest a low incidence of LG in the Triângulo Mineiro region, attributed to advances in disinfection practices and widespread knowledge about the disease. Furthermore, a seasonal pattern was observed in the occurrence of LG, with higher incidences in the coldest months of the year. Factors such as lack of hygiene in facilities, inadequate food supply and the presence of birds can contribute to the spread of the disease. It is concluded that despite the low occurrence in the studied region, LG continues to be a concern due to its economic impact and the need for constant surveillance and improvements in management and hygiene practices.

Prioritisation of emerging and epidemic-prone diseases and risk factors in India’s three western states using the One Health Risk and Disease (OHRAD) prioritisation tool

BackgroundThere have been numerous outbreaks of infectious diseases to date, and out of them, six events have been declared as Public Health Emergencies of International Concern by the World Health Organization (WHO). The outbreaks have been unprecedented, and the sudden anxiety associated with these makes the situation more complicated. Prioritisation of diseases has been a common process in public health, and it is important to identify infectious diseases that are important for human health. In addition, a One Health approach requires taking also animal origin and related risk factors for infectious diseases into account.MethodsState-level co-creation workshops were conducted in Gujarat, Rajasthan, and Maharashtra, the three western states of India. One Health Risk and Disease (OHRAD) prioritisation tool was used to prioritise emerging and epidemic-prone diseases and their risk factors.ResultsThe risk factors and diseases were scored using the OHRAD tool, and the ranks were obtained. Avian flu by A(H5N1), A(H7N9), and A(H9N2), swine flu by A(H1N1), A(H1N2) and A(H3N2), dengue, rabies, leptospirosis, bovine tuberculosis, salmonellosis, chikungunya, soil-transmitted helminths, and brucellosis were some of the 10 diseases prioritised in all the three western states of the country. Similarly, the presence of mosquito breeding sites near houses or workplaces, open defecation, poor hand hygiene, poor personal hygiene, reluctance to follow disease prevention measures and improper carcass disposal were prioritised as the risk factors for diseases in all three states.ConclusionThe emerging and epidemic-prone diseases and risk factors that are prioritised reflect state-specific scenarios and the gravity of the situation concerning risk factors for disease outbreaks. This can help in allocating resources and increasing efforts in the prevention and control of these diseases.

Dead on the Beach? Predicting the Drift of Whale Remains Improves Management for Offshore Disposal

Whale mortality and strandings have increased in recent years, with deceased whales often brought to landfill. However, the disposal of whale remains offshore holds significant ecological importance and can be a culturally and ethically sensitive approach. Moreover, offshore disposal mitigates potential risks associated with onshore whale remains disposal, such as the spread of diseases and the logistical challenges of managing large carcasses. A challenge with offshore disposal is defining the best release location to avoid the remains drifting ashore or into shipping channels. Here we compared the drift model outputs using a drift forecast model (SARMAP) for a 14 m whale carcass that was moved offshore in southeast Queensland, Australia, and fitted with a satellite tracker over an observation period of 150 h until positioning signal ceased. The modelling was conducted using different ocean products (BLUElink, HYCOM, and Copernicus), which showed a good agreement with the tracked whale carcass, albeit with changing wind conditions and contrasting currents flowing northward along the coast and, further offshore, flowing south. This case study illustrated that wind was the foremost driver of carcass drift due to the surface area above the water surface. The drift forecast simulations allowed for a reliable prediction of the floating whale drift that can assist authorities with decision making. Offshore disposal of whale carcasses is a sustainable practice but requires good planning and scientific assessment.

Awareness and adoption of farm biosecurity practices in commercial dairy, pig and poultry farms of Uttar Pradesh (India).

India's livestock sector has been facing significant losses due to episodes of disease outbreaks since time immemorial. Hence, biosecurity measures are very important to maintain and improve animal health along with prevention of disease outbreak. Keeping these facts into consideration, the study was proposed with an objective to assess the existing biosecurity practices adopted by the commercial dairy, pig and poultry farms. The current study was undertaken in the state of Uttar Pradesh as it is the leading state in milk and meat production. A total of 120 farmers were selected randomly including 40 each practicing commercial dairy, pig and poultry farming. An ex-post facto research methodology was used with face-to-face interview and observation to collect data. The biosecurity practices were assessed under seven dimensions such as, location and design of farm, restricted access, isolation and quarantine, cleaning and disinfection, management of feed and water, disposal of carcass, manure and waste, and health management. Results elicited that about 50% of the farmers had medium level of adoption who adopted 18-34 practices out of 51 practices. The average overall adoption score was 34.17 out of 51 (67%) which makes an overall adoption gap of 33%. Maximum adoption gap was seen in case of restricted access (43%) whereas minimum gap in adoption was seen in case of management of feed and water (27%). Pig and poultry farmers showed significantly higher biosecurity measures than dairy farmers (p < 0.05). The more significant contributors to the adoption of biosecurity measures were the level of knowledge of the farmers (p < 0.01). Other factors such as education, income, herd/flock size, Information and Communication Technology utilization, number of trainings also had a significant contribution (p < 0.05) in actual implementation of biosecurity. Hence, better understanding of these measures among the farmers must be ensured by hands on training along with proper demonstration of various procedures involved in maintaining farm biosecurity is need of the hour.

Prion forensics: a multidisciplinary approach to investigate CWD at an illegal deer carcass disposal site

ABSTRACT Infectious prions are resistant to degradation and remain infectious in the environment for several years. Chronic wasting disease (CWD) has been detected in cervids inhabiting North America, the Nordic countries, and South Korea. CWD-prion spread is partially attributed to carcass transport and disposal. We employed a forensic approach to investigate an illegal carcass dump site connected with a CWD-positive herd. We integrated anatomic, genetic, and prion amplification methods to discover CWD-positive remains from six white-tailed deer (Odocoileus virginianus) and, using microsatellite markers, confirmed a portion originated from the CWD-infected herd. This approach provides a foundation for future studies of carcass prion transmission risk.

IJCM_219A: A “One Health” Model for Prevention and Control of Anthrax in Koraput, Odisha, India

Background: Anthrax, a neglected zoonotic disease caused by Bacillus anthracis, poses a significant threat in Odisha, India, particularly in the tribal district of Koraput, which has reported numerous human cases and deaths but lacks consistent robust surveillance. Objectives: This study aimed to pilot a “One Health” surveillance model in Koraput, involving community health workers, para-veterinarians, and block- level teams in outbreak investigations. Methodology: As part of the “One Health Approach to Anthrax Control in India (OHAI)” project Odisha University of Agriculture and Technology (OUAT), in collaboration with the Departments of Animal Husbandry and Health and Family Welfare, Government of Odisha, initiated prospective laboratory-based anthrax surveillance in three blocks of Koraput. Confirmed cases in animals were identified via microscopic, culture, or PCR testing for Bacillus anthracis. Community awareness programs and rapport-building exercises were conducted with human and veterinary officials at the block and district levels following the detection of outbreaks. Results: Between March and June 2023, five anthrax outbreaks were detected in Koraput, with four involving both cutaneous human and animal deaths and one in animals only. Livestock losses included cattle (27), goats (2), and buffalo (1). Of the 38 samples collected (blood, bone, tissue, and soil), 11 (35%) tested positive for anthrax by RT-PCR. OUAT rapidly communicated results (&lt;24 hours) to the state health department, leading to joint investigations and control measures, including livestock vaccination, safe carcass disposal, and medical outreach camps for screening and prophylaxis. In total, five district/block level meetings and two state-level consultations were held, culminating in a zoonotic roadmap draft, which included an anthrax prevention and control action plan. Conclusion: The study’s adoption of the One Health framework facilitated a rapid response to anthrax outbreaks in Koraput, effectively managing both human and animal cases. This model presents a viable approach for controlling anthrax in endemic areas of India.

Biosecurity practices in the dairy farms of southern Brazil.

Biosecurity refers to a set of practices that prevents and/or controls the introduction, spread, and elimination of harmful biological agents in a production system. In this study, we aimed to survey the biosecurity practices and determine their correlation with the size of production systems. A biosecurity assessment form was provided to 69 farms in the Campos Gerais region of Paraná, Brazil. The questionnaire was divided into two sections: general and bovine viral diarrhea virus- and bovine herpesvirus type-1-specific sections. The general section covered topics on traffic control, quarantine and animal isolation, hygiene practices, carcass disposal, and disease monitoring/control. The specific section consisted of questions on the reproductive and respiratory factors, use of antimicrobials, and vaccination schedule. The 69 farms were also classified into small (≤ 61), medium (62-201), and large (≥ 202) size farms based on the number of lactating cows. Moreover, multiple correspondence analysis (MCA) was performed between the biosecurity measures and farm size. The main risk factors and variability were related to the traffic control of people, animals, and vehicles/equipment, animal quarantine/isolation, and hygiene practices. MCA revealed that the small farms exhibited a lack of biosecurity measures, including those related to traffic control, animal quarantine, and hygiene. In medium-size farms, contact between bovine animals of different ages and difficulty in animal isolation in the quarantine system were among the main risk factors. In contrast, isolation of sick animals was easy, but the need to frequently purchase cattle was an important risk factor in large farms. These results highlight the relationship between biosecurity measures and farm size, providing valuable insights for the development of better biosecurity plans for production systems.

What are the Strategies for Controlling Hydatid Cysts in Developing Countries?

Hydatid cysts (HC), caused by the tapeworm of the genus Echinococcus, pose a significant public health challenge in many developing countries. These cysts primarily affect livestock, such as sheep, cattle, and goats, but can also infect humans, the two most important forms in humans are cystic echinococcosis (hydatidosis) and alveolar echinococcosis, leading to serious health complications. Control measures for HC are crucial to lessen the impact on both human and animal health. This editorial explores the possible strategies for controlling HC in developing countries, focusing on prevention, surveillance, treatment, and community education [1,2]. Preventing HC in developing countries may require a multifaceted approach. One crucial aspect is controlling the transmission of Echinococcus eggs from infected animals to humans. This involves implementing measures such as deworming programs for livestock, proper disposal of infected animal carcasses, and promoting good hygiene practices among livestock handlers and population Furthermore, community education plays a vital role in preventing HC. Educating individuals about the risks associated with handling infected animals, the importance of proper hand hygiene, and the benefits of cooking meat thoroughly can help reduce the transmission of the parasite [2]. Effective surveillance is essential for monitoring the prevalence of HC and identifying high-risk areas in developing countries. Surveillance systems should involve regular screening of both livestock and humans for Echinococcus infection. This can be achieved through the use of diagnostic tests such as serological assays and imaging techniques like ultrasound. Additionally, active surveillance programs can help detect outbreaks early and facilitate timely intervention measures. Collaborative efforts between government agencies, healthcare providers, and veterinary professionals are crucial for establishing robust surveillance systems in resource-limited settings [3, 4]. Treating HC in developing countries often presents challenges due to limited access to healthcare resources and diagnostic tools. However, prompt diagnosis and treatment are essential to prevent complications such as cyst rupture and dissemination. Surgical intervention remains the primary treatment option for HC, involving the removal of the cysts and surrounding tissue. In some cases, minimally invasive techniques such as puncture–aspiration–injection–re-aspiration (PAIR) may be used as an alternative to surgery, particularly in resource-limited settings. In addition to medical treatment, access to safe and effective anthelmintic drugs is crucial for controlling HC. Ensuring the availability of these medications and training healthcare providers in their appropriate use are essential components of treatment strategies in developing countries [5,6]. Educating communities about HC, their transmission, and prevention measures might play a significant role in sustainable control efforts. This can be achieved through various educational initiatives, including workshops, community outreach programs, and the distribution of educational materials. Furthermore, engaging with local community leaders and healthcare providers can facilitate the adoption of preventive measures within communities. Emphasizing the importance of early detection, timely treatment, and proper hygiene practices can empower individuals to take proactive steps in protecting themselves and their livestock from HC. In conclusion, controlling HC in developing countries requires a comprehensive approach that addresses prevention, surveillance, treatment, and community education. By implementing targeted interventions and fostering collaboration between government agencies, healthcare providers, community stakeholders, and the scientific community However, extensive research and investigations in this regard are highly recommended.

Detection of infectious bursal disease virus (IBDV) antibodies in backyard poultry by using indirect enzyme linked immunosorbent assay

Infectious bursal disease virus (IBDV) causes infectious bursal disease in poultry and poses a major challenge to the poultry industry globally. This study aimed to measure seroprevalences and so detect exposure to IBDV in backyard poultry in the selected zone of Horro Guduru Wollega. A cross-sectional study was conducted from January 2021 to November 2022. Blood samples were collected for serum extraction from 384 backyard chickens in the Horro and Horro Bulluq districts. IBDV antibody detection was conducted using an indirect ELISA serological diagnostic test. Questionnaires assessed poultry owners? knowledge and health/hygiene management practices regarding the disease. The over all seroprevalence of IBDV was 14.84%. Significant variations in seroprevalence were seen based on district, bird age, bird sex, and flock size. Limited owner experience (just 1-3 years), disposing of carcasses in pits, and poor hygiene on the backyard premises were associated with higher IBDV seroprevalence. In conclusion, IBDV seroprevalence was linked to chicken management practices. Recommendations include improving poultry management among owners to control IBDV. The study indicates backyard poultry in the region have considerable IBDV exposure, and control should focus on improving management practices identified as high-risk, such as pit disposal of carcasses and poor hygiene.

Surviving the summer: foot-and-mouth disease virus survival in U.S. regional soil types at high ambient temperatures.

Foot-and-mouth disease (FMD) is one of the most economically significant global livestock diseases. In the U.S., economic optimization models run in 2011 demonstrate the highest mean epidemic impact of a potential FMD outbreak in California would occur in livestock-dense regions, resulting in national agriculture losses of $2.3 to $69.0 billion. In the case that an FMD outbreak occurred in the U.S., mass depopulation, carcass disposal, and disinfection protocols for infected premises have been designed to prevent further viral spread. Because the FMD virus (FMDV) is spread mechanically via the environment, characteristics of viral environmental stability are important. Temperature and adsorption to soil particles are reported to be the most important factors affecting general virus survival; however, how much these factors alter FMDV survival has not been tested. Soil samples were examined from typical U.S. regions containing the highest cattle population densities: Tennessee, Georgia, Nebraska, California, Pennsylvania, Kentucky, and Iowa. Soils were spiked with known quantities of FMDV and FMDV stability was evaluated over seven distinct time points between 0 hours and 12 days at incubation temperatures of 25°C and 37°C to represent a range of typical ambient temperatures during the summer. FMDV stability was quantified via virus titration. Virus decayed faster at higher ambient temperatures for all soils, but decay at 25°C was faster in some soils. Consequently, areas with high ambient temperatures may have lower between-farm transmission rates, slower outbreak spread, and simpler farm decontamination. This study provides a helpful exploration into understanding soil survival of the virus. Additional investigations into FMDV survival across different soil types will aid in developing better disinfection protocols and further refining regional viral transmission rate estimates.

Kyasanur Forest Disease: An Epidemiological Investigation and Case-Control Study in Shivamogga, Karnataka, India-2022.

Kyasanur Forest Disease (KFD) is a viral zoonosis reported from Karnataka, India. We investigated cases in the Shivamogga district, Karnataka, to describe the epidemiology and identify risk factors in the affected block in 2022. A case was defined as a laboratory-confirmed KFD-positive resident of Shivamogga from 1 January-31 May 2022. We extracted the records of KFD cases from district surveillance. We conducted a 1:3 case-control study in the Thirthahalli block. We enrolled laboratory-confirmed KFD-positive Thirthahalli residents from January to May 2022 as cases, and residents without "fever with myalgia" as controls. We reported adjusted odds ratios (aOR) with 95% confidence intervals (CI). Shivamogga reported 35 cases, with a median age of 46 (4-75) years, of which 51% were men, and one death. Among 25 cases and 90 controls, knowledge of avoiding recent monkey death sites was low (cases = 0%, controls = 11%). Monkey death sites within 500m [aOR = 8.6 (1.8-41.9)] and household tick exposure [aOR = 3.7 (1.3-10.7)] were independent risk factors. This was a laboratory-confirmed cluster of KFD cases in Thirthahalli, with residence near a monkey death site and household tick exposure considered significant risk factors. We recommend evaluating monkey carcass disposal procedures and increasing awareness of tick protective measures.

Suitability of anthrax (Bacillus anthracis) in the Black Sea basin through the scope of distribution modelling.

The Black Sea basin has a strategic geographic location bridging Asia and Europe and depends on traditional livestock practices for their local economies. Anthrax, a zoonotic bacterial disease caused by Bacillus anthracis, poses a significant global threat impacting public health, food security, pastoralist communities, and national economies. The disease is endemic or sporadic in the Black Sea basin, however, the study of its distribution has seldom been addressed, despite its burden and the presence of historical B. anthracis burial sites in the region. The viability of B. anthracis in a particular region is going to be influenced by multiple environmental factors, such as soil composition, climate, vegetation, and host abundance. For characterizing the potential distribution of B. anthracis in the Black Sea basin and assessing the potential for anthrax outbreaks, we applied an ecological niche modelling framework using the Maxent algorithm. This machine-learning algorithm models species distributions based on presence data and background information from a specified calibration region. We analyzed multiple variable combinations and proposed a novel approach for interpreting in-risk anthrax areas. Our findings underscored the importance of host abundance to the anthrax dynamics in the region. We identified anthrax-suitable areas spanning central and eastern Türkiye, Armenia, southern Georgia, southern Russia, Bulgaria, southern and eastern Romania, Hungary, Moldova, and southern Ukraine, which align with findings from previous global and regional studies on the potential suitability of anthrax. The insights gained from our research may help to develop targeted interventions, such as awareness and educational campaigns about anthrax, supervision of anthrax-infected carcasses disposal, and the promotion of livestock vaccination in high-risk areas. Additionally, these results can inform policies to mitigate the spread of anthrax in pastoralist communities in the Black Sea basin and foster collaboration between veterinary and public health entities on anthrax control.

Avian Infectious Bronchitis Virus: Molecular Detection in Southwestern Ethiopia Chickens.

Infectious bronchitis virus (IBV) is a significant threat to poultry worldwide, but its status in Ethiopia remains understudied. Thus, this study aimed to detect the virus and associated risk factors in South West Ethiopia. Ninety oropharyngeal swab samples were purposively collected from symptomatic chickens located in Jimma town, Seqa Chekorsa, and Tiro Afeta woredas of the Jimma zone between November 2021 and April 2022 to detect IBV virus by using RT-PCR. A side-by-side questionnaire was administered to assess risk factors. Total RNA was extracted, reverse transcription polymerase chain reaction (RT-PCR) was conducted, and products were visualized under UV light. The overall proportion of IBV was 16.6% (15/90). No statistical association was observed between any of the animal risk factors and the detection of the virus (P=0.57, 0.586, and 1). However, the proportion of birds infected by the virus was higher in males, exotic breeds, and adults compared to females, local breeds, and young birds. Similarly, none of the management risk factors had a significantly different effect on virus detection (P=0.25, 0.09, 0.088, and 0.726). However, improper carcass disposal (OR = 0.43, 95% CI: 0.13-1.4), lack of veterinary services (OR = 2.7, 95% CI: 0.8-8.3), and the presence of wild birds/rodents (OR = 4.4, 95% CI: 0.88-22.3) were associated with increased IBV risk but not cleaning of feeders/drinkers (OR = 1.1, 95% CI: 0.2-4.8). These findings underscore the need for enhanced biosecurity practices and further research to implement informed IBV control strategies in Ethiopia.

The importance of vultures for ecological stability and human society

As human society continues to evolve and advance, urbanization has become increasingly prevalent in various countries. Consequently, the natural environment is confronted with a growing array of challenges. It is imperative for individuals to enhance awareness of the significance of vultures to both humanity and the natural environment. This essay will primarily elucidate the significance of vultures, encompassing their role within human culture and the natural environment. Research has indicated that vultures possess a scarcity as significant, sizable scavengers within the natural environment. They play a crucial role in impeding the spread of infectious diseases arising from deceased organisms, while also expediting the progression of vital ecological cycles, such as the carbon and nitrogen cycles. Vultures play a significant role in agricultural growth by aiding in the disposal of animal carcasses. Furthermore, due to their longstanding coexistence with humans, vultures have acquired symbolic significance in various religious traditions worldwide, representing spiritual potency. The significance of human beings is widely acknowledged in numerous geographical areas. Enhanced focus on vultures is vital for safeguarding the growth of their population, facilitating the expeditious advancement of science and technology, mitigating ecological harm, and upholding the symbiotic coexistence of humanity and the natural world.

Animal, human, and environmental perspectives on anthrax in Bangladesh

BackgroundIn Bangladesh, the zoonotic transmission of anthrax from animals to humans poses substantial challenges for prevention and control programs, especially in resource-constrained settings. A comprehensive literature review was conducted focusing on anthrax infections in animals, humans, and the environment to enable better design of prevention and control strategies. Materials and methodsWe followed PRISMA guidelines to collect data on anthrax infection in animals and humans from reports between 1980 and January 2023. We used a standardized data extraction template to collect data on study location, year, hosts, deaths and risk factors responsible for anthrax occurrences at the animal, human and environmental sectors. Subsequently, we conducted a thorough analysis of the data gathered to identify the factors responsible for anthrax occurrences and to propose updated strategies for anthrax prevention and control. ResultsOf the 27 articles analyzed, 20 focused on animal or human anthrax, while seven addressed environmental contaminations. A total of 6354 cases of anthrax infection in animals were recorded, with 998 fatalities and an overall case fatality of 15.7 %. In humans, inadequate knowledge about anthrax and its transmission was a significant factor. Risk factors for human cutaneous anthrax included activities such as slaughtering diseased animals and contact with contaminated raw meat or blood. Risky practices such as disposal of animal carcasses in floodwaters or water bodies were observed in some areas, contributing to the persistence of the anthrax pathogen in the environment. ConclusionsOur study highlights the necessity of a multisectoral One Health approach to effectively control and prevent anthrax outbreaks in both animals and humans. This approach should include comprehensive vaccination programs, social and behavioral change activities, environmental management, and the establishment of surveillance systems. Implementing these recommendations will be crucial in addressing the complex challenges posed by anthrax in low-resource settings.

These advancements offer a promising foundation for more effective, environmentally conscious, and sustainable approaches to managing animal mortalities during disease outbreaks.

Wildlife as sentinels of compliance with law: An example with GPS‐tagged scavengers and sanitary regulations

Abstract Monitoring compliance with environmental laws is essential to overcoming possible implementation shortfalls jeopardizing their effectiveness. Besides improving our ecological understanding of wildlife, remote tracking technologies also allow us to take advantage of such ecological knowledge to use wildlife as sentinels of compliance with law. We illustrate this sentinel potential of wildlife using GPS tracking of large scavengers with complementary functional traits (i.e. 21 griffon vultures and 13 wolves) to assess compliance with EU sanitary regulations allowing livestock carcass disposal in the field. Wildlife sentinels allowed the systematic evaluation of 489 livestock carcasses left in the field, which revealed an important mismatch between on‐paper and in‐reality implementation of these regulations. While &lt;45% of the carcasses were placed in authorized areas, compliance with all the criteria required by the regulations on livestock carcass disposal (e.g. from carcass characteristics such as species, age or production system to its location far away from water, buildings or roads) ranged from 0% to 4.2%, with no major differences between regions with uneven implementation. Major gaps in compliance pointed towards insufficient and over‐bureaucratized designation of scavenger feeding zones, where livestock carcass disposal is authorized. The indiscriminate nature of distance criteria from carcasses to watercourses, buildings and infrastructure further affected compliance. Synthesis and applications. GPS‐tagged scavengers allow the on‐ground monitoring of carcasses, the addressing of potential risks for wildlife, livestock and human health, the quantitative assessment of compliance with the law and would improve estimates of carcass availability, substantially contributing to more effective legislation enforcement. Our results show the huge potential of GPS‐tagged wildlife as sentinels for monitoring compliance to enhance the environmental rule of law.
