Fourteen focus group discussions and three in-depth interviews were completed and analysed in Norway, Scotland and Ireland with salmon production managers, health experts and health inspectors from government and certification bodies (<em>N</em> = 44). Results showed that the participants valued the role that reliable data can play in salmon health management. Factors that influence data utilisation for decision-making were identified using the data lifecycle concept (i.e., the flow from collection to analysis and sharing). Generally, stakeholders preferred timely, ideally automatically recorded, standardised and high-quality data and wished for a tool that offers convenient access to data and facilitates data search and compilation. Furthermore, the comfort with which stakeholders use data tools varied, ranging from some stakeholders welcoming support from decision support tools to others preferring to rely mostly on their personal experience when analysing data. While some data sharing is mandatory (e.g., reporting of mortality from industry to authorities), the participants reported other forms of data sharing (e.g., informal exchange of information, not data, across companies). Lack of contextual factors contributes to a hesitancy to share data (e.g., lack of perceived benefits and fear over potential misuse). In Norway, stakeholders were more open to share data between the salmon industry and authorities. Being used to reporting more data, combined with operating in a larger industry where individual farms are not easy to single out from aggregated statistics, may have contributed to gaining trust among participants in Norway. However, in all three countries, some participants were reluctant to share data with the public or tied it to preconditions (e.g., ensuring it was presented in the right context, with explanations on the background for mortality), while others highlighted positive effects of sharing data, such as benchmarking and increased focus on preventive measures.

To improve the welfare of smallholder livestock keepers, dairy farming extension programs are essential, as they stimulate knowledge transfer, resource accessibility, and adoption of best practices. This study employed a quasi-experimental research design, engaging a total of 431 livestock keepers, comprising 221 treated participants and 210 control group members from the Engaruka, Lepurko, and Selela wards in Monduli District, Arusha, Tanzania. Utilizing the Double Hurdle model and Propensity Score Matching (PSM), the study estimated the determinants of participation and the impacts of these interventions on welfare. The results revealed that demographic factors, social capital, and educational attainment significantly influenced participation rates in dairy farming extension programs. Additionally, the Average Treatment on the Treated (ATT) analysis showed that participation led to an increase of 5.751 liters per day in milk production and a monthly income boost of 11,670 TSHS. However, mean income differences showed that participants earned 55,010 TSHS more than non-participants. This suggests that while extension programs contribute to higher incomes, pre-existing differences such as access to resources, experience, and herd size also contribute to this disparity. These findings informs that effective extension services can markedly improve the welfare of Maasai livestock keepers by providing critical training and resources that enable higher productivity and economic resilience. By fostering social networks, facilitating market access, and enhancing knowledge among farmers, extension programs play a vital role in empowering these communities. Therefore, targeted strategies that promote inclusivity, improve access to resources, and incorporate educational initiatives are recommended to maximize the benefits of these programs.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"239 ","pages":"Article 106511"},"PeriodicalIF":2.2,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consumption of contaminated food products of animal origin contributes to majority of the NTS illness outbreaks. Poultry, an important protein source, is considered the main animal source for NTS. However, contamination with different serotypes of NTS may be attributed to various animal hosts. We aimed to determine the prevalence, trends, and potential risk factors for NTS contamination of food sources in Israel. A dataset including 192,340 test results for the detection of NTS contamination in food products in Israel between 2007 and 2021 was analyzed. Food samples were collected as part of routine testing and targeted programs for NTS detection from different facilities, such as food factories and slaughterhouses. The collected food samples included: non-thermally treated (raw) and mainly thermally treated ready-to-eat (RTE) products. Data were summarized and associations between NTS detection and different covariates were estimated using either: (i) Poisson regression model; or (ii) ꭕ2-tests. The odds ratio (OR) or prevalence ratio and 95 % confidence intervals (CI_95 %) were calculated. The number of food products tested for NTS identification and further serotype classification has declined in recent years. However, the percentage of NTS positive results increased over time, reaching 18.11 % positive samples by 2021. The risk for NTS contamination was significantly higher in raw vs. RTE products: OR (CI_95 %) = 290.60 (239.39–352.76), p &lt; 0.001. The percentage of samples found positive for NTS in RTE products varied between sources, yet remained below 0.49 % for each source. However, in raw products, the NTS prevalence ranged between 1.05 % and 35.03 %, with food products from the chicken source significantly more positively associated with NTS contamination in comparison beef, fish, pig and turkey sources. Imported food, and slaughterhouses had a significantly higher prevalence of NTS contamination compare to factories food hygiene testing. With certain facilities, within each category, demonstrating significantly higher contamination compared to others. Moreover, the ten most common serotypes reported in human infections throughout this period were mostly found in chicken and turkey sources. The identification of certain sources and facilities/importers/slaughterhouses which may pose higher risk for NTS contamination was possible despite the declining resources invested in sampling and classification of NTS isolates in recent years.

In order to harmonise these tests, we tried to adjust their cut-offs so that there is a maximum of agreement between them. Using the results of the three ELISAs applied to 1258 cattle, 1474 goat and 1432 sheep serum samples collected in France, we identified the cut-offs that maximised Hubert’s kappa, an agreement coefficient applicable to more than two tests, using a differential evolution algorithm for optimisation. We then evaluated the effect of changing the cut-offs. In particular, we estimated the sensitivities and specificities of each test at the optimal cut-offs using a latent class model. While the manufacturer’s cut-offs of the three tests were 30, 40 and 40 respectively, regardless of the species, the cut-offs that maximise the agreement are 44.7, 30.8 and 84.3 for cattle, 6.6, 18.8 and 49.8 for goats, and 26.2, 50.9 and 88.6 for sheep. By using these cut-offs instead of those provided by the manufacturers, the observed proportion of disagreement between the tests is reduced by approximately half, and the diagnostic performances and apparent prevalence are more consistent from one test to another. The use of these species-specific cut-offs allows for better harmonisation of the tests. However, before implementing these new cut-offs, it is essential to assess the measurement uncertainty around them to ensure that the analytical performances of the tests are maintained.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"239 ","pages":"Article 106509"},"PeriodicalIF":2.2,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143643994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incidence risk of IMI was similar for the various selective dry cow treatments when antimicrobials were administered together with an internal teat sealant, either at quarter or cow level. Also, they did not differ from the evaluated blanket dry cow treatment interventions or when an internal teat sealant was applied alone. Selective dry cow therapy with internal teat sealant is therefore likely a suitable intervention option to simultaneously maintain a low incidence risk of IMI and a high cure risk of IMI, all the while lowering the antimicrobial use in dairy herds.

We examined the link between the infrastructure and operations of the dairy farm and the antibiotic resistance potential in India, which is the highest producer and consumer of dairy products globally. We sampled sixteen dairy farms in the Dehradun district, India, that varied in their herd size, infrastructure, and operational features during winter, summer, and monsoon. We collected samples of dung, manure, wastewater, manure-amended, and control soil from these farms. We quantified six antibiotic resistance genes (ARGs) (&lt;em&gt;sul&lt;/em&gt;1, &lt;em&gt;sul&lt;/em&gt;2, &lt;em&gt;par&lt;/em&gt;C, &lt;em&gt;mcr&lt;/em&gt;5, &lt;em&gt;erm&lt;/em&gt;F, and &lt;em&gt;tet&lt;/em&gt;W), an integron integrase gene cassette (&lt;em&gt;int&lt;/em&gt;I1), and 16S rRNA gene copies as an indicator for total bacterial count. We observed that the infrastructure and the operations of the dairy farms were significantly associated with antibiotic resistance potential in the dairy environment. For example, with increased ventilation and exposure to external weather, the levels of &lt;em&gt;sul&lt;/em&gt;2 (x͂=10&lt;sup&gt;−1.63&lt;/sup&gt;) and &lt;em&gt;par&lt;/em&gt;C (x͂=10&lt;sup&gt;−4.24&lt;/sup&gt;) in manure increased. When farmers administered antibiotics without veterinary consultation, the relative levels of &lt;em&gt;int&lt;/em&gt;I1 (x͂=10&lt;sup&gt;−2.36&lt;/sup&gt;), &lt;em&gt;sul&lt;/em&gt;2 (x͂=10&lt;sup&gt;−1.58&lt;/sup&gt;), and &lt;em&gt;tet&lt;/em&gt;W (x͂=10&lt;sup&gt;−3.04&lt;/sup&gt;) in manure were lower than the cases where professional advice was sought.

The use of early warning systems based on the systematic monitoring of health data and the identification of syndromes, known as syndromic surveillance systems, has been used for early identification of human and animal health events. Despite the marked development in animal health syndromic surveillance (AHSyS) systems in the last two decades, challenges for the implementation of functional AHSyS systems continue to exist, with limited research investigating stakeholder perspectives on these systems. The current project aimed to identify key drivers and barriers of livestock industry private sector stakeholder participation in syndromic surveillance in New South Wales (NSW), Australia. To achieve this aim, a qualitative study was conducted using semi-structured interviews with seven international syndromic surveillance experts and 17 private sector stakeholders, including abattoirs, knackeries, animal health consultants/veterinarians, research institutions, livestock industries, pharmaceutical companies, private veterinary laboratories and a national animal health body. The expert consultation identified that despite the significant advancements on AHSyS in the last two decades, implementation of AHSyS systems continue to be limited, with key considerations being the lack of data standardisation, issues with data privacy, data integration and the limited consideration of stakeholder needs for supporting decision-making and benefits from participation. Strong iterative collaboration with all stakeholders with high levels of trust, appropriate resourcing, and balance between regulatory and industry needs are required for supporting system sustainability. Animal health surveillance was important for all stakeholders in the consultation, however understanding of syndromic surveillance systems was limited. A significant amount of health and production data is already being collected by stakeholders; however, the data type and data collection platforms are highly variable, confirming the complexity for standardisation and integration. The major stakeholder concerns were in relation to privacy, protection of information and the potential commercial and/or trade implications of data misuse or misrepresentation, the required additional resourcing for participating and the regulatory nature of such system. Despite these concerns, all stakeholders showed interest in being involved in further discussions on the development of an AHSyS system. A successful AHSyS system should consider representativeness and quality of the data, simplicity in data collection and processing, clear benefits and value of the outputs, and strong collaboration across all relevant stakeholders.

This study examined the ASF outbreak in Davao Region, Southern Philippines, by analyzing its spatiotemporal patterns and identifying risk factors. The investigation involved three parts: determining spatiotemporal patterns using spatial autocorrelation and hotspot analysis, conducting Key Informant Interviews (KIIs) with government veterinarians to identify local risk factors, and fitting a conditional logistic regression model to estimate the effects of biosecurity and farming practices on the likelihood of ASF occurrence. A sharp decline in incidence rates and non-recurring hotspots of ASF-affected barangays (villages) were observed, which may have been influenced by community quarantines and 1–7–10 zoning protocols. However, ASF hotspots continuously shifted towards the northeast provinces of the region. Thematic analysis of collected data from KIIs highlighted six general areas of ASF management and control that have posed challenges: farm biosecurity, traders' roles, farmers' capabilities, slaughterhouse practices, veterinary services, and response gaps. Regression analysis revealed that biosecurity measures for trade vehicles and cleaning practices were associated with a decreased likelihood of ASF risk, while swill feeding, inadequate waste management, and improper disposal of diseased pigs were associated with an increased likelihood of ASF risk. These findings provide critical insights for managing ASF spread while supporting smallholder farmers, strengthening the livestock industry’s resilience against similar diseases.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"239 ","pages":"Article 106495"},"PeriodicalIF":2.2,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143552424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
