Data was collected in 68 markets across five provinces, with up to 10 pork vendors per market randomly selected. Microbiological data were collected through cut pork samples and cutting boards swabs (n = 396), along with structured questionnaires and observations with vendors (n = 486). Cutting board swabs were analyzed for TBC only, while cut pork was tested for both TBC and <em>Salmonella</em>. Linear and generalized linear mixed-effects models were constructed to identify risk factors for TBC and <em>Salmonella</em> prevalence. The overall <em>Salmonella</em> prevalence in cut pork was 64.4 % (255/396) and was significantly higher in southern provinces (86.8 %) compared to the north (47.5 %, <em>p</em> &lt; 0.01).

This study investigated the molecular prevalence and associated risk factors of <em>A. marginale</em> across four climatic zones in Iran. A cross-sectional design with multi-stage stratified sampling was utilized. Blood samples from 1952 clinically healthy cattle were analyzed using nested-PCR targeting the <em>msp4</em> gene. The overall prevalence was 23.2 % (95 % CI: 21.3–25.0), with considerable regional variation; it was highest in the Persian Gulf zone at 44 % and lowest in the Caspian zone at 10.5 %. Sub-desert regions exhibited the highest infection rates (44.2 %), while mountainous and plain areas showed lower prevalence (26.1 % and 20.6 %, respectively). Phylogenetic analysis of 16S rRNA sequences revealed distinct clustering of Iranian isolates, suggesting potential genetic divergence from global strains. Key risk factors identified through multivariable logistic regression included grazing practices (OR = 2.02, <em>P</em> = 0.029), inadequate barn sanitation (OR = 2.35, <em>P</em> = 0.002), infrequent ectoparasiticide application (OR = 2.92, <em>P</em> &lt; 0.001), proximity to other farms (OR = 3.12, <em>P</em> = 0.001), and co-rearing with other livestock species (OR = 2.73, <em>P</em> = 0.036). Seasonal variation was notable, with higher infection rates during warm, dry periods (OR = 2.86, <em>P</em> &lt; 0.001).

This study assessed four sampling strategies for detecting ASFV-infected animals in suspected growing pig farms within the first 14 days of the introduction of either a high- or moderate-virulence ASFV strain.

The informative sampling method was further divided into sequential method, which ranked pens by descending viral load probability, and cluster &amp; random method, which selected pens at random from high and low viral load clusters. Each pen-selection method was examined with different sample sizes. We calculated the sensitivity of each approach as the probability of detecting at least one ASFV-positive pig per farm. Results showed that sampling 30 pens with one pig per pen using the target &amp; random pen-selection method yielded the highest detection sensitivity, even in the presence of other co-circulating diseases that interfere with the accurate identification of clinical ASFV cases.

This study presents a data-driven Walk-Over Weighing System (WoWS) enhanced with Fast Fourier Transform (FFT) and machine learning (ML) algorithms to provide a non-invasive, automated solution for real-time weight estimation in cattle. Dynamic weight signals from 86 dairy cows were collected twice daily during routine milking using a walk-over-weighing (WoWS) platform at the Burdur MAKU farm. Raw force-time signals were pre-processed and transformed using FFT to reduce noise and extract spectral-domain features relevant for weight estimation. Six ML models, including Support Vector Regression (SVR), were evaluated for prediction performance. The SVR model yielded the highest accuracy (MAE: 2.3 kg, R²: 0.999). The system's functionality was further extended through integration with Internet of Things (IoT) frameworks for real-time data collection and anomaly detection. Heatmaps and time-aligned weight distributions validated the system’s robustness under dynamic field conditions. This FFT- and AI-enhanced WoWS offers a scalable and effective tool for herd-level health surveillance by enabling continuous monitoring, early detection of abnormal weight trends (e.g., weight loss due to disease onset or inadequate feeding), and remote decision-making. The proposed system supports One Health principles by reducing manual handling, minimizing animal stress, improving welfare, and lowering labor demands, thereby contributing to more sustainable and efficient livestock-farming practices.

We examined the social, technical and regulatory rules which drive the production of small-scale poultry farms selling directly to consumers, and then analyzed the barriers and opportunities for implementing biosecurity measures. This study analyzed qualitative data from 36 semi-structured interviews conducted in two French poultry production areas between January and October 2023. The interviews were recorded and transcribed, then thematically analyzed to identify recurring themes. Our results show that small-scale poultry farmers share strong values rooted in their autonomy over decision-making and traditional farming practices that are based on free-range livestock farming, high-value products, and local know-how. Despite widely diverse settings, farmers in this production sector demonstrate a strong sense of professional identity. Our results also show that recurrent HPAI epidemics and associated regulations have disrupted small-scale farming systems. Verbatims revealed tensions between biosecurity guidelines and several aspects of small-scale production, including farming practices (such as visitors’ access to farms), values (free-range farming), workload, and financial sustainability. To move beyond these biosecurity tensions, some initiatives have been developed, such as personalized training and advice for small-scale farmers. However, these solutions only reach a small proportion of producers.
