However, data on biosecurity awareness and implementation in small-scale or backyard (hereafter referred to as small-scale) holdings across Europe are lacking. While the risk posed by these farms is generally regarded as limited, they represent a diverse group of farmers and do play a role in disease introduction and spread. The aim of this study was to explore veterinarians' perspectives on small-scale farming in Europe, including the frequency of farm visits, the definition of small-scale farming, the current status of biosecurity, and the most important measures to prevent pathogen introduction and spread. A multidisciplinary team developed a comprehensive survey to collect veterinarians' perspectives on biosecurity in small-scale farms. The survey was translated into 16 languages, digitalised, and distributed online between July and December 2024 by participants of COST Action BETTER. Data were analysed descriptively, and clusters of veterinarians were distinguished using multiple correspondence analysis. In total, 346 veterinarians from 23 countries participated in the survey. There is no standard definition of small-scale farming throughout Europe. According to the participating veterinarians, a small-scale farm was defined as having a median number of fewer than 20 cattle, 30 small ruminants, 13 pigs, or 99 heads of poultry. Three clusters of veterinarians were identified based on geographical location, field experience, biosecurity training, and perceived biosecurity awareness within the small-scale farming community. Biosecurity measures already applied in small-scale farming included fencing, carcass management, and biosecurity measures related to purchasing and feeding practices. According to the participating veterinarians, the most important biosecurity measures for small-scale farms to prevent pathogen introduction and spread included factors related to the introduction of animals, such as quarantine facilities, testing for health status, and purchasing animals from farms with a high health status. Besides factors related to the introduction of animals, hygiene measures and fencing were also frequently indicated as the most important biosecurity measures. Nevertheless, significant differences were found between the clusters regarding the importance of specific biosecurity measures. This study provides valuable insights into the perceived awareness, implementation, and desired biosecurity measures in European small-scale farming and underscores the importance of integrating small farms into “One Health” strategies, given their potential role in the spread of infectious diseases.</div></div>","PeriodicalId":21083,"journal":{"name":"Research in veterinary science","volume":"203 ","pages":"Article 106089"},"PeriodicalIF":1.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146119720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
