This evaluation aims to understand how effective biosecurity investments were towards reducing the susceptibility of a turkey farm to HPAI and what types of farms were more likely to make those types of investments. Factors associated with lower chances of being infected included having any hens, making any temporary biosecurity investments to the farm since 2015 such as temporary wild bird mitigation, and making specific permanent biosecurity investments such as improving feed bins, vehicle wash stations, and barn ventilation systems. Also, those farms that raised any hens, those that participated in the NPIP, and those without livestock access around turkey barns were more likely to make biosecurity investments. These findings aid in informing producers, integrators, and public policy on how to reduce the spread of HPAI to benefit both the economy and longevity of the poultry industry.</div></div>","PeriodicalId":20413,"journal":{"name":"Preventive veterinary medicine","volume":"244 ","pages":"Article 106624"},"PeriodicalIF":2.2,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144632414","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}

This study aimed to evaluate the worldwide distribution of <em>G. duodenalis</em>, as well as to determine its prevalence and identify risk factors associated with infections in sheep and goats. A comprehensive systematic review was performed utilizing international databases to collect relevant studies. A random-effects meta-analysis was applied to estimate the global prevalence of <em>G. duodenalis</em>. A total of 104 studies from 32 countries, published up to January 2025, fulfilled the inclusion criteria. The overall global prevalence of <em>G. duodenalis</em> in small ruminants was found to be 14 % (95 % CI: 11 %-17 %). Notably, the highest prevalence were recorded in temperate and tropical regions situated between latitudes −60° to 60° (18.9 %; 95 % CI: 14.7 %-24.0 %), and in areas above 45° latitude in both northern and southern hemispheres (21.3 %; 95 % CI: 13.4 %-32.2 %). Seasonal analysis revealed peak prevalence occurring during winter months (16.1 %; 95 % CI: 9.4 %-26.0 %).

Subjective and objective knowledge of nutrition and hygiene were assessed. Dog owners feeding raw meat diet at least twice per week were less aware of the health risks of raw meat than those that did not, and exhibited lower knowledge about pathogenic hazards. Additionally, they perceived commercial dry diets as nutritionally riskier than raw diets. Nutritional knowledge might help mitigate some, but not all, of the risks associated with incorrect feed composition.
