Seventy broiler farms were surveyed from March 2016 to June 2018. Samples of fresh droppings were collected using gauze socks, and a questionnaire was completed with the farmers. Persistence was defined as an infection with the same serovar before and after cleaning and disinfection (C/D) of poultry houses. <i>Salmonella</i> spp. was found to persist on 27% of the farms. Cleaning concrete surrounding areas (OR = 0.23) and disinfecting silos (OR = 0.17) reduced the risk of pathogen persistence. An analysis of infections of pests found in the vicinity of the farms confirmed their role in the persistence of <i>Salmonella</i> spp. Fifteen percent of the pests wHeliyone06278https://www.ebi.ac.uk/biostudies/studies/S-EPMC7969330biostudies-literatureRisk factors for <i>Salmonella enterica</i> subsp<i>. enterica</i> persistence in broiler-chicken flocks on Reunion Island.PMC7969330Cardinale EEtheves MAHascoat JChoisis NDalleau FGallard VAlvarez SfalseRisk factors for <i>Salmonella enterica</i> subsp<i>. enterica</i> persistence in broiler-chicken flocks on Reunion Island.This study was conducted to identify the main risk factors for <i>Salmonella</i> spp. persistence in broiler flocks in Reunion Island.
