represents a considerable public concern worldwide, with farm animals often recognised as an important reservoir. This study gives an overview of the prevalence and serotype diversity of over a 5-year period in the meat production chain in Estonia. Data on human salmonellosis over the same period are provided.
surveillance data from 2016 to 2020 were analysed.
The prevalence of at the farm level was 27.7%, 3.3% and 0.1% for fattening pigs, cattle and poultry, respectively. . Derby was the most prevalent serotype at the farm level for fattening pigs and . Dublin for cattle. The top three serotypes isolated at the slaughterhouse and meat cutting levels were . Derby, monophasic . Typhimurium and . Typhimurium with proportions of 64.7%, 9.4% and 7.0%, respectively. These serotypes were the top five most common serotypes responsible for human infections in Estonia. . Enteritidis is the main cause (46.9%) of human salmonellosis cases in Estonia, but in recent years, Enteritidis has not been detected at the slaughterhouse or meat cutting level.
In recent years, monophasic . Typhimurium has become epidemiologically more important in Estonia, with the second-highest cause in human cases and third-highest among the most prevalent serotypes of in the meat chain.
在全球范围内引起了公众的广泛关注，农场动物常被视为重要的传染源。本研究概述了爱沙尼亚肉类生产链中5年内沙门氏菌的流行情况和血清型多样性。同时提供了同期人类沙门氏菌病的数据。
分析了2016年至2020年的监测数据。
育肥猪、牛和家禽农场层面沙门氏菌的流行率分别为27.7%、3.3%和0.1%。德比是育肥猪农场层面最常见的血清型，都柏林是牛的最常见血清型。在屠宰场和肉类切割环节分离出的前三种血清型分别是德比、单相鼠伤寒沙门氏菌和鼠伤寒沙门氏菌，比例分别为64.7%、9.4%和7.0%。这些血清型是爱沙尼亚导致人类感染的最常见的五种沙门氏菌血清型。肠炎沙门氏菌是爱沙尼亚人类沙门氏菌病病例的主要病因（46.9%），但近年来，在屠宰场或肉类切割环节未检测到肠炎沙门氏菌。
近年来，单相鼠伤寒沙门氏菌在爱沙尼亚的流行病学重要性日益增加，在人类病例中是第二大病因，在肉类链中最常见的沙门氏菌血清型中排名第三。
