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.
