Salmonellosis is the second most common foodborne bacterial gastroenteritis in humans in Finland and worldwide. In Finland, a national salmonella control program covering cattle, pigs, and poultry, as well as the meat and eggs obtained from them, has been in place since the country joined the EU in 1995. To identify trends in the incidence of salmonellosis and to reflect on their causes, we analyzed case data from the Finnish Infectious Disease Register (FIDR) from 1995 to 2022 and outbreak data from the national food and waterborne outbreak register (the FWO register) in the period 2010-2022. From 1995-1999 to 2015-2019, the incidence of salmonellosis decreased by 66% and 63% for domestic and travel-related cases, respectively. Most salmonellosis cases (72%) were travel-related, and, of them, 27% were infected in Southeast Asia. The most common serovars were . Typhimurium and . Enteritidis (38% and 19% of domestic cases, and 7% and 39% of travel-related cases). During 2010-2022, sp. was reported as a cause in 31 foodborne outbreaks. In 14 of them, the source was identified at foodstuff level, and 12 sources were of foreign origin. The results of this study indicate that the national salmonella control program may have prevented domestic human infections in Finland.
沙门氏菌病是芬兰乃至全球第二常见的食源性细菌性肠胃炎。在芬兰，自1995年该国加入欧盟以来，就实施了一项涵盖牛、猪、家禽及其所产肉类和蛋类的全国沙门氏菌控制计划。为了确定沙门氏菌病发病率的趋势并思考其成因，我们分析了1995年至2022年芬兰传染病登记处（FIDR）的病例数据以及2010年至2022年期间国家食源性和水源性疫情登记处（FWO登记处）的疫情数据。从1995 - 1999年到2015 - 2019年，国内病例和与旅行相关病例的沙门氏菌病发病率分别下降了66%和63%。大多数沙门氏菌病病例（72%）与旅行相关，其中27%在东南亚感染。最常见的血清型是鼠伤寒沙门氏菌和肠炎沙门氏菌（国内病例的38%和19%，与旅行相关病例的7%和39%）。在2010 - 2022年期间，有31起食源性疫情报告沙门氏菌为病因。其中14起在食品层面确定了源头，12个源头来自国外。本研究结果表明，全国沙门氏菌控制计划可能预防了芬兰国内的人类感染。
