Salmonella remains a major cause of foodborne outbreaks in Europe despite the implementation harmonized control programmes. Outbreak data are observed at public health endpoint and provide picture most important sources human salmonellosis level exposure. To prioritize interventions, it is to keep abreast trends outbreaks. The objective this study was determine main food recent Europe. outbreak from 34 European countries 2015–2019 were obtained Food Safety Authority (EFSA). For source attribution analysis, implicated foods categorized according EFSA's zoonosis catalogue classification scheme. An established probabilistic model applied using information on foods, overall by region serotype. assess significant occurrence, serotype, mixed-effects Poisson models used. Overall, eggs (33 %, 95 % Uncertainty Interval [UI]: 31–36 %), followed pork (7 UI: 6–8 (general) meat products (6 5–8 %). While all regions, second common Northern Western Europe, Eastern Southern Outbreaks caused S. Enteritidis (SE) other known serotypes (other than SE Typhimurium its monophasic variant [STM]) mostly attributed (37 34–41 17 11–25 respectively), whereas STM mainly (34 27–42 there increase number reported between 2015 2019, 5 average per year (Incidence Rate Ratio [IRR]: 1.05, Confidence [CI]: 1.01–1.09). This driven significantly increased particularly those (IRR: 1.15, CI: 1.09–1.22), decreased 2019 0.72, 0.61–0.85; IRR: 0.70, 0.62–0.79, respectively). Regional, temporal serotype-associated differences relative contributions different also observed.
