Human salmonellosis cases in Slovenia declined by approximately 23% in 2025 compared with the previous year, according to the annual epidemiological surveillance report published by the National Institute of Public Health (NIJZ). Despite this decrease, health officials emphasize that Salmonella remains an important foodborne pathogen and a cause of localized outbreaks.
Slovenia recorded 340 confirmed human infections in 2025, corresponding to an incidence of 16.0 cases per 100,000 population, down from 439 cases in 2024. The 2025 figure was close to the national five-year average of 324 cases. A total of 162 patients required hospitalization.
Among the 340 primary isolates characterized, Salmonella Enteritidis was the predominant serotype, accounting for 35.6% of cases (121 isolates). It was followed by Salmonella Typhimurium (18.8%; 64 isolates) and Salmonella Coeln (10.9%; 37 isolates).
Authorities investigated three distinct salmonellosis outbreaks during the year. In sporadic cases, patients most frequently identified inadequately cooked poultry and eggs, as well as grilled meats, as suspected sources of infection. Travel-associated exposures accounted for 28 cases, predominantly linked to trips to Croatia and Turkey. Additionally, Salmonella was identified as one of several co-pathogens during a major waterborne outbreak at a commercial complex in Ljubljana.
