A comprehensive epidemiological report published by the UK Health Security Agency (UKHSA) reveals that laboratory-confirmed cases of non-typhoidal Salmonella in England reached a ten-year high in 2025.
In 2025, national laboratory reports of non-typhoidal Salmonella reached 10,406 cases, a marginal 0.17% increase from the 10,389 cases recorded in 2024. The overall reporting rate stood at 17.8 cases per 100,000 population. Consistent with historic baselines, infections demonstrated strong temperature-dependent variations, with significantly higher case volumes occurring between May and October. September marked the absolute seasonal peak for 2025, accounting for 1,424 reported cases. The overwhelming majority of human infections continue to be driven by two primary serovars, though their individual percentages declined slightly in 2025 as minor serovars expanded:
-Salmonella Enteritidis: Retained its status as the most prevalent strain, representing 3,104 laboratory notifications (3,166 in 2024).
-Salmonella Typhimurium: Remained the second most frequently isolated serovar (including its monophasic variants), logging 1,616 cases (1,698 in 2024). Conversely, the data highlights noticeable increases in several alternative serovars, specifically S. Saintpaul, S. Infantis, S. Java, S. Chester, and S. Bareilly.
Children under the age of 10 represented the single most affected age bracket, accounting for 20.3% of the total caseload with 2,094 confirmed infections.
During 2025, a total of 13 foodborne Salmonella outbreaks were reported to national surveillance networks, encompassing 269 individual cases, 258 laboratory-confirmed infections, and 12 documented hospitalizations. Traceback and epidemiological investigations linked these cluster events to the consumption of varied food matrices, prominently including:
-Shelled eggs
-Poultry meat products
-Dairy items
-Raw onions
