There is a long-term cross-border outbreak of Salmonella Strathcona ST2559 in the EU/EEA, with 437 confirmed cases in 17 EU/EEA countries from 2023 to 30 September 2025[1]. Italy (123), Germany (113) and Austria (76) have reported the highest number of cases[4]. Investigations in Austria (2023) and Italy (2024) confirmed that the vehicle of infection was small tomatoes from the Sicilian region, which was also found in the historical outbreak in Denmark in 2011[3]. In some cases, Salmonella S. Strathcona has been detected in irrigation water samples and on tomato-producing farms in Sicily, suggesting possible environmental contamination of crops[2]. Among the confirmed cases, there are also cases associated with travel; Italy was the most frequent country visited among travelers[4]. Positive findings in poultry and eggs have also been reported on a breeding farm owned by a person who became ill in November 2023[1]. ECDC considers adequate surveillance, epidemiological investigation and cooperation between health and food authorities to be important in the future management of this outbreak[1].
