There is a long-term cross-border outbreak of Salmonella Strathcona ST2559 associated with tomato consumption in the European Union/European Economic Area (EU/EEA) and the United Kingdom.[1][3][4] From 2023 to 30 September 2025, 437 confirmed cases have been identified in 17 EU/EEA countries, including 205 cases since the first assessment on 12 November 2024.[3][4] The highest number of cases have been reported in Germany (113), Italy (123), and Austria (76).[Cases have also been reported in the UK (73), Canada (10) and the USA (24).4[4] This is a re-emergence of S. Strathcona strain ST2559, which previously caused outbreaks in 2011 and 2020.3 Investigations in Austria (2023) and Italy (2024) confirmed small tomatoes from Sicily as the source of the outbreak.[3] In September 2025, the European Commission commissioned ECDC and EFSA to carry out an assessment due to the ongoing risk[3] Further investigations, including genome sequencing, are ongoing in some countries[2].
