An ongoing outbreak of Salmonella Enteritidis in Île-de-France, France, first identified in November 2024, has resulted in 103 confirmed cases as of February 2025. Most cases (92%) are from the Île-de-France region, with a median age of 23. Among those interviewed, 58% required hospitalization, and four needed intensive care. Epidemiological investigations linked several cases to egg consumption, including contaminated mayonnaise in a restaurant. However, the exact source remains unidentified, especially given the regional confinement of cases despite a dispersed egg supply chain. This is the largest recorded S. Enteritidis outbreak in the region, highlighting the critical need for multidisciplinary collaboration in outbreak response.
