The CDC published in Morbidity and Mortality Weekly Report (MMWR), May 15, 2025, MMWR Weekly 74(17);293–295 on Multistate outbreak of Salmonella enterica I 4:I:- infection linked to Charcuterie meats in the US 2023-2024. During December 2023–March 2024, CDC and public health partners in 33 states investigated an outbreak of Salmonella enterica I 4:I:- infection linked to contaminated charcuterie-style meats. Early usage of purchase records identified a common charcuterie product from one company and enabled a swift recall. On December 19, 2023, CDC’s PulseNet identified a cluster of 13 Salmonella enterica I 4:I:- infections in five states that were found to be highly related by WGS, indicating a possible outbreak. Among 68 patients from 27 affected states, 50 (74%) reported consuming charcuterie-style meats before illness onset. The report describes the largest US infectious outbreak associated with charcuterie-style meats since 2010. Consumer purchase records were successfully used for hypothesis generation in this outbreak investigation and provided a critical foundation for traceback activities. Coupled with patient interview information, the use of purchase records enabled rapid identification and recall of contaminated products 17 days after the investigation began.
