Abstract

A Salmonella enterica serovar Abony outbreak occurred during January-April 2024 in Chile. Genomic evidence indicated that the outbreak strain was a clone of reference strain WDCM 00029, which is routinely used in microbiological quality control tests. When rare or unreported serovars cause human infections, clinicians and health authorities should request strain characterization. © 2025 Centers for Disease Control and Prevention (CDC).
