Salmonella sp. Tied to Multistate Outbreak Isolated from Wastewater, United States, 2022

Emerg Infect Dis. 2024 Dec;30(12):2695-2697. doi: 10.3201/eid3012.240443.

Abstract

We isolated Salmonella enterica serovar Senftenberg in raw wastewater from 2 Pennsylvania wastewater treatment facilities during June 2022. Whole genome sequencing revealed 4 isolates separated by <4 single nucleotide polymorphisms from S. enterica Senftenberg in a cluster from the 2022 nationwide outbreak linked to contaminated peanut butter.

Keywords: Salmonella enterica; Senftenberg; United States; bacteria; outbreak; wastewater; wastewater surveillance.
