FSIS NARMS Multi-Year Report – 2014-2019

  16 February 2023

This FSIS NARMS Multi-Year Report evaluates trends in Salmonella serotypes and antimicrobial resistance (AMR) in certain food animal species and products sampled from 2014 through 2019 as part of FSIS NARMS sampling. This is the first multi-year Salmonella trend analysis of NARMS data to focus on samples collected by FSIS.

Samples analyzed included cecal (intestinal content) samples from food-producing animals at slaughter and product samples tested as part of Pathogen Reduction/Hazard Analysis Critical Control Point (PR/HACCP) sampling (henceforth stated as product sampling). Salmonella isolates were analyzed by serotyping and antimicrobial susceptibility testing (AST) to evaluate differences in sample source and slaughter class (chicken, turkey, cattle, and swine).

This report is intended to highlight certain data trends to identify emerging areas of concern in antimicrobial resistance and Salmonella serotypes of public health concern. This report is focused on Salmonella findings only.
