Prevalence and antibiotic resistance of Salmonella in organic and non-organic chickens on the Eastern Shore of Maryland, USA.

ABSTRACT:

Introduction

Salmonella infections have been intensely increasing and becoming a universal public health crisis. This study investigated the prevalence of Salmonella in organic and non-organic chickens and the antimicrobial resistance profiles and virulence genes (invA, pagC, and spvC) in recovered Salmonella isolates.

Methods

Whole chicken carcasses [organic (n = 240) and non-organic (n = 240)] were obtained monthly for 1 year (n = 480) from a retail store on the Eastern Shore of Maryland. Salmonella isolation and identification were conducted by following the whole carcass enrichment method recommended by USDA-FSIS. Confirmed Salmonella isolates (organic n = 76; non-organic n = 137)
