Prevalence, Concentration, and Antimicrobial Resistance Profiles of Salmonella Isolated from Florida Poultry Litter

What is it about?

The use of untreated animal manures, or biological soil amendments of animal origin (BSAAO), to amend agricultural soils holds a risk of contamination from foodborne pathogens, such as Salmonella. This study was conducted to determine the prevalence, concentration, serotypes, and antimicrobial resistance (AMR) profiles of Salmonella in poultry litter from Florida farms. Serovars Typhimurium, Kentucky, Enteritidis, and Mbandaka were most common. Antimicrobial resistance to tetracycline, sulfisoxazole, and streptomycin was seen. Multidrug-resistant Salmonella isolates were not observed. The findings of this study fill a knowledge gap by presenting Salmonella prevalence, concentration, and AMR data for a region of the U.S. that has not been described in previously published works. The absence of multi-drug resistant Salmonella isolates in litter samples is encouraging for farmers and stakeholders in this region.
