Introduction

Salmonella enterica is a significant foodborne pathogen yet its epidemiology within Ghana remains poorly documented due to limited surveillance. This study aimed to evaluate the prevalence, serotypes, and resistance profiles in asymptomatic food animals and meat products across the Northern regions of Ghana.

Methods

Using purposive sampling, 50 poultry caeca (33 farms), 50 bovine meat samples (26 slaughterhouses), and 28 pooled tilapia kidney/intestine samples (11 farms), were collected in December. These samples were screened using standard culture-based bacteriological techniques. Confirmed Isolates underwent whole-genome sequencing (WGS)  on the illumina platform at the Noguchi Memorial Institute for Medical Research . The Salmonella genome assemblies were analysed for serovar and serogroup prediction  using the Salmonella In-Silico Typing Resource (SISTR) and SeroSeq, based on the Kauffmann–White classification.Furthermore,  Pathogenwatch was  utilized for AMR gene detection and plasmid profiles  their phylogenetic distribution were visualized using iTOL.  

Results

Salmonella spp. were recovered from 12.5% (16/128) of all samples,. with isolation rates stratified by source as follows: 32.1% (9/28) in tilapia, 8% (4/50) in bovine samples, and 6% (3/50) in poultry.  Regarding environmental prevalence, the occurrence was 81.8%  in tilapia farms, 19.2%in slaughtering facilities, and 6.1% (2/33) in poultry farms. WGS of 11 randomly selected isolates revealed a diversity of seven serotypes: Chester, Colindale, and Schwarzengrund, Meleagridis, Kentucky, and S. I 4:e,h:-. Notably, a bovine isolate recovered from Sheshigu harboured blaTEM-1B and tet(A) genes conferring resistance to beta-lactams and tetracycline antibiotics, respectively, in association with an IncI1-I plasmid replicon. 

Conclusion

Reporting Salmonella serotypes previously undocumented in Ghana, these findings reveal significant AMR-related risks across meat supply chains. This potential threat for food handlers and women underscores the urgent need for integrated One Health genomic surveillance and enhanced safety interventions to mitigate public health risks.
