We conducted a cross-sectional study to determine the prevalence of Salmonella serovars in egg-laying hens and broilers at the farm level and their susceptibility to antimicrobials commonly used in the poultry industry in Ghana. Sampling of faeces by a sock method (n = 75), dust (n = 75), feed (n = 10) and drinking water (n = 10) was performed at 75 commercial egg-laying and broiler farms in two regions of Ghana and skin neck (n = 30) at a local slaughterhouse from broilers representing different flocks. Salmonella was detected in 94/200 (47{\%}) samples with an overall flock prevalence of 44·0{\%}. Sixteen different serovars were identified with S. Kentucky (18·1{\%}), S. Nima (12·8{\%}), S. Muenster (10·6{\%}), S. Enteritidis (10·6{\%}) and S. Virchow (9·6 {\%}) the most prevalent types. The predominant phage type of S. Enteritidis was PT1. All strains were susceptible to cefotaxime, ceftazidime and cefoxitin. Fifty-seven (60·6{\%}) strains were resistant to one or more of the remaining nine antimicrobials tested by disk diffusion, of which 23 (40·4{\%}) showed multi-resistance (resistance to ⩾3 classes of antimicrobials). Of the resistant strains (n = 57), the most significant were to nalidixic acid (89·5{\%}), tetracycline (80·7{\%}), ciprofloxacin (64·9{\%}), sulfamethazole (42·1{\%}), trimethoprim (29·8{\%}) and ampicillin (26·3{\%}).
