Non-enterica subspecies of Salmonella enterica are associated with cold-blood animals. We report the complete genomes of six S. enterica strains (one S. enterica subsp. arizonae strain, four S. enterica subsp. salamae strains, and one S. enterica subsp. diarizonae strain) isolated from Spanish poultry houses. This will increase our knowledge of these non-enterica subspecies.
