Nineteen Salmonella strains were isolated from 5,907 randomly selected mussel samples during a monitoring programme for the presence of Salmonella in shellfish in Galicia, north-west Spain (2012–16). Serovars, sequence type and antimicrobial resistance genes were determined through genome sequencing. Presence of the mcr-1 gene in one strain belonging to serovar Rissen and ST-469 was identified. The mcr-1 gene had not been isolated previously in environmental Salmonella isolated from mussels in Spain.
