Bacteria and viruses were analysed in the upper respiratory tract of symptomatic pig farmers and their domestic pigs. Eighty six human nasal and 495 (50 pools) porcine snout swabs were collected in Schleswig‐Holstein, Germany. Staphylococcus (S.) aureus (62.8%, 54/86), human rhino‐ and coronaviruses (HRV, 29.1%, 25/86; HCoV, 16.3%, 14/86) were frequently detected in humans, while Haemophilus parasuis (90.0%, 45/50), Mycoplasma hyorhinis (78.6%, 11/14), Enterovirus G (EV‐G, 56.0%, 28/50) and S. aureus (36.0%, 18/50), respectively, were highly prevalent in pigs. The detection of S. aureus in human follow‐up samples indicates a carrier status. The methicillin‐resistant phenotype (MRSA) was identified in 33.3% (18/54) of nasal swabs and in one of 18 (5.6%) pooled snout swabs that were tested positive for S. aureus . Strains were indicative of the livestock‐associated clonal complex CC398, with t011 being the most common staphylococcal protein A type. Enterobacterales and non‐fermenters were frequently isolated from swabs. Their detection in follow‐up samples suggests a carrier status. All were classified as being non‐multiresistant. There was no example for cross‐species transmission of viruses. In contrast, transmission of S. aureus through occupational contact to pigs seems possible. The study contributes to the ‘One Health’ approach.
