Resistomes from oxytetracycline-treated pigs are readily transferred to untreated pen mates.

ABSTRACT: Pork is currently a major part of Danish food export and is also a key dietary source of protein across the world. Industrial pork production, however, comes with high antibiotic usage in many countries, including Denmark. This has created consumer demand for meat Raised Without Antibiotics (RWA). Previous work has demonstrated that levels of antibiotic resistance genes (ARGs) are indeed increased in antibiotically treated animals, but also suggest that these ARGs are transferred to untreated pen-mates. In a Danish commercial farm, we studied four groups of physically separated pigs: one group of only antibiotic treated pigs (n = 20), one group of only untreated pigs (n = 30 total, n = 15 analysed), and one group combining treated (n = 15) and untreated pigs (n = 15). These groups were fol
