Isolation of Antibiotic-Resistant Bacteria from the Air Plume Downwindof a Swine Confined or Concentrated Animal Feeding Operation

Abstract

Bacterial concentrations with multiple antibiotic resistances or multidrug resistance were recovered inside and outside to (at least) 150 m downwind of this facility at higher percentages than upwind. Bacterial concentrations with multiple antibiotic resistances were found within and downwind of the facility even after subtherapeutic antibiotics were discontinued. This could pose a potential human health effect for those who work within or live in close proximity to these facilities.
