A: Antibiotic Footprint includes antibiotic use in agriculture because most of the antibiotics fed to animals are excreted un-metabolized, then enter sewage systems and water sources, thereby fostering antibiotic-resistant bacteria in the environment (
AMR review, 2015). We can reduce the spread of antimicrobial resistance by reducing the antibiotic use in agriculture. Therefore, antibiotic use in agriculture is included in the Antibiotic Footprint.
