Increased antibiotic use is a matter of concern as antibiotic resistance is considered to be a serious threat to human and animal welfare in the future, and growing levels of antibiotics or antibiotic-resistant bacteria in the environment could increase the numbers of drug-resistant infections in both.[10] Bacterial diseases are a leading cause of death and a future without effective antibiotics would fundamentally change the way modern human as well as veterinary medicine is practised.[10][11][3] However, legislation and other curbs on antibiotic use in farm animals are now being introduced across the globe.[13][14][15] In 2017, the World Health Organization strongly suggested reducing antibiotic use in animals used in the food industry.[16]
