Antimicrobials are widely used in livestock production to maintain health and promote growth, contributing to the spread of drug-resistant pathogens in both livestock and humans. CDDEP developed the first global map of antibiotic consumption in livestock (Van Boeckel et al., PNAS) and conservatively estimated that 63,151 tons were consumed in 2010. According to these estimates, China, the United States, Brazil, Germany, and India are the largest consumers, collectively consuming about half of the global total. Based on current trajectories, CDDEP estimated that total consumption by livestock would increase by 67% by 2030, nearly doubling in Brazil, Russia, India, China, and South Africa. The main drivers will be growth in consumer demand for meat and other livestock products in middle-income countries and a consequent shift toward large-scale farming operations where antimicrobials are routinely used. Recent country-level estimates and projections through 2030 are included in ResistanceMap.
