Antimicrobial use in animal production could exceed 100,000 tons a year by 2030. Chronic use of growth-promoting antimicrobials in farming has selected for resistant bacteria that have spread into humans. Facing the reluctance of the food and veterinary industries to report on antimicrobial sales, Van Boeckel et al. used statistical models to map and project global antimicrobial consumption. By far the biggest current and future consumer is China, followed by the United States, but Brazil, India, and Mexico also are or soon will be major users, along with other transitional countries seeking to intensify animal production for their increasingly affluent societies who are demanding more meat to eat.
