摘    要：

Antimicrobial resistance is a major global public health challenge, and the widespread use of antimicrobials in the livestock sector is one of its primary drivers. Based on a global supply chain model, this study quantifies and analyzes the antimicrobial footprint of livestock production and its global flows through trade chains from 2010 to 2020. The results show that the global antimicrobial footprint peaked at 118.6 kilotonnes in 2013 and declined to 84.0 kilotonnes by 2020. China and the United States were the largest contributors, together accounting for nearly 60% of the global total. The per capita antimicrobial footprint decreased from 15.6 grams to 11.6 grams over the study period. Although most antimicrobial use remained embodied in domestic production, the share embodied in international trade increased from 16% to 20%, indicating substantial global spillover effects. Notably, Brazil surpassed China in 2020 to become the largest exporter of antimicrobials embodied in trade. Non-food products (such as apparel, services, and manufacturing goods) accounted for approximately half of the antimicrobial footprint embodied in trade. The decline in trade-related antimicrobial use is closely associated with stricter policies and reduced use intensity, particularly in China. This study reveals the complex linkages between antimicrobial use and global trade and provides empirical evidence to support antimicrobial governance at both global and national levels, thereby contributing to the sustainable development of the livestock sector.
