Centralized industrialization of pork in Europe and America contributes to the global spread of *Salmonella enterica*

H. Li, Y. Wu, et al.

This captivating study explores the effects of intensive farming and global transportation on the evolution of *Salmonella enterica*, a significant zoonotic pathogen. By examining over 9,000 genomes from pig-associated populations, the authors unveil the strong links between the global pork trade and these pathogens’ emergence. Discover how modern pig agriculture plays a pivotal role in antimicrobial resistance and the worldwide spread of salmonella.

Abstract
This study investigated the impact of intensive farming and global transportation on the evolution of *Salmonella enterica*, a zoonotic pathogen. Analyzing over 9,000 genomes from nine pig-enriched *S. enterica* populations, researchers found strong associations between the transmission of these salmonellae and the global pork trade, particularly from Europe and the United States. The study highlights the role of modern pig agriculture in driving the emergence, population expansions, antimicrobial resistance acquisition, and global dissemination of pig-enriched *Salmonella* populations.
