Libro

Food safety continues to be challenged by adaptable foodborne pathogens, and Yersinia enterocolitica has emerged as a significant yet often underrecognized threat. This reference provides a concise yet comprehensive overview of its microbiology, pathogenicity, and public health relevance within modern food systems. The book explores the genetic diversity and key virulence mechanisms of Y. enterocolitica, including its ability to invade intestinal cells and evade host immune defenses. Clinical manifestations of yersiniosis, from mild gastroenteritis to more severe complications, are discussed to highlight its medical importance. Particular emphasis is placed on contamination pathways, especially the strong association with pork and pork-derived products. The organism’s psychrotrophic nature—its ability to grow at refrigeration temperatures—poses unique challenges for food storage and safety, particularly in ready-to-eat foods. Modern detection and surveillance methods, including molecular diagnostics and whole genome sequencing, are presented alongside current epidemiological insights. The book also addresses emerging concerns such as antimicrobial resistance. Integrating science with practice, this volume outlines evidence-based prevention and control strategies grounded in HACCP principles, hygiene, and cold chain management. It serves as a practical and scientific guide for improving food safety and protecting public health.
