Campylobacter jejuni has a deceptively simple appearance: a small, comma-shaped, microaerophilic Gram-negative bacterium, unremarkable under the microscope. Yet this organism has proven extraordinarily difficult to control, extraordinarily successful as a human pathogen, and extraordinarily instructive about the complex interplay between food production systems, human behavior, microbial ecology, and public health infrastructure. This book is, in a sense, an extended investigation into how such a small organism can cause such a large problem.
The book is organized into five thematic parts, each addressing a distinct but interconnected dimension of the Campylobacter challenge. Part I covers the microbiology and pathogenesis of C. jejuni — the biology that determines how the organism survives in the environment, colonizes its hosts, and causes disease in humans. Part II examines the epidemiology of campylobacteriosis, including its global distribution, risk factors, seasonal patterns, and the molecular epidemiological methods that have transformed our understanding of transmission dynamics. Part III addresses the poultry production interface — the primary pathway through which C. jejuni reaches human populations — with detailed attention to colonization dynamics, biosecurity, intervention strategies, and the regulatory frameworks governing poultry processing. Part IV is dedicated to antimicrobial resistance — the most urgent current concern in Campylobacter public health — covering resistance mechanisms, global trends, drivers of resistance acquisition and spread, and policy responses. Part V treats surveillance, risk assessment, and control strategy design from an integrative perspective, bringing together the scientific insights of preceding chapters into frameworks for evidence-based decision-making.
Throughout the book, we have sought to integrate scientific rigor with practical relevance. Case studies, data tables, worked examples, and regulatory context are woven into the conceptual content. Where scientific evidence is uncertain or contested, we have aimed to represent the debate faithfully rather than obscuring it with false certainty. Food safety science is a discipline that must act under uncertainty, and clear-eyed acknowledgment of what we do not know is as important as confident statement of what we do.
