Few bacteria have shaped the modern food industry as profoundly as Listeria monocytogenes. It's invisible to the eye, resistant to cold, and capable of surviving where most microbes die - in clean, refrigerated spaces. Understanding Listeria pulls back the curtain on how this stubborn organism continues to challenge science, industry, and public health, even in an age of advanced technology and global regulation.Through clear storytelling and deeply researched insight, this book connects the dots between the science of infection, the real human cost of outbreaks, and the systemic weaknesses that allow Listeria to slip into foods we trust - from deli meats and soft cheeses to ready-to-eat salads and pre-cooked meals.You'll learn: How Listeria monocytogenes survives in cold, sanitized environments where few others can.Why certain groups - pregnant people, newborns, the elderly, and immunocompromised individuals - face the greatest risk.What investigators uncover when tracing outbreaks from hospital wards to factory drains.How global supply chains and convenience foods create new paths for contamination.What regulators, scientists, and companies are doing - and still failing to do - to keep food safe.The technologies shaping the next generation of prevention: genome sequencing, biosensors, predictive microbiology, and AI-driven surveillance.Written for readers who care about the food they eat - from health professionals and food industry workers to everyday consumers - Understanding Listeria blends science, investigation, and human experience. It exposes how an invisible microbe has become a global teacher on accountability, safety, and the price of neglect.This isn't just a book about bacteria - it's a wake-up call about the systems that feed us, and the future we can build if we decide that "safe enough" is no longer good enough.
