For many of us, our encounters with listeria may not go beyond reading the occasional headline about an outbreak from contaminated hot dogs or listening to our doctor advise us to avoid certain foods while pregnant. But as we explore in this episode, the story of Listeria monocytogenes is more complex, scary, and unexpected than you may have imagined. Join us this episode as we trace the dual-natured and sometimes extremely deadly infections this pathogen can cause, examine how the industrial revolution and cattle movements may have altered the landscape of Listeria monocytogenes, and ask why cell biologists are so enamored with this bacterium. One thing’s for sure: this isn’t your typical food-borne pathogen.
