Listeriosis: A Resurfacing Menace

Listeriosis is a rare but potentially deadly foodborne infection. Listeria monocytogenes is a common contaminant of food, and may cause severe disease in pregnant women, fetuses, neonates, the elderly, and those who are immunocompromised by medical conditions or treatments. Delay in treatment is an independent risk factor for neurologic sequela of L monocytogenes infection. A review of the literature, pathophysiology, epidemiology, clinical presentation, prevention, diagnosis, and treatment options is presented. The role of the primary care provider in prevention, patient education, and clinical management is reviewed.
