Outlook (Prognosis) Listeriosis in a fetus or infant is often fatal. Healthy older children and adults are more likely to survive. The illness is less serious if it only affects the gastrointestinal system. Brain or spinal infections have worse outcomes. Possible Complications Infants who survive listeriosis may have long-term brain and nervous system (neurologic) damage and delayed development. When to Contact a Medical Professional Call your health care provider if you or your child develops symptoms of listeriosis. Prevention Foreign food products, such as nonpasteurized soft cheeses, have also led to outbreaks of listeriosis. Always cook food thoroughly.Wash your hands thoroughly after touching pets, farm animals, and handling animal feces.Pregnant women may want to visit the Centers for Disease Control and Prevention (CDC) website for information on food precautions: www.cdc.gov/listeria/prevention.html.Open ReferencesReferencesJohnson JE, Mylonakis E.
