Abstract
Listeria monocytogenes is a foodborne pathogen, typically associated with contaminated dairy products and deli meats. L. monocytogenes can lead to severe infections in high-risk patient populations; in neonates, listeriosis is rare but carries a high rate of neurological morbidity and mortality. Here a case of neonatal listeriosis, in the newborn of a young Hispanic mother who frequently ate queso fresco (a fresh Mexican cheese), is presented. Pregnant women are commonly counselled to avoid unpasteurised dairy during the pregnancy, but many are unaware that soft cheeses, and other food products, may pose risks for perinatal infection. L. monocytogenes remains a cause of food-related outbreaks and maternal and neonatal sepsis around the world, and healthcare providers should ensure that expectant mothers are carefully counselled regarding potential sources.
