Listeriosis: What should nurses know?

Listeria infection, or listeriosis, is a foodborne illness caused by the pathogen Listeria monocytogenes. In 2022 through 2024, multiple products, including deli meats, soft cheeses, ice cream, fruits, and vegetables, were recalled for Listeria contamination or outbreaks. Another outbreak from November 2024 through January 2025 associated with ready-to-eat meat and poultry products involved 19 cases, 17 hospitalizations, and 2 deaths in eight states. An outbreak identified in February 2025 linked to frozen supplemental shakes involved 38 cases, 37 hospitalizations, and 12 deaths in 21 states. This article discusses the incidence, transmission, clinical presentation, and diagnosis of listeriosis, as well as considerations for nursing management, including care for high-risk groups.
