Listeria infections: The unexpected risks in everyday foods
Year: 2025
Type: article
Abstract: Listeria monocytogenes remains a major public health concern due to its ability to survive in diverse environments, including under refrigerated conditions, and cause severe illness in vulnerable populations. In July 2024, a Listeria outbreak linked to deli-sliced meats in the United States resulted in 61 confirmed cases, 60 hospitalizations, and 10 deaths across 19 states, underscoring persistent challenges in food safety. Historical outbreaks involving dairy, produce, and processed meats highlight the complexity of contamination routes and the importance of comprehensive preventive measures. As an intracellular pathogen, Listeria requires prompt diagnosis and targeted antibiotic therapy, typically involving ampicillin and gentamicin. Control efforts are complicated by the bacterium’s propensity for biofilm formation and its resilience under cold storage. Advances in sanitation protocols, whole-genome sequencing, and public health initiatives are key to reducing the incidence of listeriosis. Nevertheless, continued outbreaks emphasize the need for rigorous food safety practices, high-risk population awareness, and ongoing surveillance.
