Most Recent Major Listeria Outbreaks
The last large listeria outbreak in the United States linked to a single product occurred in early 2024, with illnesses traced to deli meats and soft cheeses. The outbreak prompted recalls and warnings from the CDC and FDA.
In 2023, several smaller listeria clusters were identified in various states, often connected to imported produce and ready-to-eat foods. These incidents led to targeted recalls and updated handling guidance for retailers and consumers.
Common Sources and Symptoms
Listeria is commonly found in unpasteurized dairy, deli meats, and soft cheeses. Symptoms include fever, muscle aches, nausea, and diarrhea, and can become severe in older adults and pregnant individuals.
Regulatory Response and Prevention
Health agencies investigate outbreaks through traceback, testing, and public alerts. The CDC and FDA provide guidance on safe food handling, including reheating deli items and avoiding high-risk products during pregnancy.
