Multistate Listeria Outbreak Linked to Boars Head Deli Meats Remains Under Investigation
A multistate outbreak of Listeria monocytogenes infections has been traced to deli meats, including Boar’s Head brand liverwurst, prompting significant public health measures. The CDC and other health authorities are actively investigating the outbreak, which has affected 43 people across 13 states, with three confirmed deaths. At least one of the wrongful death cases is being litigated by the national listeria lawyers at Ron Simon & Associates.
As of August 8, 2024, there have been nine new reported cases since the last update on July 31. All affected individuals have been hospitalized, including one pregnant woman who remains pregnant after recovery. The outbreak’s true extent may be greater than reported due to undiagnosed cases and reporting delays.
Investigation Findings
Key findings in the investigation include:
- The Maryland Department of Health and Baltimore City Health Department identified Listeria monocytogenes in an unopened Boar’s Head liverwurst product from a retail store.
- The New York State Food Laboratory also found Listeria monocytogenes in previously collected unopened Boar’s Head liverwurst samples. Whole Genome Sequencing (WGS) confirmed these samples contain the same strain responsible for the outbreak.
USDA-FSIS has conducted traceback efforts to identify producers linked to the contaminated deli meats.
Understanding Listeria
Listeria monocytogenes, the pathogen spread in the Boar’s Head Liverwurst made at the Jarratt facility, is a bacterium that can cause a serious infection known as listeriosis. It is commonly found in soil, water, and raw milk, and can also contaminate various foods, particularly ready-to-eat deli meats and unpasteurized dairy products. Unlike many other bacteria, Listeria can grow at refrigerator temperatures, which makes it a particular concern for foods stored at home and in commercial settings.
Symptoms of listeriosis include fever, muscle aches, and gastrointestinal symptoms such as nausea and diarrhea. In severe cases, it can lead to meningitis or septicemia, and is particularly dangerous for pregnant women, newborns, older adults, and those with weakened immune systems. Pregnant women can experience flu-like symptoms, but the infection can lead to serious complications including miscarriage, stillbirth, or premature birth.
Public Health Recommendations
The CDC advises against consuming recalled deli meat products and recommends that individuals who are pregnant, aged 65 or older, or have weakened immune systems avoid eating deli meats unless they are thoroughly heated. These measures are crucial to preventing further infections and protecting at-risk populations.
Efforts are ongoing to identify and address the source of the contamination to prevent future outbreaks. The public is urged to stay informed about food recalls and practice safe food handling to reduce the risk of listeriosis.
