A listeria outbreak linked to deli meats has resulted in two deaths and at least 28 hospitalizations across various US states, according to the CDC. The health agency has identified deli meat as the source of contamination and is advising people to avoid eating it unless it has been properly heated. Here’s what you need to know about listeria, its symptoms, and prevention.
Details of the Outbreak
The CDC has traced the outbreak to sliced deli meats, which have been linked to the deaths of two individuals—one in Illinois and another in New Jersey. The outbreak has also led to hospitalizations: seven in New York, six in Maryland, and additional cases in Georgia, Massachusetts, Missouri, New Jersey, Virginia, Illinois, Minnesota, North Carolina, Pennsylvania, and Wisconsin.
The CDC warns that the actual number of affected individuals may be higher, as some people recover without medical attention and are not tested for listeria. The agency also notes that recent illnesses might not yet be reported, as it can take weeks to confirm cases.
Link to Deli Meat
The outbreak, which started in May, has been traced back to contaminated deli meats. Of the 18 people interviewed, two reported eating sliced deli meats prior to falling ill. Investigation revealed that the majority had consumed turkey or liverwurst, and tests identified a common strain of bacteria across different grocery store delis.
Listeria is highly contagious and can spread through surfaces, equipment, and food. It is not eliminated by refrigeration, but cooking deli meat to at least 165 degrees F can kill the bacteria. The CDC advises heating deli meats thoroughly before consumption and cooling them down.
What is Listeria?
Listeria, caused by the bacteria L. monocytogenes, is a severe foodborne illness that can be life-threatening. It can be contracted through contaminated food, groundwater, rotting vegetables, and animal feces. Unlike other bacteria, L. monocytogenes can survive and multiply at low temperatures, including in refrigerators and freezers.
Food contaminated with listeria may not show changes in smell, taste, or texture, making it difficult to detect spoilage.
Symptoms of Listeria
Key symptoms of listeria infection include:
- Fever
- Chills
- Headache
- Upset stomach
- Diarrhea
- Nausea and vomiting
- Muscle aches
- Loss of balance
- Convulsions or uncontrolled muscle contractions
A severe listeriosis infection can lead to complications such as sepsis, meningitis, or encephalitis, which can be fatal.
