The Centers for Disease Control (CDC) has posted an investigation notice on the agency’s website regarding an outbreak of Listeria linked to consumption of sliced deli meats. Listeria is a bacterium that can cause serious and sometimes fatal infections, particularly in vulnerable populations such as young children, pregnant women, the elderly, and individuals with compromised immune systems.
Background
A significant number of individuals affected by this outbreak have reported consuming deli-sliced meats.
As of July 19, 2024, health officials have identified 28 cases of Listeria infection linked to this outbreak across 12 states. The infections were detected between May 29 and July 5, 2024. All 28 individuals required hospitalization, including one pregnant person who recovered while maintaining their pregnancy. There have been two deaths from the outbreak so far – one in Illinois and another in New Jersey.
These numbers likely underrepresent the true scale of the outbreak. Many people who contract a foodborne illness may recover without seeking medical attention or getting tested, meaning their cases go unreported. Additionally, there’s often a delay in reporting and connecting new cases to an ongoing outbreak, typically taking 3 to 4 weeks. This means more recent infections may not yet be included in the current count.
The geographic spread of the outbreak may also be wider than currently known. While 12 states have confirmed cases, it’s possible that infections have occurred in other states but haven’t been identified or reported yet.
States with reported cases currently include MN, WI, MO, IL, GA, NC, VA, MD, PA, NJ, MA, and NY.
Product Details
The CDC and U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) along with state and local health officials are currently gathering information to pinpoint the source of the outbreak and which specific products may be contaminated.
Consumer Action
Consumers should be cautious when handling and consuming deli meats, especially those sliced at the counter since they are susceptible to Listeria contamination. Listeria is highly transmissible within the deli environment, easily spreading across equipment, surfaces, hands, and food items.
Proper food safety practices, including adequate reheating of deli meats to an internal temperature of 165°F can help reduce the risk of Listeria infection. The food should be cooled before eating.
Consumers should clean and sanitize their refrigerator or any surfaces that have touched the sliced deli meats.
Health Risks
Listeriosis is an infection that causes fever, gastrointestinal symptoms, and muscle aches and is caused by the consumption of food contaminated by bacterium Listeria monocytogenes. Unlike other strains of bacteria, listeria multiplies in foods stored in the refrigerator. Pasteurization and thorough cooking are the most effective methods of killing the bacteria and preventing infection.
Consumers should call their healthcare providers immediately if they are experiencing symptoms of Listeriosis.
Food Poisoning News has reported on several recalls this summer linked to Listeria contamination including cucumbers and plant-based beverages.
Commenting on this story, one national Listeria lawyer said, “The scale of this Listeria outbreak is not yet known and could possibly grow. I urge all consumers, but especially those more susceptible to Listeria infection, take special care when consuming deli meats and follow recommended food safety practices.”
