Deli Meats Sold Nationwide Linked to Listeria Outbreak—Here’s What You Need to Know

Before picking up your cold cuts from the deli, take caution. According to an ongoing investigation by the Centers for Disease Control and Prevention (CDC), an active nationwide outbreak of listeria has been linked to sliced deli meats.

The CDC states that "products sold at the deli, especially those sliced or prepared at the deli, can be contaminated with listeria," as it can spread easily among deli equipment, surfaces, hands, and food. While investigators collect information regarding which specific meats caused the illness, consumers are urged to act cautiously.

Consumers, especially those at higher risk, should avoid eating sliced meats purchased from the deli counter unless they are heated to an internal temperature of 165 degrees Fahrenheit or until steaming hot. Although listeria can grow on refrigerated foods, it can be killed if food is heated to a high enough temperature. Additionally, consumers should clean their refrigerators, containers, and surfaces that may have touched sliced deli meats.

So far, 28 illnesses have been reported across 12 states in the U.S., including Georgia, Illinois, Maryland, Massachusetts, Minnesota, Missouri, New Jersey, New York, North Carolina, Pennsylvania, Virginia, and Wisconsin. However, the CDC notes that this outbreak may not be limited to the states with known illnesses, and the true number of sick people is likely higher than the number reported.

Consuming products contaminated with listeria could result in listeriosis, an infection that can cause serious illness in older adults, people with weakened immune systems, pregnant people, and newborns. Symptoms of listeriosis usually start within two weeks after eating contaminated food but may start as early as the same day or as late as 10 weeks after, per the CDC.

Those with specific questions about potential illness should contact their healthcare provider or visit the CDC's frequently asked questions page about listeria.
