A recent listeria outbreak tied to deli meats has resulted in two fatalities and hospitalized 28 people across several states, according to the Centers for Disease Control and Prevention (CDC). The outbreak has spanned multiple months, with illnesses reported from late May to early July 2024.

The CDC’s investigation revealed that the outbreak is linked to meats sliced at deli counters. The first case was reported in late May, and the most recent case occurred on July 5. The two deaths were reported in Illinois and New Jersey. Other states affected include New York (7 cases), Maryland (6 cases), Georgia, Massachusetts, Missouri, New Jersey, and Virginia (2 cases each), and Illinois, Minnesota, North Carolina, Pennsylvania, and Wisconsin (1 case each).

While the exact source of the contamination remains unclear, most of the sick individuals reported eating turkey, liverwurst, or ham from various deli counters. The bacteria, Listeria monocytogenes, can survive refrigeration but is killed by heat. It can spread easily through deli equipment, surfaces, and hands, making delis a common source of outbreaks.

The CDC advises people, especially those at higher risk such as pregnant women, older adults, and individuals with weakened immune systems, to avoid consuming deli meats unless they are reheated to an internal temperature of 165°F or until steaming hot. Consumers are also encouraged to clean their refrigerators and any containers or surfaces that may have come into contact with deli meats to prevent further spread.

Listeriosis, caused by Listeria bacteria, is the third leading cause of death from foodborne illness in the United States. Symptoms typically include fever, muscle aches, and fatigue, and can progress to more severe conditions like meningitis or sepsis. Pregnant individuals may experience pregnancy loss or premature birth. Symptoms can appear within two weeks of consuming contaminated food but may also occur as early as one day or as late as 70 days.

Health officials are conducting interviews to determine the specific products or delis that may be contaminated. The CDC has not yet issued any recalls but continues to work with local public health officials to identify the source of the outbreak. Consumers who develop symptoms of listeriosis should seek medical attention immediately and cooperate with public health officials to track the source of their infection.
