Tips For Handling Deli Meats During Listeria Outbreak
U.S. health officials are currently investigating a serious listeria outbreak linked to sliced deli meats, which has resulted in two deaths and 28 hospitalizations across 12 states. While a specific food recall has not been issued yet due to the uncertainty about the exact contaminated products, at-risk individuals—such as pregnant women, the elderly, and those with weakened immune systems—are advised to avoid consuming deli meats unless they are thoroughly reheated to a steaming hot temperature. The CDC has noted that the number of cases may be underreported, as those who recover at home are less likely to be tested, which may mean the outbreak could be more widespread than currently known.
Recent findings indicate that most of the infected individuals had consumed deli-sliced meats, particularly turkey, liverwurst, and ham, from various supermarket delis. Genetic analysis of bacterial samples from affected individuals shows a close genetic link, suggesting that deli meats are likely the source of this outbreak. However, the CDC has not yet determined which specific products are responsible.
Listeria infections typically cause symptoms such as fever, muscle aches, and fatigue, and can escalate to more severe symptoms like a stiff neck and confusion. Symptoms may appear from immediately to 10 weeks after consuming contaminated food. Diagnosis is usually made through tests of blood or other bodily fluids. The infection is particularly dangerous for people over 65 and those with weakened immune systems. Among the outbreak victims, ages ranged from 32 to 94, with a median age of 75.
Pregnant women are at increased risk of miscarriage due to listeria, although one pregnant victim in this outbreak did not experience a miscarriage. Intestinal listeriosis, confined to the gut, often does not require antibiotics and can be managed with hydration. However, if the infection spreads beyond the gut, it becomes more severe and often requires antibiotic treatment to prevent complications like blood infections and brain inflammation.
There is currently no evidence that prepackaged deli meats are involved in the outbreak. For those with deli meats in their refrigerators, reheating them to an internal temperature of 165°F (74°C) or until they are steaming hot will eliminate any potential bacteria. This is consistent with the CDC’s general advice for high-risk individuals to either avoid deli meats or ensure they are properly heated before consumption. Past listeria outbreaks have led to recalls of various food products, including cheeses and packaged salads.
