Listeria Outbreak Linked to Deli Meats: CDC Investigation Update
The Centers for Disease Control and Prevention (CDC) reports that 59 people across 19 states have been infected with the outbreak strain of Listeria monocytogenes linked to deli-sliced meats. As of September 25, all 59 individuals have required hospitalization, and 10 deaths have been confirmed. While the rate of new illness reports has begun to decline, health officials continue to monitor the situation due to the long incubation period of the bacteria.
Did You Know? Symptoms of severe listeriosis can appear as early as the same day an individual consumes contaminated food, but in some cases, the onset of illness may be delayed for up to 70 days.
Current status of the outbreak
Since the last update provided on August 28, the CDC has documented two additional illnesses and one new death, which occurred in New York. The total case count now stands at 59, with all affected individuals requiring medical care in a hospital setting. Because the incubation period for Listeria can last up to 10 weeks, the agency indicates it will continue to collect data and track potential new cases, though it plans to reduce the frequency of its public updates.
Risk factors and symptoms
Invasive listeriosis occurs when bacteria move beyond the gastrointestinal tract to other areas of the body. According to the CDC, symptoms for individuals who are not pregnant include stiff neck, confusion, loss of balance, headaches, fever, and muscle aches. For pregnant individuals, the infection is often characterized by fatigue and fever, but it carries significant risks including miscarriage, stillbirth, premature delivery, or life-threatening illness for the newborn.
Safety measures for consumers and businesses
Consumers are advised to avoid eating any recalled deli meats, some of which may have “sell by” dates extending into October 2024. Individuals at higher risk—including those over age 65, those with weakened immune systems, and pregnant people—are advised to avoid meats sliced at deli counters entirely unless the product is heated to an internal temperature of 165°F or until steaming hot. Businesses that received recalled products are instructed to sanitize surfaces and discard any opened deli meats or cheeses.
Expert Insight: The extended incubation window of Listeria means that public health agencies must remain vigilant long after initial product recalls are issued. Because the bacteria can survive in cold environments like refrigerators, the emphasis on cleaning surfaces and containers is a critical step in preventing secondary contamination in the home.
