A multistate outbreak of Listeria monocytogenes infections linked to deli meats continues to be investigated by the Centers for Disease Control and Prevention (CDC), with , marking the latest update. While the rate of new illnesses appears to be slowing, the outbreak has already resulted in significant illness and loss of life, underscoring the risks associated with consuming potentially contaminated ready-to-eat meats.
As of the latest report, a total of 59 people across 19 states have been infected with the outbreak strain of Listeria. All 59 individuals required hospitalization, and tragically, 10 deaths have been reported. Deaths have occurred in Illinois, New Jersey, New York (two deaths), Virginia, Florida, Tennessee, New Mexico, and South Carolina (two deaths). The CDC notes that while new illness reports are decreasing, it can take up to 10 weeks for symptoms to develop, and monitoring will continue for some time to capture any delayed cases.
Understanding Listeriosis
Listeria monocytogenes is a bacterium that can cause a serious infection called listeriosis. While many people experience mild symptoms like fever, muscle aches, and fatigue, the infection can be severe, particularly for certain populations. The CDC highlights several groups at higher risk, including pregnant individuals, adults aged 65 and older, and those with weakened immune systems.
The consequences of listeriosis can be particularly devastating for pregnant people. Infection during pregnancy can lead to miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn. In non-pregnant individuals, severe symptoms can include headache, stiff neck, confusion, loss of balance, and convulsions, in addition to the initial flu-like symptoms.
The Outbreak and Recalled Products
The current outbreak has been linked to meats sliced at deli counters, with investigations pointing to products from Boar’s Head Provisions Co. The company has issued recalls of various ready-to-eat meat and poultry products produced at its Jarratt, Virginia facility. Consumers are strongly advised not to consume recalled deli meats and are encouraged to either discard them or return them to the place of purchase.
The recalled products may have “sell by” dates extending into . Consumers should check product labels for the USDA mark of inspection, looking for “EST. 12612” or “P-12612”.
Preventing Listeriosis: Steps to Take
The CDC offers several recommendations to help prevent listeriosis, particularly for those at higher risk:
- Avoid Deli-Sliced Meats: Individuals at increased risk should avoid consuming meats sliced at deli counters unless they are heated to an internal temperature of 165°F (74°C) or until steaming hot immediately before serving.
- Thorough Cleaning: We see crucial to thoroughly clean refrigerators, containers, and surfaces that may have come into contact with sliced deli meats. Listeria is a hardy bacterium that can survive even at refrigerated temperatures.
- Seek Medical Attention: Anyone experiencing symptoms of listeriosis, especially after consuming deli meats, should promptly contact their healthcare provider.
- Business Precautions: Businesses handling recalled meats should take extra precautions, including cleaning and sanitizing deli areas and discarding any opened sliced meats and cheeses. Following USDA-FSIS best practices for controlling Listeria contamination is essential.
Listeria’s ability to thrive in refrigerated environments and its long incubation period – symptoms can appear anywhere from the same day as exposure to 70 days later – make prevention particularly challenging. The CDC emphasizes the importance of diligent food safety practices and awareness of potential risks.
What to Expect Moving Forward
The CDC continues to analyze data from the outbreak, including epidemiologic, laboratory, and traceback information, to pinpoint the source of the contamination and prevent further illnesses. While the number of new cases appears to be slowing, ongoing monitoring is crucial. The agency will continue to provide updates as new information becomes available.
This outbreak serves as a critical reminder of the importance of food safety and the potential risks associated with ready-to-eat meats. Consumers, particularly those in high-risk groups, should remain vigilant and follow the CDC’s recommendations to protect themselves from listeriosis.
