Listeria is especially harmful to people who are pregnant, aged 65 or older, or with weakened immune systems. CDC always recommends people at higher risk for listeriosis avoid eating meats sliced at the deli or heat them to an internal temperature of 165°F or until steaming hot before eating.

Other Boar’s Head Deli Meat Products

Source of the Outbreak
Epidemiologic and laboratory data now show that meats sliced at delis, including Boar’s Head brand liverwurst, are contaminated with Listeria and are making people sick. Testing identified Listeria in an unopened package of Boar’s Head liverwurst collected as part of this investigation, which resulted in a recall. Whole genome sequencing shows this is the same strain making people sick in this outbreak.
Products sold at the deli, especially those sliced or prepared at the deli, can be contaminated with Listeria. Listeria spreads easily among deli equipment, surfaces, hands, and food. Refrigeration does not kill Listeria, but reheating to a high enough temperature before eating will kill any germs that may be on these meats.
What People at Higher Risk Should Do
Listeria is especially harmful if you are pregnant, are aged 65 or older, or have a weakened immune system due to certain medical conditions or treatments. Other people can be infected with Listeria, but they rarely become seriously ill.
If you are pregnant, are aged 65 or older, or have a weakened immune system:
- Do not eat recalled deli meats. Throw them away or contact stores about returns.
- In addition, do not eat any other deli meats you get sliced at deli counters, unless it is reheated to an internal temperature of 165°F or until steaming hot. Let it cool before you eat it.
- Listeria can grow on foods kept in the refrigerator, but it is easily killed by heating food to a high enough temperature.
- Clean your refrigerator, containers and surfaces that may have touched sliced deli meats.
- This is especially important if you purchased any of the recalled deli products.
- Call your healthcare provider right away if you have any of these symptoms:
- People who are not pregnant usually have fever, muscle aches, and tiredness. They may also get a headache, stiff neck, confusion, loss of balance, or seizures.
- Pregnant people usually have fever, muscle aches, and tiredness. However, Listeria can cause pregnancy loss or premature birth. It can also cause serious illness or death in newborns.
What Everyone Should Do
For people who are generally healthy and not at higher risk of serious infection:
- Do not eat recalled meats. Throw them away or contact stores about returns.
- Check your refrigerator for any recalled deli meats and throw them away or return them to the store. Listeria can grow on foods kept in the refrigerator.
- Clean your refrigerator, containers and surfaces that may have touched recalled meats.
What Businesses Should Do
- For delis that received recalled meats:
- Thoroughly clean and sanitize all food and non-food surfaces.
- Throw away any open meats and cheeses in the deli.
- USDA-FSIS is advising delis to not use any opened deli products because recalled products can cross-contaminate other deli meats and cheeses.
- Always follow USDA-FSIS best practices for controlling Listeria contamination in deli areas.
Listeria Symptoms
- Listeria is especially harmful to people who are pregnant, aged 65 or older, or with weakened immune systems. This is because Listeria is more likely to spread beyond their gut to other parts of their body, resulting in a severe condition known as invasive listeriosis.
- For people who are pregnant, Listeria can cause pregnancy loss, premature birth, or a life-threatening infection in their newborn.
- For people who are 65 years or older or who have a weakened immune system, Listeria often results in hospitalization and sometimes death.
- Symptoms usually start within 2 weeks after eating food contaminated with Listeria but may start as early as the same day or as late as 10 weeks after.
- Pregnant people usually have fever, muscle aches, and tiredness.
- People who are not pregnant usually have fever, muscle aches, and tiredness. They may also get a headache, stiff neck, confusion, loss of balance, or seizures.
