Listeria Symptoms
Listeria is especially harmful to people who are pregnant, aged 65 or older, or have 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.

Source of the Outbreak
Many people in this outbreak are reporting eating meats that they had sliced at deli counters. Investigators are collecting information to determine the specific products that may be contaminated. 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 meats you get sliced at any deli counter, 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.
- 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.
- Do not eat meats you get sliced at any deli counter, unless it is reheated to an internal temperature of 165°F or until steaming hot. Let it cool before you eat it.
