.As of August 8, a total of 43 people infected with the outbreak strain of Listeria have been reported from 13 states, Georgia (2), Illinois (1), Indiana (1), Massachusetts (2), Maryland (6), Minnesota (1), Missouri (2), North Carolina (1), New Jersey (2), New York (12), Pennsylvania (1), Virginia (2) and Wisconsin (1). Sick people’s samples were collected from May 29, 2024, to July 19, 2024. Of 43 people with information available, all 43 have been hospitalized. One person got sick during their pregnancy and remained pregnant after recovering. Three deaths have been reported, including one in Illinois, one in New Jersey, and, as of this update, one in Virginia. Range in ages of illnesses is from 32 to 94 years with median age of 77.
The true number of sick people in this outbreak is likely higher than the number reported, and the outbreak may not be limited to the states with known illnesses. This is because some people recover without medical care and are not tested for Listeria. In addition, recent illnesses may not yet be reported as it usually takes 3 to 4 weeks to determine if a sick person is part of an outbreak.
The Maryland Department of Health and Baltimore City Health Department collected an unopened Boar’s Head liverwurst product from a retail store and identified Listeria monocytogenes. Additionally, the New York State Food Laboratory identified Listeria monocytogenes from a previously collected sample of unopened Boar’s Head liverwurst products collected by the New York State Department of Agriculture and Markets’ Division of Food Safety and Inspection from retail stores. WGS determined both to be the same strain as the strain making people sick in this outbreak. USDA-FSIS conducted traceback of deli meats purchased by sick people in this outbreak to identify producers of interest for further investigation.
CDC advises people to not eat recalled deli meat products. CDC also advises people who are pregnant, aged 65 or older, or have a weakened immune system to avoid eating deli meats or to heat them before consuming.
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.

• 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.
