As of July 19, 2024, a total of 28 people infected with the outbreak strain of Listeria have been reported from 12 states . Sick people’s samples were collected from May 29, 2024, to July 5, 2024. Of 28 people with information available, all have been hospitalized. One person got sick during their pregnancy and remained pregnant after recovering. Two deaths have been reported, 1 in Illinois and 1 in New Jersey.
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.
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.
