Key points
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.

Where sick people live
This map shows where the 43 people in this Listeria outbreak lived.
This outbreak may not be limited to the states with known illnesses, and the true number of sick people is likely higher than the number reported. This is because some people recover without medical care and are not tested for Listeria.
