People at Risk - People with Weakened Immune Systems

CDC estimates that Listeria infection is the third leading cause of death from food poisoning in the United States. About 1,600 people get sick from Listeria each year, and about 260 die.

People with weakened immune systems due to underlying medical conditions, such as cancer, diabetes, liver or kidney disease, alcoholism, and HIV or AIDS, are more likely to get a Listeria infection. Treatments that make it more difficult for the body to fight off illness, such as steroids and chemotherapy, also can increase the chance of Listeria infection.
