When Food Bites Back: Protecting Those at Risk for Listeria Food Poisoning
A new Vital Signs report on foodborne illness looks at one of the most deadly germs spread by contaminated food—Listeria—and the people it strikes the hardest.
In the United States, an estimated 1,600 people get sick from Listeria germs each year. Of these, 260 die 1.
At least 90% of people who get Listeria infections are in highly vulnerable groups. Healthy children and adults occasionally get infected with Listeria, but they rarely become seriously ill.
Key Facts for Those at Greatest Risk:
The following groups are at increased risk:
- Pregnant women: About one in seven (14%) cases of Listeria infection occurs during pregnancy 2. Infection during pregnancy can cause fetal loss (miscarriage or stillbirth), preterm labor, and illness or death in newborn infants.
- Older adults: More than half (58%) of Listeria infections occur among adults 65 and older 2.
- Adults 65 years and older are about 4 times more likely than the general population to get Listeria infection 2.
- People with weakened immune systems: Individuals within this group are also considered high risk for Listeria infection due to underlying medical conditions such as cancer and immunosuppresive therapy (i.e., steroids, chemotherapy, radiation), liver or kidney disease, diabetes, alcoholism, and HIV/AIDS.
