Listeria Deli Meat Outbreak: How Older Adults Can Stay Safe as Deaths Grow

2. Older adults are at increased risk for hospitalization

Anyone can get infected with the bacteria, but some people are at greater risk for serious complications, including adults 65 and older.

That’s because as you get older, your “immune system has a harder time recognizing and getting rid of harmful germs, including listeria,” the CDC says. “You also have less stomach acid, which can help kill germs.”

Almost all older adults who get a listeria infection need to be hospitalized, and typically 1 in 6 who are infected die from the illness, the CDC says.  

Other populations at greater risk for serious illness include people who are pregnant, newborns and people with weakened immune systems.

3. Symptoms can be wide-ranging

Symptoms of an infection can vary and typically start within two weeks of eating contaminated food. That said, they can start as early as the same day or as late as 70 days after.

People who are not pregnant may experience:  

• Fever
• Flu-like symptoms, such as muscle aches and fatigue
• Headache
• Stiff neck
• Confusion
• Loss of balance
• Seizures

Listeria can cause intestinal illness with symptoms of diarrhea and vomiting.

The CDC urges people to talk to their health care provider if they ate possibly contaminated food and experience symptoms. “This step is especially important if you are pregnant, are 65 years or older, or have a weakened immune system,” the CDC says.

If you are diagnosed with an infection, work with your local or state health officials to provide details about what you ate in the month before getting sick.

4. You can take steps to protect yourself

The good news is there are things you can do to reduce your risk of getting infected.   

Choose safer foods. People at high risk of severe illness should choose safer food options, the CDC says, avoiding unpasteurized soft cheeses, such as queso fresco and brie, and cold cheese sliced at the deli. Instead, opt for hard cheeses, such as cheddar and parmesan.

If you do eat deli or soft cheeses, make sure you heat it first to 165°F or until steaming hot. You should also heat deli meats, cold cuts and hot dogs before eating them, and avoid coleslaw and potato salad.  

Some other advice: Avoid paté, refrigerated smoked fish and raw sprouts. Eat melon only after it’s just been cut, and do not eat raw (unpasteurized) dairy products.

Clean potentially contaminated surfaces. It’s important to clean your refrigerator, food containers and other surfaces that may have touched affected deli meats or other potentially contaminated foods. The CDC recommends you: 

1. Empty your refrigerator: Remove all items, including shelves and drawers.
2. Clean thoroughly: Wash shelves, drawers and the interior with hot, soapy water. Rinse with clean water, and dry with a towel.
3. Sanitize: For extra protection, you can sanitize with a solution of one tablespoon of bleach per gallon of water after cleaning with soap.
4. Clean containers: Wash any containers that may have stored contaminated meat.
5. Refrigerate promptly: Return food to the refrigerator within two hours to prevent the growth of other pathogens.

Pay attention to recalls. Be sure to throw away any recalled products. [See below for more information on the deli meat products recalled from the current outbreak.]

What to know about the outbreak

The multistate outbreak of listeria has been responsible for 10 deaths and has hospitalized 59 people across 19 states, according to the CDC.

Cases have been confirmed in Arizona, Florida, Georgia, Illinois, Indiana, Louisiana, Maryland, Massachusetts, Minnesota, Missouri, New Jersey, New Mexico, New York, North Carolina, Pennsylvania, South Carolina, Tennessee, Virginia and Wisconsin. The median age of those sickened in the outbreak is 77.

The number of sick people may be higher than what has been reported, because it may take three to four weeks to determine whether a sick person is part of an outbreak and because some people recover without medical care.
