How soon would you know if you had Listeria?
Symptoms of intestinal illness usually start within 24 hours after eating food contaminated with Listeria and usually last 1–3 days. Symptoms are usually mild. However, some people with intestinal illness develop invasive illness.
“Many people with a healthy immune system are able to fight off a listeria infection and most never even knew they had an infection because the symptoms were mild or non-existent,” said Dr. Price. “However, if you have a weakened immune system, listeriosis can lead to an increased risk of severe infection and death.”
Most listeria infections are so mild they can go unnoticed. However, in some cases, a listeria infection can lead to life-threatening complications, including: Generalized blood infection. Inflammation of the membranes and fluid surrounding the brain (meningitis)
An estimated 1,600 people get listeriosis each year, and about 260 die. The infection is most likely to sicken pregnant women and their newborns, adults aged 65 or older, and people with weakened immune systems. Pregnant women are 10 times more likely than other people to get a Listeria infection.
Intestinal illness: Most people recover from intestinal illness without antibiotic treatment. Antibiotics are needed only for patients who are very ill or at risk of becoming very ill.
This is especially important if you are pregnant, age 65 or older, or have a weakened immune system. If you ate food possibly contaminated with Listeria and do not feel sick, most experts believe you do not need tests or treatment.
Medical treatments. For more severe cases of listeriosis, your doctor will prescribe antibiotics. These are drugs that kill bacteria or slow their growth. Some types of antibiotics that are commonly used for listeriosis include ampicillin and trimethoprim-sulfamethoxazole (Bactrim).
Reheat foods to 'steaming' hot
If you plan to eat previously cooked and refrigerated leftovers, only keep them in the refrigerator for a day and reheat them thoroughly to steaming hot. This will kill Listeria bacteria.

Symptoms
- Diarrhea.
- Nausea.
- Achy muscles.
- Fever.
- Rest: Take it easy until your symptoms subside.
- Hydrate: Even small sips of water or an electrolyte drink, such as coconut water, will help your body replenish fluids.
What are the chances of dying from listeria?
CDC estimates that listeriosis is the third leading cause of death from foodborne illness with about 260 deaths per year. Nearly everyone with listeriosis is hospitalized. The case-fatality rate is about 20%.
A blood test is often the most effective way to determine whether you have a listeria infection. In some cases, samples of urine or spinal fluid will be tested as well.
Compared to other foodborne illnesses, listeriosis is rare but very serious. Even with adequate antibiotic treatment, the disease has a high mortality rate of 20 to 30 percent. Over 90 percent of people with listeriosis are hospitalized, often in intensive care units.
The Listeria Rule states that Lm is a hazard that establishments producing post-lethality exposed RTE meat and poultry products must control through HACCP plans, prevent in the processing environment through a Sanitation SOP, or prevent through another prerequisite program.
Past listeriosis outbreaks in the U.S. have been linked to raw, unpasteurized milks and cheeses, ice cream, raw or processed vegetables, raw or processed fruits, raw or undercooked poultry, sausages, hot dogs, deli meats, and raw or smoked fish and other seafood.
Most healthy patients who are exposed to listeria and develop symptoms will not require any sort of treatment. Their immune system will eradicate the bacteria, and symptoms will tend to go away within three days, though they may last as long as one week.
Listeriosis is treated with antibiotics. The most commonly prescribed treatment is intravenous ampicillin. Many physicians also recommend treatment with the antibiotic gentamicin in combination with ampicillin.
Prewashed greens sometimes cause illness. But the commercial washing process removes most of the contamination that can be removed by washing. All other leafy greens should be thoroughly washed before eating, cutting, or cooking.
Epidemiologic, traceback, and laboratory data showed that cheese made by Old Europe Cheese, Inc. made people sick. As of December 9, 2022, this outbreak is over.
Listeria monocytogenes is an intracellular bacterial pathogen that is frequently associated with food-borne infection. The ability of L. monocytogenes to cross the blood-brain barrier (BBB) is concerning as it can lead to life-threatening meningitis and encephalitis.
Is Listeria destroyed by cooking?
Information. Listeria is destroyed by cooking. Foods are safely cooked when they are heated to a safe minimum internal temperature. Learn more about safe minimum internal temperatures.
Sometimes, raw fruits and vegetables contain harmful germs that can make you and your family sick, such as Salmonella, E. coli, and Listeria. The safest produce to eat is cooked; the next safest is washed. Wash fruits and vegetables under running water—even if you do not plan to eat the peel.
Information. Yes. Listeria can survive on cold surfaces and can also multiply slowly at 24 °F, defeating one traditional food safety defense--refrigeration. Refrigeration at 40 °F stops the multiplication of many foodborne bacteria, but does not kill most bacteria.
But because severe Listeria infections share common symptoms with other diseases, and because detecting the bacteria requires a blood test, medical professionals may not properly diagnose listeriosis for each patient hospitalized with the disease.
Brain and Nerve Damage. Listeria infections can lead to meningitis, an inflammation of the membranes surrounding the brain. If a newborn infant or fetus is infected with Listeria, long-term consequences may include mental retardation, seizures, paralysis, blindness, or deafness.
"How could listeriosis affect my baby?" During the first trimester of pregnancy, listeriosis may cause miscarriage. As the pregnancy progresses to third trimester, the mother is more at risk. Listeriosis can also lead to premature labor, the delivery of a low-birth-weight infant, or infant death.
If a pregnant woman is exposed to listeria and has both a high fever (100.6 degrees F or above) and symptoms, she should be tested for listeriosis and, at the same time, treated with antibiotics.
