How common is Listeria poisoning?
Listeria infection (also known as listeriosis) is uncommon but it can cause death in at-risk people, such as the elderly and people whose immune systems are not working properly. It is also a serious illness in pregnant women and their unborn babies.
“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.”
Is listeriosis a serious disease? Most people with invasive listeriosis require hospital care, and about one in five people with the infection die. When listeriosis occurs during pregnancy, it can cause miscarriage, stillbirth, or newborn death.
For most people, listeriosis is mild and gets better in a few days. You can usually look after yourself at home by resting and drinking plenty of fluids. If you're at a higher risk of getting seriously ill (for example, you're pregnant or have a weakened immune system), you may need antibiotics.
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.
Listeria can be spread to people by several different methods. Eating food contaminated with the bacteria, such as through raw (unpasteurized) milk or contaminated vegetables, is often a source for cases. The bacteria may be passed from mother to fetus during pregnancy or directly to the newborn at the time of birth.
What are the symptoms of listeriosis? Listeriosis can cause mild, flu-like symptoms such as fever, chills, muscle aches, and diarrhea or upset stomach. You also may have a stiff neck, headache, confusion, or loss of balance. Symptoms may appear as late as 2 months after you have eaten something with Listeria.
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.
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).
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.
Is Listeria just food poisoning?
A possible source of the illness: listeria, one of the causes of food poisoning. It's triggered by listeria bacteria that can live in soil, water, dust, animal poop, and other substances. You can get sick if you eat food that carries it.
Results: Nationwide, 1,651 cases of listeriosis occurring during 2009–2011 were reported. The case-fatality rate was 21%.
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.
Listeriosis survivors often are left with serious neurological dysfunctions, including seizures, paralysis and impaired ability to see, hear, swallow or speak.
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.
- Higher-risk people other than pregnant women: Symptoms can include fever, muscle aches, headache, stiff neck, confusion, loss of balance, and convulsions.
- Pregnant women: Pregnant women typically experience only fever, and other non-specific symptoms like chills and headache.
Biospringer delves into the world of Umami, telling the tale of this newest taste's inception and highlighting the benefits it can have in your products. The six states that have been affected by the Listeria outbreak are California, Illinois, Maryland, New Jersey, Massachusetts, and New York.
After a person eats food contaminated with Listeria, symptoms usually begin within a few weeks, but may not occur for up to one month. For pregnant women, it may take up to two months for symptoms to appear. Most people who develop listeriosis seek medical care within two days of developing symptoms.
Wait Until After Your Pregnancy or Take Precautions
If you plan to eat deli meats anyway, we highly suggest cooking them until they are steaming. If the meat is heated to steaming, any present Listeria bacteria should no longer be alive.
"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.
What food is most likely to cause Listeria?
Foods Linked to U.S. Outbreaks of Listeriosis
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.
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.
CDC estimates that Listeria is the third leading cause of death from foodborne illness, or food poisoning, in the United States. An estimated 1,600 people get sick from Listeria each year, and about 260 die.
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.
COOKED MEAT – Listeria is killed by cooking. Thoroughly cooking product to 165ºF/74ºC will kill the bacteria. Consumers at high risk for contracting listeriosis (e.g. pregnant women and the elderly) should reheat deli meats immediately before consumption. FREEZING – Listeria is not killed by freezing.
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.
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.

Avoid eating hot dogs, lunch meats, cold cuts, other deli meats (such as bologna), or fermented or dry sausages unless they are heated to an internal temperature of 165°F or until steaming hot just before serving.
Is Listeria worse than salmonella?
Salmonella was responsible for the three largest outbreaks, and caused the most illnesses and hospitalizations. The outbreaks were from eggs, chicken and raw ground tuna. Listeria caused the most deaths.
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.
Epidemiologic Data
Since the last update on July 13, 2022, two more illnesses have been reported. As of August 2, 2022, a total of 25 people infected with the outbreak strain of Listeria monocytogenes have been reported from 11 states (see map).
Listeria is one of the few bacteria to survive freezing temperatures and grow, albeit slowly, in a refrigerator. The exact range for growth of Listeria is 39.2°F (4 °C) to 98.6°F (37°C). To successfully kill Listeria using temperature controls, it must be cooked at least at 165°F (73°C).
U.S. Listeria Outbreak 2022
The most recent case on the CDC's timeline of the investigation is listed on September 29.
Listeriosis can cause mild, flu-like symptoms such as fever, chills, muscle aches, and diarrhea or upset stomach. You also may have a stiff neck, headache, confusion, or loss of balance. Symptoms may appear as late as 2 months after you have eaten something with Listeria. Many pregnant women do not have any symptoms.
Pregnant women are 10 times more likely than other people to get Listeria infection. Pregnant Hispanic women are 24 times more likely than other people to get Listeria infection. Listeria infection can cause miscarriages, stillbirths, and preterm labor.
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.
Listeriosis can also lead to premature labor, the delivery of a low-birth-weight infant, or infant death. Fetuses who have a late infection may develop a wide range of health problems, including intellectual disability, paralysis, seizures, blindness, or impairments of the brain, heart, or kidney.
22% of cases of perinatal listeriosis result in stillbirth or neonatal death, which makes it crucial to get early treatment. With treatment of the illness, fetal infection and other complications can be avoided. The standard treatment for listeriosis is antibiotics.
Should I worry about Listeria while pregnant?
Listeriosis can be incredibly dangerous for unborn babies and newborns, and can potentially cause serious issues such as infections of the blood or brain, disabilities, and even preterm labor.
Listeriosis only causes a mild illness for most people. However, it can lead to a much more serious illness in unborn babies or newborns when the mother is infected while pregnant. Infection of the fetus may cause miscarriage or stillbirth. Infection of a newborn can lead to pneumonia and death.
If the infection occurs during the second or third trimester of pregnancy, 26% of cases could end up in stillbirths, uterine fetal loss, or abortion. LM tends to occur in late pregnancy.
Although the CDC states that pregnant women are 20 times more likely to become infected than non-pregnant healthy adults, the number of cases of listeriosis in pregnant women is about 17%.
Home treatment for listeriosis is similar to treatment for any foodborne illness. To treat a mild infection at home, you can: Prevent dehydration by drinking water and clear liquids if vomiting or diarrhea occur.
Current methods for identification of L. monocytogenes rely on physiological and biochemical methods. These include Gram stain morphology, catalase, motility, beta hemolysis on blood agar and oblique illumination of colonies on blood free agar (6).
Thorough cooking of food kills Listeria bacteria. Ensure food is cooked thoroughly. 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.
