An estimated 1,600 people get sick from Listeria each year, and about 260 die.
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. Over 90 percent of people with listeriosis are hospitalized, often in intensive care units.
While cases of listeriosis are relatively rare — roughly 1,600 people are diagnosed with it each year, Dr. Hunter says — listeriosis can be lethal. About 260 of those 1,600 people die as a result of the infection.
Listeriosis is a serious infection usually caused by eating food contaminated with the bacterium Listeria monocytogenes. An estimated 1,600 people get listeriosis each year, and about 260 die.
It is important to note that while listeriosis can be a very severe illness, the number of cases reported in Australia each year is relatively rare, with around 60 total cases reported to health departments each year.
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%. Nearly one-quarter of pregnancy-associated cases result in fetal loss or death of the newborn.
The good news is that listeriosis in pregnant women is very rare in Australia and New Zealand. If you avoid soils and foods at risk of being contaminated it's very unlikely that you will be infected. It is also important to follow safe hygiene habits when preparing and cooking foods.
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.
Listeria infection is a foodborne bacterial illness that can be very serious for pregnant women, people older than 65 and people with weakened immune systems. It's most commonly caused by eating improperly processed deli meats and unpasteurized milk products.
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.
Treatment of listeria infection varies, depending on the severity of the signs and symptoms. Most people with mild symptoms require no treatment. More-serious infections can be treated with antibiotics.
Foodborne listeriosis is one of the most serious and severe foodborne diseases. It is caused by the bacteria Listeria monocytogenes. It is a relatively rare disease with 0.1 to 10 cases per 1 million people per year depending on the countries and regions of the world.
“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.”
The bacteria are most likely to sicken people who are pregnant and their newborns, adults aged 65 or older, and people with weakened immune systems. Other people can be infected with Listeria, but they rarely become seriously ill.
Can listeriosis be cured? Yes, there is a cure for listeriosis. Your healthcare provider can prescribe antibiotics to rid your body of the infection. Your healthcare provider is more likely to prescribe antibiotics to babies or if you're pregnant, 65 or older or have a weakened immune system.
The chance of becoming infected with Listeria from lunch meat is pretty rare. Food manufacturers take steps to prevent it before packaging. If you're pregnant and have previously eaten deli meat, don't worry. But it's probably best to satisfy any future cravings for an Italian sub until after delivery.
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.
Listeriosis Symptoms Don't Always Show Up Right Away: If you unknowingly eat something contaminated with listeria, symptoms of an infection can show up as early as one week, and as late as two months afterwards. Listeriosis symptoms are similar to the flu, and include fever, chills, muscle aches and an upset stomach.
Pregnant women in their third trimester are most vulnerable to contracting the illness, but it's possible to get infected at any point during pregnancy. If you begin experiencing these symptoms, contact your doctor and inform them of any food you recently ate. A blood test can confirm a diagnosis of listeriosis.
While listeriosis can affect anyone, it's particularly worrying for pregnant women because it can cause miscarriage, stillbirth or premature birth. Newborn babies infected with listeria from their mother can become seriously ill with meningitis, blood poisoning or other infections.
Infection can occur at any time during pregnancy, but it is most common during the third trimester when your immune system is somewhat suppressed. Be sure to contact your health care provider if you experience any of these symptoms. A blood test can confirm an infection from listeriosis.
Most of the time, pregnant women who are infected with listeriosis don't feel sick. However, they can pass the infection to their unborn babies without even knowing it. That's why prevention of listeriosis is very important.
An exposed pregnant woman with a fever higher than 38.1°C (100.6°F) and signs and symptoms consistent with listeriosis for whom no other cause of illness is known should be simultaneously tested and treated for presumptive listeriosis. Diagnosis is made primarily by blood culture.
Penicillin, ampicillin, and amoxicillin have been used most extensively in the treatment of listeriosis. Most experts recommend 6 g or more per day of ampicillin for treatment during pregnancy. This dosage provides adequate intracellular penetration and crosses the placenta in adequate amounts.
