  Youve probably heard of Salmonella and are familiar with the symptoms of salmonellosis. But you may not have heard much about the lesser known foodborne illness listeriosis caused by the bacteria Listeria monocytogenes. […] 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. […] After a person ingests L. monocytogenes, the bacteria grow quickly in the liver and then move into the bloodstream and can invade many places in the body, including the: […] Pregnant women are 18 times more likely to get listeriosis than other healthy adults, and 16 to 27% of all L. monocytogenes infections are in pregnant women.

  Listeriosis, a serious infection caused by eating food contaminated with the bacterium Listeria monocytogenes, is an important public health problem in the United States. Symptoms can show up 1-70 days after exposure to contaminated food and may include vomiting, nausea, cramps, diarrhea, headache, constipation, or fever. […] Some infections become severe and develop into an infection of the brain or lining of the brain and blood poisoning. Some people experience only mild flu-like symptoms. […] Each year in the U.S. about 1,600 persons become seriously ill with listeriosis, and of these, 260 die.

[…] Bacteraemia, sepsis, meningitis, encephalitis, brain abscess, endocarditis, and gastroenteritis are the most common clinical manifestations. […] Key diagnostic factors include presence of risk factors, headache, and altered mental status. […] Other diagnostic factors include fever, diarrhoea and abdominal pain, generalised malaise, flu-like symptoms in pregnancy, poor feeding (neonates), meningismus, cranial nerve deficits, cerebellar signs, focal neurological signs, seizures, hypotension, intra-partum fever, bleeding diathesis with haemorrhage, and cardiac murmur.

• #4 Listeria bacteria cause serious foodborne illness | UCLA Health

  https://www.uclahealth.org/news/article/listeria-bacteria-cause-serious-foodborne-illness

  Listeria is a bacterium that causes a serious foodborne illness known as listeriosis. About 1,600 people get sick from listeria infection each year, and about 260 of them die. […] The most common way to become infected is by eating food that has been contaminated with bacteria. […] It is most dangerous to older adults, people with weakened immune systems, pregnant people, fetuses and newborn babies. […] When confined to the intestines, symptoms of listeriosis can begin from a few hours to a few days after infection. In invasive disease, it can take from several weeks to more than a month for symptoms to appear. For someone with intestinal disease, which tends to be milder, symptoms may include fever, nausea, vomiting, diarrhea, muscle aches and fatigue. In more severe cases, where the disease is systemic, symptoms include headache, stiff neck, loss of balance, confusion and convulsions.

• #5 Listeria (Listeriosis) | FDA

  https://www.fda.gov/food/foodborne-pathogens/listeria-listeriosis

  Listeriosis has a range of symptoms that can vary based on the severity and form of the illness. There are two forms of the disease: the less severe, non-invasive gastrointestinal listeriosis, and the more severe form, invasive listeriosis, which occurs when the Listeria spreads beyond the intestines. […] For the less severe, non-invasive listeriosis, mild symptoms such as fever, muscle aches, nausea, vomiting, and diarrhea may occur, and often persists for 1 to 3 days. […] For the more severe, life-threatening invasive form of the disease, symptoms may include headache, stiff neck, confusion, loss of balance, and convulsions. Invasive listeriosis is a potentially life-threatening event, especially for newborns, adults over the age of 65, and those with weakened immune systems. […] Symptoms of listeriosis during pregnancy may be mild or even go unnoticed, but can lead to severe outcomes, such as miscarriage, stillbirth, premature delivery, or a life-threatening infection of the newborn. […] You should immediately consult with your healthcare provider if you suspect you’ve developed symptoms that resemble a listeriosis infection.

• #11 Why Listeria Stays in Your System for So Long | Marler Clark

  https://marlerclark.com/news_events/why-listeria-stays-in-your-system-for-so-long

  The amount of time from infection to the onset of symptoms typically referred to as the incubation period can vary to a significant degree. Symptoms of Listeria infection can develop at any time from 2 to 70 days after eating contaminated food. […] When a person is infected and develops symptoms of Listeria infection, the resulting illness is called listeriosis. Only a small percentage of persons who ingest Listeria fall ill or develop symptoms. For those who do develop symptoms because of their infection, the resulting illness is either mild or quite severe. […] On the mild end of the spectrum, listeriosis usually consists of the sudden onset of fever, chills, severe headache, vomiting, and other influenza-type symptoms. Along these same lines, the CDC notes that infected individuals may develop fever, muscle aches, and sometimes gastrointestinal symptoms such as nausea or diarrhea. When present, the diarrhea usually lasts 1-4 days (with 42 hours being average), with 12 bowel movements per day at its worst. Few people with normal immune function go on to have more severe, life-threatening forms of listeriosis, characterized by septic shock, meningitis and encephalitis.

  Not everyone infected with Listeria will develop symptoms. Symptoms could include diarrhea, fever, muscle pain, joint pain, headache, stiff neck, backache, chills, sensitivity to bright light, and/or sore throat with fever and swollen glands. These symptoms can begin days to weeks after eating contaminated food. […] Pregnancies affected by or exposed to Listeria can have an increased chance of infection in the uterus, preterm delivery (birth before week 37) or low birth weight (weighing less than 5 pounds, 8 ounces (2500 grams) at birth. Severe infection can increase the chance of stillbirth. […] Newborn babies infected with Listeria can develop either early-onset or late-onset listeriosis. Early onset listeriosis develops 1-2 days after birth, and the baby often has signs of a serious bacterial infection. Late-onset listeriosis occurs 1-2 weeks after birth and usually includes symptoms of meningitis (a condition that causes areas of swelling around the brain and spinal cord in the baby). If not treated quickly, meningitis can lead to long-term problems for some children. Late-onset listeriosis is most likely related to Listeria present in the mother’s birth canal. Not all babies who are exposed to listeriosis during pregnancy will have problems.

  Pregnant women have a mildly impaired immune system that makes them susceptible to Listeria infection. If infected, the illness appears as an acute fever, muscle pain, backache, and headache. Illness usually occurs in the third trimester, which is when immunity is at its lowest. Infection during pregnancy can lead to premature labor, miscarriage, infection of the newborn, or even stillbirth. Twenty-two percent of such infections result in stillbirth or neonatal death. […] For those persons who suffer a Listeria infection that does not resolve on its own, the complications (or sequelae) can be many. The most common is septicemia (bacterial pathogens in the blood, also known as bacteremia), with meningitis being the second most common. Other complications can include inflammation of the brain or brain stem (encephalitis), brain abscess, inflammation of the heart-membrane (endocarditis), and localized infection, either internally or of the skin.

  The amount of time from infection to the onset of symptoms typically referred to as the incubation period can vary to a significant degree. Symptoms of Listeria infection can develop at any time from 2 to 70 days after eating contaminated food. […] When a person is infected and develops symptoms of Listeria infection, the resulting illness is called listeriosis. Only a small percentage of persons who ingest Listeria fall ill or develop symptoms. For those who do develop symptoms because of their infection, the resulting illness is either mild or quite severe. […] On the mild end of the spectrum, listeriosis usually consists of the sudden onset of fever, chills, severe headache, vomiting, and other influenza-type symptoms. Along these same lines, the CDC notes that infected individuals may develop fever, muscle aches, and sometimes gastrointestinal symptoms such as nausea or diarrhea. When present, the diarrhea usually lasts 1-4 days (with 42 hours being average), with 12 bowel movements per day at its worst. Few people with normal immune function go on to have more severe, life-threatening forms of listeriosis, characterized by septic shock, meningitis and encephalitis.

  Listeriosis is the illness caused by Listeria. If people eat foods contaminated with Listeria monocytogenes, they can get sick with listeriosis. Infection can be serious. It is most likely to sicken pregnant women and their newborns, adults aged 65 or older, and people with weakened immune systems. It is rare for people in other groups to get seriously ill with listeriosis. According to the CDC, roughly 1,600 people contract listeriosis each year, and approximately 260 die from the illness. […] The symptoms of listeriosis are diverse and range from mild to serious. Listeriosis is especially dangerous for at-risk groups such as pregnant women and their unborn babies, newborns, older adults, those with weakened immune systems. People receiving some medical treatments, such as chemotherapy for treatment of cancer, are at high risk.
