Listeriosis is an infection caused by Listeria bacteria, named after Joseph Lister, the surgeon and pioneer of antiseptic surgery. It's most commonly caused by eating improperly processed deli meats and unpasteurized milk products.

These signs and symptoms can indicate bacterial meningitis, a life-threatening complication of a listeria infection. The adult humans may have an encephalitic form of listeriosis Listeriosis is a zoonotic disease i.e. Although apparently observed before, the history of listeriosis dates back approximately 60 years. Mayo Clinic is a not-for-profit organization. These include pregnant women, patients undergoing treatment for cancer, AIDS and organ transplants, elderly people and infants. Listeriosis remains an uncommon infection. During pregnancy, blood and placenta cultures are the most reliable ways to discover if symptoms are due to listeriosis. [Article in German] Ender M. PMID: 5879109 [PubMed - indexed for MEDLINE] MeSH Terms Listeriosis is a bacterial infection most commonly caused by Listeria monocytogenes, although L. ivanovii and L. grayi have been reported in certain cases. Listeriosis causes meningoencephalitis and/or septicaemia in adults and newborn infants. Listeriosis is mainly a food-borne infection, and sporadic cases as well as epidemics have been linked to contaminated food [18,43,85,87,130,144]. Listeriosis in humans: an evaluation. Listeriosis is a serious invasive disease that primarily afflicts pregnant women, neonates and immunocompromised adults. Pregnant animals should avoid infected animals. Listeria is a family of bacteria that contains ten species. Accessed Dec. 10. Use safe water and raw materials.). When infection occurs during pregnancy, prompt administration of antibiotics prevents infection of the foetus or newborn. One of these, Listeria monocytogenes, causes the disease listeriosis in humans and animals. Medoff G, Kunz LJ, Weinberg AN. 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. Advertising revenue supports our not-for-profit mission. Human listeriosis is rare and is typically identified in severe, hospitalized cases. The incubation period is short (a few days). Compared to other foodborne pathogens, infections in humans are rare. Centers for Disease Control and Prevention. Listeriosis is one of the most common causes of encephalitis (inflammation of the brain) in adult ruminants. L. monocytogenes in food are killed by pasteurization and cooking. Noninvasive listeriosis (febrile listerial gastroenteritis) is a mild form of the disease affecting mainly otherwise healthy people. Listeriosis is bacteremia, meningitis, cerebritis, dermatitis, an oculoglandular syndrome, intrauterine and neonatal infections, or rarely endocarditis caused by Listeria species. Disease in adult humans is commonly of the encephalitic or septicemic/visceral form. Accessed Dec. 10, 2019. Pregnant women and people who have weak immune systems are at highest risk of contracting a listeria infection. The initial diagnosis of listeriosis is made based on clinical symptoms and detection of the bacteria in a smear from blood, cerebrospinal fluid (CSF), meconium of newborns (or the fetus in abortion cases), as well as from faeces, vomitus, foods or animal feed. Ferri FF. Due to the long incubation period, it is challenging to identify the food which was the actual source of the infection. Newborn infants, pregnant women, the elderly and immunocompromised individuals are particularly susceptible to listeriosis. Outbreaks of listeriosis have been reported in North America, Europe and Japan. People with HIV/AIDS are at least 300 times more likely to get ill than those with a normally functioning immune system. Foodborne listeriosis is one of the most serious and severe foodborne diseases. All rights reserved. 5. Outbreaks of this disease have generally involved the ingestion … Healthy people rarely become ill from listeria infection, but the disease can be fatal to unborn babies, newborns and people with weakened immune systems. The incubation period is short (a few days). Listeriosis can cause severe illness, including severe sepsis, meningitis, or encephalitis, sometimes resulting in lifelong harm and even death. How you catch listeriosis Listeriosis is usually caught from eating food containing listeria bacteria. Excretion in milk is usually intermittent but may persist for many months. Symptoms vary with the organ system affected. Various detection methods, including polymerase chain reaction (PCR), are available for diagnosis of listeriosis in humans. All sectors of the food chain should Implement Good Hygienic Practices (GHP) and Good Manufacturing Practices (GMP) as well as implement a food safety management system based on the principles of Hazard Analysis Critical Control Points (HACCP). Although the number of cases of listeriosis is small, the high rate of death associated with this infection makes it a significant public health concern. Centers for Disease Control and Prevention. Furthermore, the success of such passive surveillance system largely depends on Humans can get listeria organisms while handling aborted fetus, consuming unpasteurised milk, etc. The causative organism, Listeria monocytogenes, is primarily transmitted to humans through contaminated foods. The infection is much more common in infants (10 cases per 100,000 population) and the elderly (1.4 cases per 100,000 population) and has a predominance among males. Pregnant women, the elderly or individuals with a weakened immune system, such as people with immuno-compromised status due to HIV/AIDS, leukaemia, cancer, kidney transplant and steroid therapy, are at greatest risk of severe listeriosis and should avoid high risk foods. The bacteria survive at refrigerator temperature ranges. Frequently asked questions: Pregnancy FAQ 501: Listeria and pregnancy. to humans through food, human listeriosis is often pre-ventable.

Where active surveillance of sepsis and meningitis has been carried out, attack rates of listeriosis are ∼0.7 case per 100,000 population [22]. There are two main types of listeriosis: a non-invasive form and an invasive form. Introduction. Outbreaks of this disease have generally involved the ingestion of foods containing high doses of L. monocytogenes. If you develop a listeria infection, you might have: Symptoms might begin a few days after you've eaten contaminated food, but it can take 30 days or more before the first signs and symptoms of infection begin. Food most often associated with listeriosis include: In past outbreaks, foods involved included ready-to-eat meat products, such as frankfurters, meat spread (paté), smoked salmon and fermented raw meat sausages, as well as dairy products (including soft cheeses, unpasteurized milk and ice cream) and prepared salads (including coleslaw and bean sprouts) as well as fresh vegetables and fruits. First known as a cause of epidemics and sporadic cases in some 50 species of animals, the disease appears now with increased frequency among human populations at risk. The disease occurs worldwide but is diagnosed more often in humans in urban areas in developed countries. Diagnosis is by laboratory isolation. So people who are at higher risk of serious infections should avoid eating the types of food most likely to contain listeria bacteria. 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. The aim of this report was to review data on the investigations of foodborne listeriosis in England and Wales between 1981 and 2015 which includes reviewing data in the peer reviewed literature together with hitherto unpublished data.
