It’s a bacteria found in soil, water and vegetation and is transmitted to humans through ingestion of food contaminated with the Listeria monocytogenes bacterium. Signs and symptoms of a listeria infection in a newborn can be subtle, but can include: If you've eaten a food that's been recalled because of a listeria outbreak, watch for signs or symptoms of illness. (1964). 1963 Nov;30(4):461-5. Listeria is zoonotic and can be transferred to humans. The bacteria survive at refrigerator temperature ranges. Gelfand MS. Clinical manifestations and diagnosis of Listeria monocytogenes infection. Humans can get listeria organisms while handling aborted fetus, consuming unpasteurised milk, etc. PMID: 5000073 [PubMed - indexed for MEDLINE] This form of disease is characterized by severe symptoms and a high mortality rate (20%–30%). These signs and symptoms can indicate bacterial meningitis, a life-threatening complication of a listeria infection. The incubation period is usually one to two weeks but can vary between a few days and up to 90 days. It thrives in aerobic conditions and … Listeriosis What is listeriosis and what causes it? Invasive listeriosis is a more severe form of the disease and affects certain high risk groups of the population.

Newborn infants, pregnant women, the elderly and immunocompromised individuals are particularly susceptible to listeriosis. Furthermore, the success of such passive surveillance system largely depends on Listeriosis is a series of diseases caused by the bacteria L. monocytogenes, outbreaks of which occur in all countries. In addition, producers manufacturing food associated with risks of Listeria must conduct environmental monitoring to identify and eliminate niche environments, including areas that favor the establishment and proliferation of L. monocytogenes. Accessed Dec. 7, 2019. in humans in Slovenia, which was 0.63–0.87 per 100,000 people in the 2013–2017 period [9]. The national human listeriosis pilot surveillance started in 2013, and a total of 133 listeriosis cases have been collected until now. 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and Wales between 1981 and 2015 which includes reviewing data in the peer reviewed literature together with hitherto unpublished data. Listeria bacteria can survive refrigeration and even freezing. Listeriosis is a serious infection usually caused by eating food contaminated with the bacterium Listeria monocytogenes. Various detection methods, including polymerase chain reaction (PCR), are available for diagnosis of listeriosis in humans. The prevalence of ruminant listeriosis in Slovenia is most likely underesti-mated because many diseased animals do not undergo post mortem examination. Infection can also be transmitted between humans, notably from pregnant women to unborn babies. Mayo Clinic; 2018. https://www.cdc.gov/listeria/index.html. Disease in adult humans is commonly of the encephalitic or septicemic/visceral form. However, listeriosis can cause severe disease in vulnerable groups, including the elderly, pregnant women, unborn and newborn babies, and people with impaired immunity. These include pregnant women, patients undergoing treatment for cancer, AIDS and organ transplants, elderly people and infants. This content does not have an Arabic version. Listeria bac… Be extremely careful when handling sick or dead animals. This content does not have an English version. Mayo Clinic is a not-for-profit organization. In: Ferri's Clinical Advisor 2020. Noninvasive listeriosis (febrile listerial gastroenteritis) is a mild form of the disease affecting mainly otherwise healthy people. Symptoms include diarrhoea, fever, headache and myalgia (muscle pain). Infants acquire the infection in 2 ways. WHO’s main tool to assist Member States in surveillance, coordination and response to outbreaks is the International Network of Food Safety Authorities (INFOSAN) which links national authorities in Member States in charge of managing food safety events. What is listeriosis? WHO and FAO have published an international quantitative risk assessment of Listeria in ready-to-eat foods This has formed the scientific basis for the Codex Alimentarius Commission Guidelines on the Application of General Principles of Food Hygiene to the Control of Listeria Monocytogenes in Foods. It is important to respect the shelf-life and storage temperature written on labels of ready-to-eat foods to ensure that bacteria potentially present in these foods does not multiply to dangerously high numbers. They can be found in soil, water, vegetation and the faeces of some animals and can contaminate foods. There are two main types of listeriosis: a non-invasive form and an invasive form. Eating contaminated food with high numbers of L. monocytogenes is the main route of infection. The causative agentListeria monocytogenes is primarily a psychrophilic soil-borne bacterium with a wide pathogenic … Modern technologies using genetic fingerprint - Whole Genome Sequencing (WGS) - allow for more rapid identification of the food source of listeriosis outbreaks by linking L. monocytogens isolated from patients with those isolated from foods. 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. Antibiotics are used to treat severe symptoms such as meningitis. A single copy of these materials may be reprinted for noncommercial personal use only.
