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. The challenges for controlling L. monocytogenes are considerable given its ubiquitous nature, high resistance to common preservative methods, such as the use of salt, smoke or acidic condition in the food, and its ability to survive and grow at refrigeration temperatures (around 5 °C). it transmits from animals to humans.

Gastroenteric manifestations with fever also occur. 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. Various detection methods, including polymerase chain reaction (PCR), are available for diagnosis of listeriosis in humans. Listeriosis is not directly transmissible from animals to humans. Unlike many other common foodborne diseases causing bacteria, L. monocytogenescan survive and multiply at low temperatures usually found in refrigerators . Listeriosis. Centers for Disease Control and Prevention. The disease occurs worldwide but is diagnosed more often in humans in urban areas in developed countries. Listeriosis can cause severe illness, including severe sepsis, meningitis, or encephalitis, sometimes resulting in lifelong harm and even death. Newborn infants, pregnant women, the elderly and immunocompromised individuals are particularly susceptible to listeriosis. Gelfand MS.

Compared to other foodborne pathogens, infections in humans are rare. In pregnant women, it causes fever and abortion. Those at risk of severe illness are the elderly, fetuses, newborns and those who are immunocompromised. Listeriosis in humans is seen primarily in pregnant women, newborns, elderly, and immunosuppressed (e.g. The control of L. monocytogenes is required at all stages in the food chain and an integrated approach is needed to prevent the multiplication of this bacteria in the final food product. J Infect Dis. Diagnosis is by laboratory isolation. [Listeriosis in humans]. The incubation period is short (a few days). A blood test is often the most effective way to determine whether you have a listeria infection. La listériose humaine est une maladie rare et qui se caractérise typiquement par des cas sévères hospitalisés. Listeriosis. 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. Pregnant animals should avoid infected animals. Infection can also be transmitted between humans, notably from pregnant women to unborn babies. 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]. Ferri FF.

Disease in adult humans is commonly of the encephalitic or septicemic/visceral form. This form of disease is characterized by severe symptoms and a high mortality rate (20%–30%). In: Ferri's Clinical Advisor 2020. Listeria bac… Human listeriosis is rare and is typically identified in severe, hospitalized cases. This network is managed jointly by WHO and FAO. Listeriosis can be treated if diagnosed early. This guidance includes microbiological criteria (i.e. Any use of this site constitutes your agreement to the Terms and Conditions and Privacy Policy linked below. foods with a long shelf-life under refrigeration (, foods that are consumed without further treatment, such as cooking, which would otherwise kill. Discard foods that are past their "best before" date, and properly wash … Be extremely careful when handling sick or dead animals. 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. If you have a high fever, severe headache, stiff neck, confusion or sensitivity to light, seek emergency care. Severe infections can cause headaches, meningitis, convulsions, and death. If the listeria infection spreads to your nervous system, signs and symptoms can include: During pregnancy, a listeria infection is likely to cause only mild signs and symptoms in the mother. The invasive forms of listeriosis in humans include septicaemia, meningitis (or meningoencephalitis), and encephalitis (rhombencephalitis). There are 10 distinct species of … 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. 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. In these groups, listeriosis can present as infection of the bloodstream or brain. It's most commonly caused by eating improperly processed deli meats and unpasteurized milk products.

Symptoms include diarrhoea, fever, headache and myalgia (muscle pain). Humans can get listeria organisms while handling aborted fetus, consuming unpasteurised milk, etc. L. monocytogenes in food are killed by pasteurization and cooking. 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. People can get infected by eating the following: Unborn babies can contract a listeria infection from the mother. Pregnant women and people who have weak immune systems are at highest risk of contracting a listeria infection. Neonatal listeriosis. Food manufacturers should also test against microbiological criteria, as appropriate, when validating and verifying the correct functioning of their HACCP based procedures and other hygiene control measures. 5.

However, listeriosis can cause severe disease in vulnerable groups, including the elderly, pregnant women, unborn and newborn babies, and people with impaired immunity. On the basis of the surveillance program, further research should be conducted to uncover the reason for the prevalence and pathogenic mechanism of the highly epidemiological hypervirulent ST87 strains in China. One of these, Listeria monocytogenes, causes the disease listeriosis in humans and animals. The symptoms include fever, myalgia (muscle pain), septicemia, meningitis.
