According to data from the Center for Infectious Diseases and AIDS (ULAC), individual cases of listeriosis are recorded each year in Lithuania. In the first 2018 9 cases of this disease (2 deaths) were detected in Lithuania in the first half of the year.
2013-2017. Listeriosis was diagnosed in 37 people, 9 of whom died (24%). Most cases of this disease were detected in 2016. (10 avv.) And 2017 (9 otv.).
According to the European Center for Disease Prevention and Control, the incidence of listeriosis has increased in recent years. From 2014 More than 2000 cases of listeriosis were recorded in the European Union (EU) / European Economic Area (EEA) countries. This disease is most often diagnosed in people over 65 years old.
Listeriosis is caused by the bacterium Listeria monocytogenes. This is rare, with a high mortality rate of 20-30%. The main source of infection is animal feed, untreated or insufficiently treated with heat.
Since animals are mainly carriers of bacteria, the meat of these animals, milk and their products can be a source of infection. Listeria can also be contaminated with food.
Very often, Listeria can be contaminated with unmastined unpasteurized milk and products made from it. It is also possible to be infected with green vegetables and water.
In soil and vegetables, listeria enter through the fertilization of cattle dung. L. monocytogenes can reproduce at low temperatures (in the refrigerator) and is resistant to high salt levels. The bacterium L. monocytogenes is destroyed by pasteurization or by heating at more than 65.6 ° C for 30 minutes
It is believed that the disease is not transmitted to humans, except in case of infection when it is infected. a pregnant woman infects the fruit through the placenta or during delivery. Listeria monocytogenes does not cause symptoms, but people with weakened immune systems can develop serious clinical illness.
Listeriosis may be a sign of acute upper respiratory infection, but it may be a cause of miscarriage and listeriosis. In the elderly and immunosuppressed, L. monocytogenes can cause meningitis, encephalitis, severe blood infection, etc.
ULAC specialists recommend: Only use thermally processed animal feeds: beef, pork, poultry, etc. Wash the green vegetables well before use. Store raw meat separately from heat-treated or eaten foods to prevent cross-contamination of food. Wash hands, tools and surfaces thoroughly after contact with green meat or vegetables. Avoid unpasteurized raw milk and products made from it. Plus the prepared foods in the refrigerator must be well heated before being eaten. Avoid any food stored in the refrigerator for a long time, especially painted. Avoid cold-smoked seafood, cold-smoked sausages or other similar meat products
