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.
Listeria 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, used untreated or undertreated heat. Since animals usually carry 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 by unmastated unpasteurized milk and products made from it. The infection is also possible from green vegetables and water. In soil and vegetables, listeria falls by fertilizing 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 for more than 65.6ºC for 30 minutes
Human disease is not transmitted to humans, except in case of infection, when a woman pregnant infects the fruit through the placenta or during delivery. For most healthy people, Listeria monocytogenes does not cause any symptoms, but people with weakened immune systems can develop serious clinical illness. During pregnancy, listeriosis may be a sign of acute upper respiratory or influenza infection, but may be a cause of miscarriage and listeriosis in the newborn. For the elderly and immunosuppressed, L. monocytogenes bacteria can cause meningitis, encephalitis, a serious blood infection, etc.
ULAC specialists recommend:
- Use only thermally processed feed: beef, pork
- Keep raw meat separate from heat-treated or eaten foods to avoid cross-contamination of food
- Wash hands, tools, and green surfaces thoroughly. meat, vegetables
- Avoid unpasteurized and non-aspirated milk and products made from it
- Food prepared in the refrigerator is thawed before use
- Avoid prolonged storage of food for animals stored in the refrigerator, especially paternity
- Avoid cold-smoked seafood, cold-smoked sausages or other p Anas meat products
