One of the diseases transmitted to humans by ingestion of food products prepared in unfavorable conditions and unhealthy environments is listeria disease. It is a type of bacteria called listeria that causes infections in the form of epidemics and can be fatal, especially in elderly people, newborn babies and people with weak immune systems for various reasons. In our country, there are occasional outbreaks of listeria.

Eight different species of Listeria bacteria have been identified. Among these, the bacteria that cause disease in humans are listeria monocytogenes. These bacteria, which can survive in cold environments, are common in nature. This bacterium mostly lives in water, soil and sewage systems and passes from here to animals, birds and flies. Listeria bacteria, which can be found in fruits and vegetables, red meats, poultry meats, unpasteurized milk and cheeses made with these milk, cause infection in humans. Almost percent of adult people have such bacteria in the feces of 5.

In order to prevent diseases caused by Listeria bacteria, foods of animal origin should be cooked very well, fruits and vegetables should be washed very well, pasteurized milk and foods made from these milk should be consumed. Listeria bacteria can also reproduce in the cold. For this reason, refrigerators and cold rooms should be kept clean and disinfected frequently. In addition, ready-to-eat or perishable foods should be consumed in a short time without waiting.

Sheep were more susceptible to Listeria than cattle. The most common bacterial disease affecting the central nervous system of adult sheep is listeria disease.

In advanced laboratories, listeria bacteria species are analyzed within the scope of microbiological analyzes. During these studies, standards and test methods published by local and foreign organizations are taken as basis.
