SUMMARY Eglė Kašėtaitė LISTERIA MONOCYTOGENES BACTERIA DETECTION IN FOOD RAW MATERIALS AND PRODUCTS AND RISK FOR HUMANS ASSESSMENT Graduation Dissertation for Master’s Degree The Supervisor of the Work: dr. Silvija Kiverytė Vilnius University Faculty of Medicine Department of Physiology, Biochemistry and Laboratory Medicine Scope of the Work: 57 pages, 4 tables and 24 figures Listeria monocytogenes bacteria are one of the most dangerous pathogens found in the food. Introduced into the raw food materials and products they can cause serious people poisoning and make some substantial economic losses. Currently the world, as well and Lithuania are focused on investigation outbreaks of food-borne pathogen causes on infectious diseases. One of Listeria monocytogenes detection methods in the microbiological food is qualitative detection method. It is widely used in the world, because it is inexpensive, effective and does not affect the environment. Listeriosis - animal and human infectious disease caused by L. monocytogenes Gram-rods. Infected with this disease have an impact of people's age, weakened immune systems, pregnant susceptibility to bacteria, improper food preparation and consumption, or others. The Graduation Dissertation for Master’s Degree is to assess the listeria (Listeria monocytogenes) the prevalence of food materials and products in the year of 2001-2008. The raw food materials and product samples were taken and tested on the National Public Health Laboratory (NPHL) of Klaipeda Department. Objectives: the application of the accredited L. monocytogenes detection method [LST EN ISO 11290-1:2003, LST EN ISO 11290-1:2003/A1:2005] to distinguish and identify L. monocytogenes in the food materials and products, as well to find out the dynamics of the prevalence L. monocytogenes in the food materials and products. The study on the analysis for 2003-2008 incidence of listeriosis Lithuania Material collected from the Infectious Disease Prevention and Control Center (IDPCC). The obtained results are showing that in Lithuania, the same and the world Listeria monocytogenes are found mainly in the fish, meat and their products. In Lithuania the incidence of listeriosis is increasingly being diagnosed under the age of the most illness of the middle-aged persons (from 45 to 64). We also found that listeriosis is characterized by seasonal - mostly recorded in the December and September. |
