Study from 2008 to 2010 was planned to estimate the prevalence of L. monocytogenes in various foods of Estonian origin with special reference to ready-to-eat (RTE) foods. Additionally, the detection of the prevalence of Campylobacter spp. in fresh broiler chicken meat products sold in Estonian retail outlets was performed. Regarding to previous tasks, the main aim of the current study was to determine the Campylobacter spp. and Listeria monocytogenes prevalence in Estonian food chain.. Our study in 2008-2010 showed that the prevalence of L. monocytogenes in various RTE food categories, in spite of higher prevalence among raw products, was generally low in Estonia. In 2012 the new project of the Estonian Scientific Council (ETA-g 9315) "Molecular epidemiology of Listeria monocytogenes and Campylobacter spp. in Estonian food chain" started and according to preliminary data from 9-months study period (from January to September 2012) the prevalence of Campylobacter spp in fresh broiler chicken meat was 33.8% from the total of 160 analysed samples. Listeria monocytogenes prevalence in Estonian RTE meat and fish products within 9-months study period in 2012 was 11.7% and only in one fish product with low salt concentration the number of L.monocytogenes exceeded the legal safety limit 1.0 x 102 per gram of product at the last day of product self-life. In average 90% of the Estonian RTE meat and fish products had L.monocytogenes counts less than 1.0 x 101 per gram of product. The final data about the L.monocytogenes prevalence in Estonian RTE food products in 2012 and 2013 will be known at the second half of the year 2013 when the L. monocytogenes 18-months lasting prevalence studies will be summarized.
