The authors aimed to describe, as detailed as possible, the epidemiological features of confirmed, alimentary transmitted tick-borne encephalitis (TBE) human cases in Hungary, based on the data of the National Centre for Epidemiology. 27 alimentary transmitted TBE outbreaks were identified with a wide variety of confirmed human cases between 1953-2011. The total number of confirmed alimentary TBE cases was 111, the number of identified cases per outbreaks was 1-26. The slight majority (55.1%) of the cases were males and the most affected age groups were the 10-14 years old boys and men aged 30-39 and 55-59 years. All of the alimentary outbreaks occurred in the north-central and south-western parts of Hungary, three-quarters of the cases (84 patients, 75.7%) were found in Nograd, Heves and Zala county. The source of infection was always raw milk: goat milk caused the majority of cases (101 patients, 91.8%) while cow milk was responsible for 9 cases (8.2%). In 1992-2011, a total of 2280 cases of TBE were reported from which 100 cases (4.4%) were alimentary transmitted. Proportion of milk-borne cases from the total number of infections between 1992-2006 were equally 2.5-4% but it was considerably increased (13.7%) between 2007-2011.
