Out of the 81 food-borne TBE cases registered between 1992 and
2011, 55.1% were male. Also, 4.4% of the total number of TBE cases
were milk-borne. On average, 24.5% of people who drank infected
goat milk suffered from clinical symptoms of neurologic infection.

transmission Historically, only 2 TBE epidemics in Hungary were caused by cow
12
milk. The largest epidemic came from a single goat (of the 75 tested
animals) with 25 cases amongst 154 subjects who had consumed
13
contaminated milk. In that year (2007), almost half of the total
number (30/63) of registered TBE cases were of alimentary origin.
