The post-eradication incidence of bovine tuberculosis in seven Central European Countries (Bosnia and Herzegovina, Croatia, Czech Republic, Hungary, Poland, Slovakia and Slovenia) was studied between 1990 and 1999. The majority of cattle to the age of 24 months were screened by tuberculin skin test on annual basis. Tuberculous lesions observed during meat inspection at abattoirs were further laboratory examined by direct microscopy, cultivation and histology for the presence of mycobacteria. Data describing the incidence of the disease in animals for the whole period were obtained from all countries except Bosnia and Herzegovina, where data were obtained after the year 1995. Between the years 1990 and 1999, bovine tuberculosis was diagnosed in a total of 1 084 cattle herds. Nine hundred and seventy five (89.9%) outbreaks of the disease were reported in small herds (10 cows) and 109 (10.1%) outbreaks in large cattle herds (>10 cows). The last outbreak of bovine tuberculosis in cattle was diagnosed in Slovakia, Slovenia, the Czech Republic, Croatia and Bosnia and Herzegovina in 1993, 1993, 1995, 1999 and 1999, respectively. Bovine tuberculosis was diagnosed under proper quarantine in Slovenia in 37 fattening bulls imported from two European countries before animals were introduced to the targeting farms.
