Since 1980 Poland has been free of brucellosis. In 1981—1992 from 4.5 (35% — 1981) to 1.5 (17% — 1992) millions of cattle were examined yearly against brucellosis. In 1981 in 401 and in 1992 in 11 animals brucella infections were suspected. Serologically positive animals were culled out and slaughtered. In 1987—1991 1 840 283 (from 34 to 80% animals) in the Gorzów, Legnica, Szczecin, Wrocław and Zielona Góra voivodships were serologically examined against brucellosis. Forty six suspected animals were slaughtered and brucellosis was bacteriologically confirmed in two only cases. Bacteriological examinations of aborted fetuses and placenta from 1309 heifers or cows from these voivodships were brucellosis negative.
