Analysis of problems relevant to serological surveys of pigs for brucellosis was the aim of the studies. In these investigations 74 218 sera from domestic pigs monitored for brucellosis and 3 566 sera from imported pigs were used. For comparison study 159 pig serum samples, collected from three Brucella infected herds, were tested, using following methods: RBT, ELISA, CFT, TAT and 2-ME. The obtained results indicate that serological diagnosis of brucellosis in domestic pigs did not produce major problems. Different situation was observed when some batches of imported pigs were examined. The results of serological investigations were characterised by disquietingly high proportion of samples positive in the RBT, TAT, CFT or ELISA. The analysis of documents and epidemiological inquiry concerning the pigs revealed that they originated from herds struggling with a problem of false positive serological reactions (FPSR), probably due to Yersinia enterocolitica 0:9 infection.
