The aim of this study was to evaluate the occurrence of antibodies to the bluetongue virus (BTV) in animals imported to Poland in 2008, the calves born to bluetongue positive cows and Polish-origin animals kept together with imported cattle. From January 1 to December 15, 2008, a total of 25,495 samples of sera was tested using the c-ELISA and direct ELISA. Out of the tested sera, 1,511 (5.92 %) were found to be positive for BTV. The majority of seropositive cattle were imported to Poland from Germany (987; 65.3%) and the Netherlands (290; 19.2%). Maternal antibodies were detected in 129 (8.5%) samples of sera taken from calves born to seropositive dams of German and Dutch origin. The high number of seroreagents was the result of bluetongue vaccination implemented in BTV-infected EU member States in 2008. In conclusion, it can be stated that surveillance studies should be continued to monitor the actual bluetongue status of Poland. However, an ELISA for the differentiation of infected and vaccinated animals should be introduced to laboratory practice to determine the number of BTV post-infected seropositive animals in the population of imported animals.
