Ethics approval and consent to participate
: The pig carcasses were submitted voluntarily by the pig owner, while blood samples were taken from privately-owned pigs within the frame of the monitoring for classical swine fever and Aujeszky disease (carried out by the Ministry of Agriculture, the Veterinary and Food Safety Directorate). Oral consent was obtained from pig owners prior to sampling. The sampling was performed in line with the principles of good veterinary practice and in full respect of animal welfare. Since this study does not include any animal experiments, the Board of Ethics (Croatian Veterinary Institute) decided that no formal approval was required and that the study is in accordance with national legislation [CitationRef removed].
