Abstract
The aim of the study was to analyse the results of the post-mortem sanitary and veterinary examinations of wild boar by the Veterinary Inspection in Poland between 2015 and 2019. The examination took into account changes such as emaciation, septicaemia and pyaemia, parasitic diseases and other. Analyses determined the number of animals examined, the number of carcasses with lesions, and the number of carcasses declared unfit for consumption. During the study period, more than 680,000 wild boars were subjected to sanitary and veterinary tests in Poland. Symptoms or lesions were found in 11,566 animals (1.70%), and 10,883 (1.60%) animals were declared unfit for consumption. The percentage of wild boar carcasses with lesions examined by year ranged from 1.23% in 2015 to 2.02% in 2019 and the percentage of wild boar carcasses declared unfit in relation to all carcasses tested ranged from 1.23% in 2015 to 1.88% in 2019. Parasitic lesions were found in 3488 wild boar carcasses, accounting for 30.16% of all changes recorded in wild boar carcasses. The most common parasitic disease was trichinellosis and the most frequent change was emaciation, which was recorded in 2665 (0.39%) animals. Putrefaction is a common lesion in wild boar carcasses, and was detected in 2546 (0.37%) animals. Territorial differences were found in the frequency of lesions in wild boars in Poland. The most trichinellosis cases in carcasses was recorded in Zachodniopomorskie Voivodeship (748) and Wielkopolskie Voivodeship (638). Kujawsko-pomorskie Voivodeship and Wielkopolskie Voivodeship together had a total of 2324 cases of emaciation, accounting for 87.2% of all cases of these changes registered in the study period. The largest number of wild boar carcasses declared unfit for consumption was found in Kujawsko-pomorskie Voivodeship (3356) and Zachodniopomorskie Voivodeship (2692), together accounting for 6048 unfit carcasses, or more than 55% of all carcasses declared unfit for consumption during the study period. The number of wild boars diagnosed with trichinellosis increased during the study period and was highest during 2019, with a systematic increase in the percentage of carcasses declared unfit for consumption in relation to the total.
