The occurrence of technological damage in cattle, pigs, sheep and goats reared and slaughtered in the Czech Republic was monitored by evaluation and analyzing results of post mortem inspections of official veterinarians from slaughterhouses in the period from 2010 to 2019. We found that technological damage was the most common in pigs, and less common in cattle, sheep and goats. Compared to other species, pigs have statistically the highest occurrence of lung congestion (51.9%–19.3%, in the order: sows, finishing pigs, piglets), insufficient technology processing (0.200%–0.018%, in the order: sows, finishing pigs, piglets), delayed evisceration (0.04%–0.02%, in the order: finishing pigs, sows, piglets), muscle spoilage (0.033%–0.004%, in the order: piglets, finishing pigs, sows) and over-scalding (0.028%–0.013%, in the order: finishing pigs, piglets, sows). Compared to other species, cattle have statistically the highest incidence of different sensory deviations (7.42%–0.33%, in the order: calves, dairy cows, heifers, bulls) and insufficient bleeding (4.4%–2.9%, in the order: bulls, heifers, dairy cows, calves). In all monitored animal species, a similar level of the occurrence of contamination during the carcass processing was recorded (0.37%–0.00%). In sheep and goats, technological damage is generally lower than in pigs and cattle.

For the monitoring of wild boar interactions with conspecific carcasses, seven wild boar carcasses were placed in different sites in the Czech Republic during winter season. Data were collected by camera traps. In total, 732 visits were recorded of wild boars at the carcass sites. Direct contact with the carcass was detected in 81% of the records. Cannibalism was observed in 9.8% of all recorded visits. The first direct contact was observed on average 30 days after the carcass had been placed in its respective site. Cannibalism was observed on average after 70 days. The effect of sex-age class on direct contact was not proven in our study. The presented findings show that cannibalism in wild boar can play a substantial role in the ASF epidemic. These results highlighted the importance of the removal of infected carcasses from the habitat, which is crucial for African swine fever eradication.
