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.
