Abstract
This study aimed to provide insights into the main causes of postmortem carcass and organ condemnations in a pig slaughterhouse and evaluate the resulting financial impact of the rejection of edible parts of animals. A population of 307,866 pigs, admitted for slaughter between January 2021 and December 2022 in a Bavarian abattoir, was studied. Regarding the examined carcasses, 2.09% (n = 6422) presented pathological conditions. Of these, 8.12% (n = 522) and 91.88% (n = 5900) were totally and partially confiscated, respectively. The main reason for the complete rejection of carcasses was the occurrence of generalized diseases (62.6%), while the presence of abscesses and traumatic and/or tail lesions was the most frequently implicated (70.7%) in partial condemnations. In the case of the organs, 17.59% (n = 54,145) presented abnormalities, with distributions of 14.71% (n = 45,290), 1.94% (n = 5968), 0.72% (n = 2213), and 0.22% (n = 674) within the examined liver, lung, kidney, and heart specimens, respectively. The principal reasons for liver, lung, kidney, and heart condemnations were the occurrence of parasitic diseases (53.4%), bacterial/viral infections (63.5%), dystrophies/anomalies (98.4%), and bacterial/viral infections (98.5%), respectively. The total financial loss attributable to carcass and organ condemnations was estimated at EUR 392,744.2, which represents 0.40% of the total achievable net revenue without rejections. Of this, EUR 197,120 (0.20%) and EUR 195,624.2 (6.95%) were related to carcass and offal seizures, respectively. The study results offer useful information for veterinarians, stockowners, and epidemiologists to make and set up policies to increase the efficiency and benefits of the swine production system and protect public health.
