The quality of meat is influenced by several aspects, among which post-vaccination abscesses and bruises stand out as primary factors for the condemnation of carcasses. However, economic losses resulting from improper handling practices can severely compromise the profitability of both the packing plant and the producer. The objective of this study was to estimate the frequency of occurrence of abscesses and bruises in carcasses of animals slaughtered in a packing plant and analyze the economic losses generated by them. The number of animals examined was determined according to the slaughter flow in the packing plant (10-20% of animals/day). Data pertaining to region and number of bruises, abscess location, weight of excised portions and distance from the municipalities of origin of the animals were collected and evaluated by descriptive statistical analysis. The occurrence of lesions was 78% trauma- and 45% abscess-derived. The presence of these lesions resulted in economic losses, representing a depreciation of BRL 2.99/animal in the profit obtained by the cattle farmer. A comparison between the “sex classes” and “bruising” factors revealed that the females had higher occurrence and distribution of bruises and abscesses than uncastrated and castrated males. Bruises were more frequent in the hindquarter region, regardless of the distance, while abscesses were restricted to the forequarter. The weight of discarded tissues was higher on farms less than 200 km away from the packing plant; however, these results were influenced by the number of animals evaluated in the group.
