Objective. The research was conducted to evaluate the main causes of carcass condemnation, as well as the financial loss caused by it, at a commercial slaughterhouse located in Dourados, MS, Brazil. Materials and methods. The data related to carcass condemnation, for the years 2007 to 2009 was obtained from a commercial slaughterhouse, located in the city of Dourados, MS, Brazil, and turned into a percentage of the total number of animals slaughtered during that period. The most frequent causes of carcass condemnation (total or partial) were grouped into classes (pleurisy + pneumonia; enteritis; arthritis; abscesses; fractures/hematomas + contusions + death). The financial loss by the slaughterhouse was estimated using the condemnation data. Results. The total rate of carcass condemnation was low and tended to stability (<0.45%). The most prevalent causes of condemnation during the study period were abscesses and death in the transport, which together accounted for approximately 40% of all condemnation. The condemnation due to health problems tended to decrease or to be stable over the years. However, the condemnations caused by management problems (abscesses, fractures, contusions and death) showed a significant increase. The average loss to the integrative company according to the carcasses condemnation was exceeding U$1,600,000.00 in the years studied. Conclusions. The main causes of carcass condemnation come from management failure. The annual loss by the company can be invested in the training of manpower in order to reduce the rates of carcass condemnation.
