Background: Caseous lymphadenitis (CL) is considered one of the most important diseases, economically, in sheep and goats in the United States, Canada and Australia. Annual losses in wool production reaches 17 million dollars in Australia, the disease cause important impact in Europe, Africa, Middle East, Australia, and in the Americas. The CL is a chronic disease, which affects mainly sheep and goats. The etiologic agent is the Corynebacterium pseudotuberculosis. The presence of the agent in feces contributes to environmental contamination and increases the risk of infections in herds. For countries with international marketing of live animals, the CL is a serious health problem to livestock disease-free. The objective of this study was to report the occurrence of lesions caused by CL in sheep slaughtered under the official service of inspection of the state of Rio Grande do Sul and correlate it to the economic losses due to the lesions found. Materials, Methods & Results: Data concerning the fate of raw materials, the total number of animals slaughtered and injuries from the ante and post-mortem were provided by the Federal Inspection Service (SIFs do Ministério da Agricultura, Pecuária e Abastecimento no Rio Grande do Sul (SFA/MAPA-RS). Data from the slaughtered animals were generated by the information system management service inspection (SIGSIF), requested in official character, which included the daily slaughter maps, as well as monthly and annual reports. Were collected data from 932,547 sheep slaughtered under federal inspection, from January 2004 to August 2009. The number of cases recorded only in Federal Inspection Service was 348 and the number of animals condemned at slaughter was 86. Through assigning an average weight of 17,57 kg per carcass value of 8.50 kg-1 of carcass based in the literature, the estimated direct economic losses caused by lesions of CL in the period relating to the condemnation of carcasses in slaughter plants under federal inspection was R$ 12.975,27(US$ 7.289,47) (US$ 1,00 = R$ 1.78). Nine hundred and thirty two thousand and five hundred forty-seven sheep were slaughtered under federal inspection in Rio Grande do Sul in the period from 2004 to 2009, CL occurred on 0,037% of the carcasses (n = 348) and determined the total condemnation of 0,009% (n = 86). Discussion: The injuries due to CL are significant the cause condemnations of carcasses, the condemnation rate for CL is 3 to 5% for carcasses of adult sheep on most of the developed countries, on the other hand, in Argentina it had been reported 11% of condemnation, in Brazil little effort has been done on this way, and the data that are published shows that the Northern part of the country has been reporting more cases of condemnation due to CL. What is noted in this study is that CL has not been reported in big amounts in the state, what could lead and give the change of eradication of it from this part of Brazil. The disease still occurs in sheep in Rio Grande do Sul, it has been found at slaughter by lesions occurred during the whole period from 2004 to 2009, in greater or lesser degree, condemnations and economic losses will continue to be reported while sanitary measures are not well adopted in Brazil.
