The data presented in this thesis resulted from the gross and histopathological interpretation of lesions found in cattle slaughtered for human consumption. The survey for lesions in slaughtered cattle was started in 2011. During the two years of the M.Sci. program the survey was focus in parasitic lesions, which were reported and discussed in the M.Sci. dissertation. The remaining lesions are included in the present thesis and were surveyed in a prospective study (2011-2016) carried out at the Laboratório de Patologia Veterinária at the Universidade Federal de Santa Maria (LPV-UFSM). The purpose of the study describe the gross and microscopical morphology lesions found in cattle in slaughterhouses in order to help veterinary meat inspectors and pathologists alike in identifying lesions found in the carcass and viscera of cattle at meat inspection. During the survey, 540 lesions were observed in cattle at slaughterhouses from different locations in the State of Rio Grande do Sul, Brazil. Seventeen of those were toxic lesions; 65 were neoplastic; 117 were parasitic and 164 were classified as sundry, which included, among others, lesions provoked by improper proceedings during the slaughter (so called technopathies ), lesions with little or no clinical importance. The current study resulted in four scientific papers which are included in the thesis: (1) Atypical cases of actinomycosis in cattle; (2) Granulomatous lesions found in cattle slaughtered for meat production; (3) Mixed apocrine adenocarcinoma of the tail in a cow and (4) Tumors found in cattle from slaughterhouses.
