Liver condemnation amounted to 14.57% (18,072/ 124,078) in 2000,10.14% (11,998/118,332) in 2001,10.96% (11,372/103,762) in 2002, 9.96% (10,802/ 108,461) in 2003, 5.42% (6,245/114,596) in 2004, and 2.27% (2,750/121,172) in 2005. The overall prevalence of liver condemnation due to F. hepática corresponded to 8.87% (61.239/690.361). In conclusion, fascioliosis was found to be prevalent among sheep in the state of Rio Grande do Sul and to account for major economic losses to farmers, meat packing plants and to the government.
