| Abstract: | Meat-inspection records in an abattoir located in the Fars province (southern part of Iran) from 20 March 1999 to 19 March 2004 were used to determine the prevalence and long-term trend of liver fluke disease in sheep, cattle and goats in the region. A total of 844,039 animals (cattle 131,716; sheep 577,090; goats 135,233) slaughtered in the 5-year period and overall 34,856 (4.1%) livers were condemned. Fasciolosis and dicrocoeliosis were responsible for 54 and 21% of total liver condemnations, respectively. The prevalence of liver condemnations due to fasciolosis was decreased from 3.89, 3.20 and 2.63% in 1999-2000 to 1.07, 0.59 and 0.24% in 2003-2004 for cattle, sheep and goats, respectively. The corresponding features for dicrocoeliosis were similar, declining from 1.47, 1.76 and 2.10% in 1999-2000 to 0.69, 0.34 and 0.25% in 2003-2004, respectively. Drought climatic conditions in conjunction with a greater awareness among farmers could be responsible factors. |
