title: Survey of cattle fascioliasis in Tsuyama Abattoir.
abstract: OBJECTIVE
  The aim of this study was to survey the prevalence of fascioliasis in slaughtered cattle in order to provide breeders with feedback which may prevent cattle fascioliasis, as well as human fascioliasis.
  
  
  METHODS
  The results of meat inspection and the information extracted from the Discriminative Data Base on Individual Livestock in Japan were analyzed statistically in 6,224 cattle slaughtered at the Tsuyama Abattoir during the fiscal year 2002.
  
  
  RESULTS
  The age-adjusted fascioliasis and cholangitis rates of all cattle were 2.0% and 7.2%, respectively. When analyzed by cattle breed, both rates were significantly higher in Japanese native cattle than in Holstein or Jersey (Chi-square test, p<0.01). The cattle raised in Okayama Prefecture, Tochigi Prefecture and Shimane Prefecture were significantly different from cattle raised in other prefectures in the age-adjusted fascioliasis and cholangitis rates.
  
  
  CONCLUSIONS
  The age-adjusted fascioliasis and cholangitis rates of all cattle can be considered as nationwide rates for slaughtered cattle. The results of the comparisons suggest that cattle fascioliasis is related to feeding with rice straw and that the measures to prevent cattle fascioliasis might differ a mong prefectural governments.
