Fasciolosis, an important helminth disease of livestock has been confirmed from abattoirs
report in most parts of Nigeria for a long time. Prevalence of fasciolosis among slaughtered
cattle in Ondo State, Nigeria was assessed. Abattoir records of slaughtered cattle were
studied from 2003-2010. A total of 73,761 cattle were slaughtered within the study period.
The study revealed 16.7% peak prevalence of fasciolosis from 13,206 cattle slaughtered in
2008. The 8 year study period recorded 14.5% prevalence. The high prevalence of
fasciolosis translates to high economic loss due to liver damage and low carcass weight.
The disease needs to be considered seriously as a great hindrance to livestock health and
profitability; and also in regard to human health.
