Prevalence and Pathology of Fasciola Species in Slaughtered Cattle

Studies on the prevalence and pathology of Fasciola specie were carried out in nine abattoirs in Ilorin, capital city of Kwara State, Nigeria. The research was conducted during the period August, 2006 - May, 2007. Of the 63,649 cattles examined at the various abattoirs which are lpata, Sango, Oloje, Baboko, Oke-oyi, Iporin, Panada, Oke-ose and Marafa, 1,434 representing 25.2% were infected with Fasciola species while 114 representing 6.5% were condemned. Iporin slaughter slab had the highest prevalence of 3.6%, followed by panada with 3.4% and Ipata having the least prevalence of 1.6%. Similarly analysis of data on monthly basis showed that March had the highest prevalence of 2.8%, followed by April with 2.6% and December with the least prevalence of 1.8%. Overall infestation was 22.7% while overall condemnation was 6.5%. There was a significant difference （X^2 = 23.7, P 〈 0.05） in the monthly infestation rate. Also, there was no significant difference （X^2 = 10.7, P 〉 0.05） between the infection rate and condemnation among the various abattoirs. The factors responsible for the prevalence of Fasciola specie and pathology of infection are highlighted.
