ASSESSMENT OF FASCIOLA GIGANTICA INFECTION IN THE LIVER OF CATTLE SLAUGHTERED IN IKPOBA/OKHA AREA COUNCIL, EDO STATE, NIGERIA
This study investigated the prevalence and intensity of Fasciola gigantica infection in the liver of cattle slaughtered in three abattoirs located in Ikpoba/Okha Local Government Area of Edo State, Nigeria. It also estimated the economic implications of the condemned liver. A total of 17,325 cattle were examined in the three abattoirs over a period of 252 days (approximately 69 cattle/day) spanning over the wet and dry seasons; 1,683 cattle were infected with an overall prevalence of 9.71%. In Abattoir A, 11774 cattle were examined with 1069 (9.08%) prevalence. In Abattoirs B and C, 4352 and 1199 cattle, respectively, were examined and 563 (12.94%) and 51 (4.25%) were respectively infected. From the three abattoirs, 155 (0.89%) livers were considered unfit for human consumption due to F. gigantica infection. For the wet season, 1062 (10.89%) cattle livers were infected while 621 (8.20%) were infected during the dry season. The mean intensity of infection during the wet season was 37.80 and 30.42 during the dry season. The financial loss due to infected liver condemnation was at N803,160 (1,947.050USD) showing that liver condemnation arising from F. gigantica infection is a major cause of financial loss to cattle farmers and dealers. There is, therefore, need for adequate veterinary inspections for early detection and treatment of the disease. There should be more meat inspection, especially in private/individual abattoirs.
