ObjectiveTo investigate risk factors responsible for the epidemiology of brucellosis among cattle slaughtered in Nigeria in a bid to implement control strategies.MethodsThis was a cross-sectional and sero-epidemiological survey of bovine brucellosis in two metropolitan abattoirs in Southwestern Nigeria. Between March and August 2013, cattle were screened for antibodies to Brucella spp. by using Rose Bengal test (RBT), and positive samples were subjected to competitive ELISA (cELISA). Parameters of individual animal were also obtained. Data were analyzed by using STATA version 12 and Chi-square; and logistic regression statistics were used to test association.ResultsOverall, 2 480 cattle (1 241 in Oyo; 1 239 in Lagos) were screened. Analysis using RBT revealed a total sero-prevalence of 4.9% (121/2 480), with 7.8% and 1.9% from Oyo and Lagos States respectively. The cELISA result supported 77.7% (94/121) (90.7% in Oyo; 25.0% in Lagos) of the total RBT positive samples. Logistic regression analysis showed that only sex (P ≤ 0.001) and location (P = 0.001) of animal screened had statistically significant effects on seropositivity to Brucella abortus antibodies.ConclusionsOur findings reveal low sero-prevalence of brucellosis among slaughtered cattle in Southwestern Nigeria. Sex and location of abattoirs where animals are slaughtered are major risk factors to be considered in the epidemiology of the disease. Therefore, to promote public health, trade cattle meant for slaughter in Nigeria and African countries where brucellosis is endemic, should be monitored, and positive animals be excluded from the food chain.
