Description
Emmanuel Seakamela and co-authors run abattoir surveillance for brucellosis in two South African provinces in a 2026 study, comparing blood tests against DNA detection. The bacterial disease costs livestock production dearly and can infect people. Slaughtered cattle and sheep from Limpopo and the Free State supplied tissue and blood.
Standard paired blood tests flagged only a small share of cattle, under five percent by either pairing. DNA testing told a different story, finding Brucella genetic material in nearly a fifth of cattle and over a quarter of sheep. Almost all DNA-positive cattle had tested negative on blood work, pointing to hidden chronic carriers. Brucella abortus dominated, and the authors urge adding a more sensitive blood test to routine surveillance.
