Samples were taken at 6 processing dairies of 187 farm milks, which were submitted to the Milk Ring Test. 40 (21.4%) gave positive reactions. In the case of one herd, where the farmer requested a follow-up investigation, 9 cows out of 34 gave positive reactions and five of these were subsequently confirmed to be infected with Brucella Abortus.
