Epidemiological comments Suspected cases of FMD were detected at Ardlui farm, about 7km south of Chegutu town, by the area veterinary extension workers (VEW) on the 17th of January 2018. The VEW immediately alerted the district veterinary officer and provincial Veterinary Officer who both immediately drove to the farm and tentatively confirmed the disease on clinical signs. A total of 13 cattle in a herd of 239 beef cattle on the farm were seen with FMD lesions. Farm records indicated there were four movements into the farm and three movements out of the farm between 1 December 2017 and 17 January 2018. Animals that moved into the farm were 2 bulls on 2 December 2017 from Pilosoff farm in Bulawayo, eight cows on 9 December from Mt Hampden sale, 17 heifers on 12 December from Mt Hampden sale and eighteen cows on 23 December from Aldington farm in Beatrice Seke district. Three of the outward movements were all to Mt Hampden Sale on the 9 December 2017, 3 January 2018 and 15 January 2018. Movement permit records were used to map out all destinations of cattle that were on the three sales that had animals from Ardlui farm. A list of all the source farms that sent animals to Ardlui farm and all destination farms that received animals from the three sales in which Ardlui farm participated has been compiled to facilitate trace back and trace forward investigations by respective provinces. Disease surveillance inspections on these target farms are still ongoing. The source of infection has not yet been identified as no evidence of disease has been detected at any of the source farms that sent animals to Ardlui farm in the recent past. Trace forward investigations have shown the Mt Hampden sales on the 3rd and 16th January 2018 sold infected cattle as outbreaks have been detected at some of the properties that received animals from these sales. To date infection has been detected at two destination sites in Marondera (Maganga Estate) and Macheke (Nyadema farm) all in Mashonaland east province. Vaccinations are underway on the three infected areas while investigations continue.
