The director of veterinary services, Dr Letlhogile Modisa said this comes about after reports from farmers of sightings of cattle showing suspicious signs.
Officials from the department of veterinary services followed up the allegations and found five animals that were showing sings that are consistent with the disease.
He explained that export of all meat products from export slaughter and processing plants produced in the last 30 days in Ngamiland is suspended.
He urged farmers to cooperate with the ministry officials and round up animals as and when they are required to do so without fail. Farmers are also expected to report any sick cattle without delay.
He said this disease control measure will be reviewed once the extent of the outbreak is determined.
