South Africa : Bird Flu Found at Three More Ostrich Farms

Via The Poultry Site :

" SOUTH AFRICA : Evidence of the bird flu virus has been found at three further ostrich farms in the Western Cape.

The veterinary authority sent Follow Up Report No. 7 dated 22 September to the World Organisation for Animal Health (OIE).

Surveillance has revealed evidence of the bird flu virus – H5 and H6 sub-types – at three further ostrich farms in Western Cape, the same province where previous outbreaks occurred.

According to the report, all three premises were commercial ostrich farms. Farms tested positive on serology during routine surveillance but tested negative on PCR and no virus could be found. Diagnosis only confirmed after several follow-up PCR tests. South Africa only reports outbreaks on confirmation on PCR tests. Initially no clinical signs or mortalities were seen.

Stamping out in positive farms is taking place."
