CAPE TOWN (REUTERS) - An outbreak of bird flu has hit an ostrich farm in South Africa, but authorities said it was unlikely to pose a threat to humans, though additional tests were being carried out after another strain killed eight people in China.
The outbreak has prompted restrictions on the movement of the big birds and their products in the Western Cape province, the Western Cape ministry of agriculture said in a statement on Tuesday.
Test samples from an ostrich farm near Oudtshoorn, the centre of South Africa's ostrich export industry, found the presence of the H7N1 virus, the ministry said.
Another strain, H7N9, has killed eight people in eastern China since it was confirmed in humans for the first time last month.
Marna Sinclair, a state vet in the Oudtshoorn area, said there had been previous incidents of H7N1 viruses in the region, but that none were found to be related to the current Chinese strain and no people have fallen ill.
"There is no real concern. We doubt it is a related virus but are conducting tests to make sure," she said.
Two years ago, South Africa culled 10,000 ostriches after an outbreak of another, less virulent form of bird flu halted ostrich-meat exports to the European Union.
