" Three poultry farm workers have been tested positive for the H5N2 avian influenza strain but none have displayed flu symptoms, Taiwan's disease control authorities said.
They were among 141 people working at five poultry farms where the avian flu was discovered.
Tens of thousands of chickens in the farms have been culled since the outbreak of H5N2 in the past few months.
Medical experts believe the test results may well be a cross-reactivity since all the three persons had flu jabs last year, Xinhua news agency reported.
Cases of humans who tested positive for H5N2 while showing no health disorders were previously reported in South Africa and Japan between 1993 to 1995.
Taiwan authorities confirmed the outbreak of H5N2 following sporadic reports in farms in central Taiwan.
The flu has so far affected chicken farms in Changhua, Tainan and Nantou."
