Bird flu has been found at four live poultry markets in New Jersey towns near New York, but the discovery was not unusual in the state, a New Jersey official said Thursday. The flu strain involved is not the same as the Asian virus that has killed 19 people and devastated poultry flocks in Asia, the state official said. REUTERS/Tim Shaffer TMS/GN
