] The World Health Organization urged laboratories Tuesday
] to destroy samples of a flu virus sent out for testing
] purposes after a Canadian lab identified the virus as a
] strain that triggered the 1957 Asian flu pandemic.

] That strain of the virus has not been included in flu
] vaccines since 1968, however, so the WHO warned
] laboratories in the United States, Canada and 16 other
] locations to destroy their samples immediately.

] The College of American Pathologists obtained the
] samples from Meridian Bioscience, a Cincinnati,
] Ohio-based vendor. The strain became known as the
] Asian flu after killing more than 1 million people,
] including about 70,000 in the United States, in a
] 1957 pandemic.

"Oops! Didn't mean to send out that one.. Um, be careful folks!"
