Health officials reported Wednesday that a deadly 1950s flu virus was accidentally sent to thousands of labs throughout the past six months.
According to an article from msn.com, labs incinerated the deadly samples before they could be a threat to the world. More than 1,000 samples were destroyed by U.S. labs.
Meanwhile, U.S. health experts said the threat of public exposure to the virus, known as the H2N2 "Asian flu," appears low. The World Health Organization reported on its Web site that there have been no cases of the flu strain anywhere in the world.
Michael Leavitt, Health and Human Services secretary, is currently reviewing all procedures involving flu viruses and the handling of them.
According to foxnews.com, a Canadian laboratory detected the 1957 pandemic strain on March 26 in a sample that was later traced to a test kit.
