美國政府工作人員在實驗室裏發現了六種致命病毒樣本,其中一些病毒已存活了超過一個世紀。這些病毒是在最近一次搜尋行動中發現的。今年七月在華盛頓的一家研究所裏,工作人員無意中發現了天花病毒樣本,在此之後,政府展開了一系列搜尋致命病毒的行動。以下是 Joanna Jolly 的報道:

Workers searching the government premises found six different types of microbes classed as being so dangerous they're required to be stored at high-secure facilities.

Instead, they were found in regular laboratories. They included bacteria that cause the plague and nerve toxins that cause botulism. A vial of the highly poisonous toxin ricin was also found, dating from nearly a century ago.

Authorities said although the microbes had not been stored correctly, they had been properly sealed, so posed no danger to staff. They have all been destroyed.
