美国政府工作人员在实验室里发现了六种致命病毒样本,其中一些病毒已存活了超过一个世纪。这些病毒是在最近一次搜寻行动中发现的。今年七月在华盛顿的一家研究所里,工作人员无意中发现了天花病毒样本,在此之后,政府展开了一系列搜寻致命病毒的行动。以下是 Joanna Jolly 的报道:

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.
