It is reported that a laboratory in Australia lost hundreds of deadly virus samples, causing a "major loophole" in biosafety. On December 8th, Queensland Health Minister announced that there are currently 323 bottles of live virus missing. These include nearly 100 bottles of Hendra virus, two bottles of Hantavirus and 223 bottles of rabies virus-all of which are extremely deadly to human beings. The Queensland authorities insist that although these samples can be used as weapons, it is "not something that amateurs can do". The sample was lost in 2021, but investigators did not confirm the leak until August 2023. Queensland authorities waited for a year before being allowed to open the freezer where the samples were stored, and only this month were they able to confirm that the samples were lost. It is not clear where these samples may be or whether they have been destroyed. However, there is no evidence that the public is at risk of infection because of the disappearance of samples.
