Australian authorities are investigating the disappearance of hundreds of virus samples from a lab, marking a significant breach of biosecurity protocols. The incident, which took place at Queensland’s Public Health Virology Laboratory in 2021, has prompted calls for a detailed inquiry to prevent similar occurrences in the future.
The missing vials contained samples of dangerous viruses, including Hendra virus, lyssavirus, and hantavirus. The issue arose after a freezer storing the samples broke down. The lab identified the breach in August 2023, but the exact fate of the vials remains unclear. Queensland Health stated it is uncertain whether the samples were improperly removed from secure storage or destroyed due to errors in record keeping.
Despite 323 vials still being unaccounted for, Queensland Health Minister Tim Nicholls reassured the public there is no immediate danger.
“I want to stress that there have been no public health incidents linked to these materials,” Nicholls said during a press conference on Sunday, Dec. 8. “So, we have no evidence so far of any event occurring as a result of the loss or destruction of these materials.”
The investigation will focus on the lab’s internal policies and procedures for handling and storing virus samples, Nicholls added.
The Hendra virus, which can transfer from animals to humans, is primarily carried by flying fox bats. It caused significant concern in 1994 when it led to fatalities in a horse racing stable, including the death of a trainer and 13 horses. Since then, more than 60 outbreaks have been documented.
Hantavirus, also transmitted from animals to humans, has not yet been linked to any human cases in Australia. Meanwhile, lyssavirus is a lethal disease comparable to rabies.
