Dozens of viruses have been detected mixing in animals at fur farms in China, some of which are new and have the potential to spill over into humans, researchers said on Wednesday (Sep 4).
Since the COVID-19 pandemic, scientists have been warning that farming mammals such as minks for their fur could make it easier for new viruses to cross over from the wild and spark fresh outbreaks.
Virologist Edward Holmes, who has led research into COVID-19, told AFP he felt that the global fur farming industry “is one most likely ways by which a new pandemic will start”.
“Personally, I think the fur farming industry globally should be closed down,” he added.
Holmes is a co-author of a new study looking at the potential danger posed by viruses in fur farms in the country where the first COVID-19 cases emerged in late 2019.
The Chinese-led team of researchers sequenced the genetic material from lung and intestine samples of 461 animals such as minks, rabbits, foxes and raccoon dogs that died from disease across the nation between 2021 and 2024.
Most were from fur farms, some were also farmed for food or traditional medicine, while around 50 were wild animals.
The team detected 125 viruses, including 36 new ones, according to the study in the journal Nature.
Thirty-nine of the viruses have a “high risk” of jumping across species, including to humans, the researchers evaluated.
Some of those viruses – such as hepatitis E and Japanese encephalitis – have already spread to humans, but 13 were new, the study said.
Several types of bird flu were also detected in guinea pigs, minks and muskrats.
And seven types of coronaviruses were also spotted – though none were closely related to SARS-CoV-2, which causes COVID-19.
