Fur farms can bring large numbers of susceptible animals into close contact, creating conditions where infectious diseases can spread rapidly.
Between December 2020 and May 2021, three mink farms in British Columbia experienced SARS-CoV-2 outbreaks. Genetic analysis linked infections among mink and farm workers, showing that mink farms can become sites of cross-species transmission (Paiero et al., 2022).
Researchers later investigated whether infected farmed mink could come into contact with wildlife outside the farms. Around the three affected farms, 71 animals from nine species were sampled. Three escaped domestic mink tested positive for SARS-CoV-2, while the other 68 sampled wild animals tested negative (Strang et al., 2022).
The study did not confirm infection in a free-living wild animal that did not originate from a farm. However, it demonstrated that infected farm animals had moved outside confinement and could potentially come into contact with wildlife (Strang et al., 2022).
Canadian guidance has also identified manure and composted carcasses as possible pathways for the spread of Aleutian mink disease virus between farms and wild mustelids (Community for Emerging and Zoonotic Diseases).
Together, these findings highlight how fur farms are interconnected with the surrounding environment and wildlife. While Canadian evidence does not establish that SARS-CoV-2 spread from farms into wild animal populations, it shows how animals and materials associated with farms can extend beyond their boundaries.
