Hypothesis
Domestic mink escaping from farms are a source of Aleutian disease virus (ADV) transmission to wild mink.
Conclusion
Mink farms act as sources of Aleutian disease transmission to wild mink, with higher seroprevalence in areas closer to farms.
Supporting Evidence
- Antibodies to Aleutian disease were detected in 29% of mink sampled.
- Seroprevalence was significantly higher in areas closer to mink farms.
- Hybrid mink had the highest seroprevalence at 44%.
- Distance from mink farms was the best predictor of AD seroprevalence.
Takeaway
Mink farms can spread a disease called Aleutian disease to wild mink, making them sick and possibly reducing their numbers.
Methodology
A large-scale serological survey across Ontario and a smaller-scale survey at the interface between a mink farm and wild mink were conducted.
Potential Biases
Potential bias from voluntary reporting and low sample submission rates from farms.
Limitations
The study may have biases due to low participation rates in voluntary testing and the inability to determine precise locations of some mink farms.
Participant Demographics
Free-ranging mink sampled across Ontario, with a mix of domestic, hybrid, and wild mink.
