A disease related to naturally occurring anthrax is being blamed in the death of 13 animals on a Peace Region farm.
Anthrax is known to occur naturally on the Canadian prairies and in northern Alberta and can law dormant in soil for years.
The 13 confirmed livestock deaths all happened on a farm near Fort St John, and the anthrax spores themselves have been traced to a feeding site on the farm.
No further losses were reported on the farm and the remaining 150 animal herd will all be vaccinated to prevent the spread of the disease.
Public health officials have contacted any individuals who may have been affected by the spores and no further risk to humans is expected.
