Anthrax was confirmed by laboratory results on Tuesday as the cause of death in cattle in the R.M. of Paynton No. 470, the Saskatchewan Ministry of Agriculture confirmed in a news release Wednesday afternoon.
Dr. Wendy Wilkins, a Disease Surveillance Veterinarian with the Ministry of Agriculture, said in an email to media there are two confirmed deaths on one farm while the rest of the herd is being treated and vaccinated, but doesn’t “expect to see any additional anthrax-related deaths in this herd.”
All tests must be confirmed by a laboratory diagnosis and all positive test results must be reported to the provincial Chief Veterinary Officer, according the Ag Ministry.
Saskatchewan Agriculture explains “anthrax is caused by the bacteria Bacillus anthracis, which can survive in spore form for decades in soil. Changes in soil moisture, from flooding and drying, can lead to a build-up of spores on pastures. Spores can concentrate in sloughs and potholes, and the risk of animal exposure to anthrax increases in drier years when these areas dry up and become accessible. Spores can also surface when the ground is excavated or when there is excessive run-off.”
Bison, cattle, sheep, goats are highly susceptible to Anthrax and horses can also get infected; pigs, birds, and any carnivore animal are more resistant to infection, but farm dogs and cats should be kept away from carcasses to limit the risk of exposure. Livestock can get infected by eating forage contaminated with spores.
While animal cases of anthrax pose minimal risk to humans, people can still get infected through direct contact with sick animals or carcasses.
Vaccination is the best way to prevent anthrax, the Ministry says, and livestock producers, especially those in regions where previous outbreaks have occurred, are strongly encouraged to vaccinate their animals each year.
Anyone who suspects anthrax in their livestock to contact their local veterinarian immediately for diagnosis, or their physician if they believe individuals have been exposed to an infected animal.
Producers are also advised to not move or disturb the carcass of any animal suspected of having anthrax to prevent the spread of spores, as well as protect it from scavengers such as coyotes or ravens.
