Livestock producers are being warned to take precautions after a case of animal anthrax turned up in a rural municipality in Saskatchewan.
According to the Ministry of Agriculture, anthrax has been found in the RM of Cote in eastern Saskatchewan and its presence was confirmed by lab testing on Monday. The disease was responsible for the death of one cow, and is suspected to be behind two more deaths from the same herd.
Anthrax, the ministry explained, is caused by a bacteria that can survive as a spore in soil for decades, where it can build up in sloughs or potholes over time. That puts animals at risk of exposure, particularly in drier years when more areas become accessible.
“Spores can also surface when the ground is excavated or when there is excessive run-off,” the ministry added.
Livestock that consume the spores along with their forage can become infected, with ruminant animals like cattle, bison, sheep and goats all highly susceptible, as are horses.
“Swine, birds and carnivores are more resistant to infection, but farm dogs and cats should be kept away from carcasses,” the ministry noted.
Animals affected by anthrax are usually found dead without any signs of illness, the ministry said, but anthrax infection can be prevented through vaccination.
Producers in areas where previous outbreaks have occurred are being strongly encouraged to vaccinate their animals annually, the ministry said, and any producers whose neighbours have seen anthrax cases should also consider vaccinations.
“The carcasses of any animal suspected of having anthrax should not be moved or disturbed and should be protected from scavengers such as coyotes or ravens, to prevent spreading spores in the environment,” the ministry said.
“Anyone who suspects anthrax should contact their local veterinarian immediately for diagnosis.”
Livestock producers were also cautioned to use extra care when handling any animals or carcasses that could be infected by anthrax, as there’s a small chance the infection could transfer to a human.
“Animal cases pose minimal risk to humans, but people can get infected through direct contact with sick animals or carcasses,” the ministry said.
“In cases where people believe they have been exposed to an infected animal, they should contact their local health authority or physician for advice.”
