Saskatchewan Agriculture is reminding producers to be on the lookout for anthrax in their animals after confirmation that anthrax has been found in cattle in the RM of Harris #316.

Anthrax was confirmed by laboratory results on Dec. 17, as the cause of death in one cow.  It is the suspected cause of death of two other animals on the same farm.

This is the third report of anthrax in Saskatchewan this year.

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 the spores on pastures.  Spores can concentrate in sloughs and potholes, and 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.

Livestock are infected when they eat forage contaminated with spores.  Ruminants such as bison, cattle, sheep and goats are highly susceptible, and horses can also be infected.  Swine, birds and carnivores are more resistant to infection, but farm dogs and cats should be kept away from carcasses.

Affected animals are usually found dead without signs of illness.  Anthrax can be prevented by vaccination.  Producers in regions that have experienced previous outbreaks are encouraged to vaccinate their animals each year.

If your neighbours have anthrax, you should consider vaccination to protect your animals.  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.

Anyone who suspects anthrax should contact their local veterinarian immediately for diagnosis.  All tests must be confirmed by a laboratory diagnosis.  All positive test results Producers are advised to use caution when handling potentially infected animals or carcasses.  Animal cases pose minimal risk to humans but people can get infected through direct contact with sick animals or carcasses.

In cases where people believe they have been exposed to an infected animal, they should contact their local health authority or physician for advice.
