Anthrax has been found to be the cause of death of a cow southwest of Saskatoon.

The death on a farm in the rural municipality of Harris was confirmed by laboratory results Tuesday to be from the naturally-occurring bacteria.

Anthrax is also suspected in the deaths of two other animals.

Officials say anthrax spores can come to the surface after decades of inactivity, when land is excavated or there is a lot of runoff.

It's recommended that producers have their livestock vaccinated annually.

This is the second report of anthrax in Saskatchewan this year. Alberta also reported a case in cattle in the Fort Vermillion area this week.
