Naturally occurring anthrax kills livestock near Fort St. John

A diagnosis of naturally-acquired anthrax has been confirmed in the death of 13 livestock on a farm near Fort St. John.

The animals are thought to have contracted the disease from exposure to dormant anthrax spores in the soil of a feeding site, which is no longer being used. No further losses on the farm, which has a herd of more than 150 animals, have been reported.

Anthrax occurs naturally in livestock on the Canadian Prairies and in Northern Alberta, and is established in Alberta’s Wood Buffalo National Park. The bacteria can remain dormant in soil under certain conditions for many years.

An effective vaccine for anthrax for livestock is available and the rest of the herd on the infected farm will be vaccinated. Animals that have been exposed to anthrax spores in soil are often successfully treated if diagnosed early. Livestock producers seeking advice on the prevention, diagnosis and treatment of anthrax cases in their herd are encouraged to contact their veterinarian.

Though anthrax can affect humans, infection is very rare and there have been no indications of anyone in contact with the animals being infected. Public health officials have identified individuals who might have been in contact with the source of infection, and are following up with those individuals directly to assess their health and provide health advice. There is no health risk to the general public.

People handling infected animals or contaminated products may contact anthrax spores through cuts or scrapes on their skin, resulting in sores and infection that can be treated with antibiotics.
