Shamonda virus reaches cattle in Salzburg

The Shamonda virus has been detected in several cattle holdings in Salzburg, ORF reported. The disease is spreading among cattle in Austria and could cause farmers losses through reduced milk production and potential problems during calf births.

Affected cattle develop fever and, in particular, severe diarrhoea. The virus has been confirmed at individual farms in the Flachgau region of Salzburg.

Its actual spread is difficult to assess because the disease is not subject to mandatory reporting. Salzburg’s chief veterinary officer, Peter Schiefer, said the Agency for Health and Food Safety is currently examining samples from across Austria. Because all samples are sent to the agency’s laboratory, their geographic distribution can be tracked there, he said.

Authorities are currently focusing on protecting cattle from the carriers of the virus, small biting midges known as gnats. One measure is keeping the animals indoors during dawn and dusk.

The virus could also cause deformities in calves carried by infected cattle. Schiefer said the economic impact could be substantial, including losses from lower milk production and the cost of treatment. If deformities are confirmed, farmers could also face losses this winter.

Consumers have been reassured that milk and meat can be consumed without concern, according to Schiefer.
