Death of 200 Cows a Mystery to Wisconsin Officials

Officials in Wisconsin are investigating the death of 200 cows found on a Portage County farm. The owner of the cows said he was working with a local veterinarian who suspects that bovine rhinotracheitis or bovine virus diarrhea could have caused the mass deaths. No quarantine has been issued for the farm because there is no threat to humans, according to the Portage County Sherriff’s Department. Further tests are being conducted to determine the cause of the deaths. (Wausau Daily Herald). Read more.
