Anthrax found in Brown County cattle herd

Anthrax has been found in a Brown County cattle herd that also had the disease two years ago, officials said.
One animal died and the rest of the herd is vaccinated, said state Veterinarian Sam Holland.
The dead animal was a replacement heifer that had not been vaccinated yet this year.
The animal that died was in a pasture with about 50 other cattle, Holland said.
Anthrax spores occur naturally in the soil and can be dormant for decades. Drought, floods and wind can expose the spores for livestock to ingest while grazing.
