ANTHRAX UPDATE: Two Cows on Two Additional Colorado Premises Test Positive for Anthrax

August 15th, 2012

There has been two new confirmed cases of anthrax on two additional premises in Logan County. The new cases are located adjacent to the original case announced on August 8, 2012. No other livestock on the newly affected properties are showing clinical signs of the disease. Adjacent ranchers have been notified.

“This is not an uncommon occurrence with anthrax because adjacent properties may also contain the anthrax spores in the soil; we certainly hoped there wouldn’t be other herds affected but this is the nature of the disease,” said State Veterinarian, Dr. Keith Roehr. “We will expand our efforts onto the adjacent premises to protect the health of these cattle. At this time, all of the neighboring herds have been vaccinated for anthrax and affected herds are being treated.”

Anthrax vaccination is an important tool in preventing disease although full protective immunity is not achieved until 7-10 days after a second booster dose is administered.

While the Colorado Department of Agriculture (CDA) continues to monitor and remediate the situation with the livestock owners, the Northeast Colorado Health Department (CDHD) is performing its own public health investigation, ensuring that anyone at risk for a possible exposure to anthrax receives treatment.

NCHD has also been working with the Solid Waste Program at the Colorado Department of Public Health and Environment and CDA to ensure proper disposal of the animal carcasses. All of the infected carcasses have been incinerated; incineration kills anthrax spores and is the best means of disposal of the carcasses.

"At this point we really don't anticipate any health threat for the residents in northeast Colorado in regards to anthrax or from the smoke or plume from the incineration of the carcasses," said Dr. Cappello, the district public health administrator for the Northeast Colorado Health Department. "Anthrax is not spread person to person and anyone that has not had direct contact with infected cattle is not at risk of illness. We will continue to monitor the situation and follow up with those individuals that have been exposed through contact, but at this point there has been no human illness associated with this outbreak in cattle."
