The Nevada Department of Agriculture has detected Highly Pathogenic Avian Influenza in dairy cattle in Churchill County, according to a Friday news release.

The affected premises have been quarantined and mandatory testing will occur onsite until the herds are confirmed to be virus-free, the NDA said.

The first detection of HPAI in dairy cattle in Nevada was made in Nye County in December, the department said.

“Ensuring the safety of the industry is our utmost priority, and the NDA is working with industry members,” said NDA State Veterinarian Peter Rolfe. “It is critical that animal health biosecurity practices are enhanced to help prevent the spread of disease and protect animal and worker safety.”

The Centers for Disease Control maintains the risk to humans remains low, and the NDA is working with state and county health officials to protect human health and safety, the release said.

“Dairy and meat products remain safe for consumption. In addition, the USDA has determined that pasteurized milk will not transmit the virus to humans. Raw milk is illegal in Nevada,” said the NDA.

“As always, we recommend following food safety guidelines, only eating or drinking pasteurized milk and cheeses, and cooking meat to the appropriate minimum internal temperatures,” added Rolfe.

HPAI has been detected in dairy cattle in 16 states throughout the U.S. since March, the NDA said.

“Livestock owners are encouraged to practice good biosecurity and monitor animals for signs of illness. HPAI presents mild symptoms in cows, including reduced milk production, decreased feed consumption or coughing or sneezing. If an animal shows any signs of illness, contact your local veterinarian,” the release said. “Livestock workers should also monitor for symptoms, which may be mild, including fever, eye redness or irritation, or respiratory symptoms. Individuals showing signs of illness should seek medical attention.”
