Cows in Texas and Kansas test positive for highly pathogenic bird flu
In a concerning development, wild migratory birds are suspected to have spread a deadly strain of bird flu to dairy cows in Texas and Kansas. This marks the first time that highly pathogenic avian influenza (HPAI) has been found in cows in the US.
The virus, identified as the Type A H5N1 strain, has been impacting bird populations globally. Previously, the HPAI virus was found in a young goat in Minnesota, marking the first time it was found in a domestic ruminant in the US.
Despite fears that the virus could adapt to spread widely in humans, the risk to the public is currently low. Genetic testing has indicated that the virus in cows is not more transmissible to humans. Milk samples from infected cows are being diverted and destroyed as a precautionary measure.
The virus is primarily affecting older cows, with symptoms including decreased milk production and low appetite. Sick cows have been reported in Kansas, Texas, and New Mexico.
The US Department of Agriculture (USDA) believes that the spread of H5N1 will not significantly affect milk production or herds, with little to no associated mortality. Officials are closely tracking the virus, and Texas officials have assured consumers that there is no threat to the public and no supply shortages are anticipated.
While the discovery of HPAI in cows is a cause for concern, authorities are working diligently to contain the spread and mitigate the potential impact on both animal and human health.
