Outbreak of Avian Influenza in Texas and Kansas
In a concerning development, a mysterious illness has been detected in dairy cattle in Texas and Kansas. The U.S. Department of Agriculture (USDA) has confirmed that the illness is caused by the same strain of avian influenza that devastated millions of hens in 2022.

Identification of the Virus
The strain, known as highly pathogenic avian influenza Type A H5N1, has also been found in New Mexico. The USDA conducted tests on sick cattle at two dairy farms in Kansas and one in Texas, using clinical milk testing. Additionally, a second farm in Texas was identified with a swab test.
Origin of the Virus
It is believed that the virus was brought by wild migratory birds, as dead wild birds were found on the affected properties. Despite the presence of the virus, DNA testing did not show any mutations. The USDA has stated that the virus poses little risk to humans but can cause lethargy and reduced lactation in dairy cattle. While rarely fatal to cattle, it can be devastating to flocks of chickens.
Impact on the Industry
Between 2022 and 2023, the H5N1 strain caused the deaths of approximately 57 million chickens, leading to a significant decrease in egg and meat supplies. The outbreak resulted in substantial economic losses, with taxpayers footing a bill of around $757 million due to compensation fees to affected farmers.
Current Situation
The USDA Bird Flu Tracker has reported two recent detections of the virus in poultry flocks in Texas. One incident in Deaf Smith County affected 40 birds, while a larger flock in Moore County saw 280 birds impacted. The virus is highly contagious among various types of fowl, such as chickens, ducks, and turkeys.

Precautionary Measures
The USDA is urging ranchers to take necessary precautions, including sanitizing watering systems and preventing migratory birds from landing in standing bodies of water. Older cattle are deemed to be at the highest risk, and any symptoms should be reported promptly. Individuals handling dead wild birds are advised to wear gloves to prevent the virus from entering through the airways, eyes, nose, or mouth.
Human Transmission
While it is extremely rare for the virus to transmit to humans, one person was infected by a different strain of bird flu in April 2022. Fortunately, no cases of human infection have been reported with the current H5N1 strain. Globally, only 11 cases have been documented.
Assurance from USDA
The USDA has assured the public that there is no risk to the commercial milk supply or consumer health. Dairies are required to send only milk from healthy animals for processing, with milk from affected animals being diverted or destroyed. Additionally, pasteurization has been proven effective in deactivating bacteria and viruses like influenza in milk.
As the situation continues to unfold, it is essential for farmers and the public to remain vigilant and follow the guidelines set forth by the USDA to prevent further spread of the virus.
