Cows at three dairy farms in California, USA test positive for H5N1 avian influenza virus

On August 30 local time, the California Department of Agriculture in the United States released news that cows at three dairy farms in the state tested positive for the H5N1 avian influenza virus, making California the 14th state in the United States where cows are infected with the avian influenza virus.

It is reported that California is the largest milk-producing state in the United States. The infected cows have shown symptoms since August 25. Currently, the infected cows have been isolated and are being treated on the farm. Healthy cows have been allowed to continue producing milk, and no human infection cases have been confirmed yet.

According to US federal data, since March, more than 190 herds and 13 workers in the United States have been infected with the avian influenza virus. Previously, avian influenza outbreaks have also occurred in poultry farms and other places in many parts of the United States, bringing a serious impact on the breeding industry.

Regarding the avian influenza epidemic at dairy farms in California this time, relevant departments said they are conducting further investigations and monitoring to determine the transmission route and potential risks of the virus. At the same time, measures are being taken to strengthen epidemic prevention management and monitoring of dairy farms to prevent the further spread of the epidemic.

The avian influenza virus will not only cause huge losses to the breeding industry but may also pose a threat to public health and safety. Therefore, the California Department of Agriculture and other relevant agencies attach great importance to this incident and actively take response measures to ensure the healthy development of the animal husbandry industry and the safety of the public. The international community is also closely watching the development trend of the avian influenza epidemic in the United States and the implementation effect of prevention and control measures.
