The U.S. Department of Agriculture (USDA) has confirmed the first case of Highly Pathogenic Avian Influenza (HPAI) H5N1 in a dairy cattle herd in Indiana. The detection was identified through routine testing carried out under the National Milk Testing Strategy and was not linked to pre-movement surveillance activities.
This marks an important development for the state's livestock sector. Since the HPAI outbreak began in March 2024, dairy cattle infections have been reported in multiple states across the country. Indiana now joins the list of states that have detected the virus in dairy herds.
Following the confirmation, the USDA’s Animal and Plant Health Inspection Service (APHIS) and the Indiana State Board of Animal Health are working together to conduct additional investigations. These efforts include on-farm inspections, diagnostic testing, and the collection of epidemiological data. The goal is to better understand how the virus was detected and to reduce the risk of further spread.
Officials have emphasized that the detection does not change the USDA’s current strategy for managing and controlling HPAI. Biosecurity remains one of the most important tools for preventing disease transmission between farms. Dairy producers are encouraged to strengthen protective measures and closely monitor their animals for signs of illness.
Livestock owners are also advised to report any unusual symptoms in cattle or unexpected cases of illness and death in wildlife to their state veterinarian. Early reporting can help authorities respond quickly and limit the spread of disease.
Despite the detection, federal officials have reassured consumers that there is no risk to the safety of the commercial milk supply. The U.S. Food and Drug Administration (FDA) states that pasteurization effectively inactivates the HPAI virus. As a result, commercially pasteurized milk remains safe for consumption.
In addition, dairy operations are required to send only milk from healthy animals for processing. Milk from affected animals is either diverted from commercial milk tanks or destroyed, preventing it from entering the human food supply.
According to public health officials, the risk to the general public remains low. The U.S. Centers for Disease Control and Prevention (CDC) continues to monitor the situation and advises that people who work closely with infected birds or mammals should follow recommended safety precautions.
The detection in Indiana highlights the importance of ongoing surveillance and strong biosecurity practices. Continued monitoring, cooperation among animal health agencies, and responsible farm management will play key roles in protecting both livestock and the agricultural industry from future disease spread.
