Dairy cow disease tied to HPAI
USDA says a small number of dairy herds in Texas and Kansas tested positive for a strain of highly pathogenic avian influenza (HPAI). To date, three dairies in Texas and one in Kansas have tested positive. Federal and state agencies are moving quickly to conduct additional testing for HPAI, as well as viral genome sequencing, so that we can better understand the situation, including characterization of the HPAI strain or strains associated with these detections.
USDA’s Animal and Plant Health Inspection Service (APHIS) says the virus is carried by wild waterfowl, which experts think is how the illness is spreading. Even with the diagnosis, USDA is still not recommending herd depopulation or movement restrictions of animals.
USDA noted, “At this stage, there is no concern about the safety of the commercial milk supply or that this circumstance poses a risk to consumer health. Dairies are required to send only milk from healthy animals into processing for human consumption; milk from impacted animals is being diverted or destroyed so that it does not enter the food supply. In addition, pasteurization has continually proven to inactivate bacteria and viruses, like influenza, in milk. Pasteurization is required for any milk entering interstate commerce.”
Federal agencies are also working with state and industry partners to encourage farmers and veterinarians to report cattle illnesses quickly so that we can monitor potential additional cases and minimize the impact to farmers, consumers and other animals.
