Federal Response to HPAI in dairy Cattle
The US government is actively working to limit the spread of Highly Pathogenic Avian Influenza (HPAI) among cattle. A key component of this effort is requiring a negative Influenza A test for all lactating dairy cows moving across state lines. Any positive HPAI results must be reported to federal authorities immediately. As part of the National Milk Testing Strategy, milk samples are tested monthly for the H5N1 virus.
To date, over 24,000 milk samples have been examined nationwide, and all tests have returned negative results. the federal government is covering all costs associated with this testing program, including shipping and veterinary expenses.
Wisconsin’s Enhanced HPAI Regulations
Wisconsin is aligning with the federal guidelines but has implemented additional, stricter measures. Participation in livestock inspections and exhibitions within the state is contingent upon a recent negative HPAI test. This requirement will remain in place for 60 days following the last confirmed H5N1 detection in the United States.
Moreover, Wisconsin has established stringent health and identification requirements for any livestock imported from other states, aiming to prevent the introduction of the virus. Routine milk sampling from farms across Wisconsin is also being conducted as part of the national testing strategy.
Recognizing HPAI Symptoms and Advice for Dairy Farmers
Authorities report that HPAI typically does not cause high mortality rates in dairy cattle. Though, infection can lead to decreased milk production, reduced feed intake, and alterations in manure consistency. Given that these symptoms can also indicate other health issues, timely reporting and access to diagnostic testing are crucial.
Dairy farmers are strongly advised to isolate newly introduced animals, limit contact between animals, and remain vigilant for any abnormalities in milk production or appetite. Early detection and reporting are vital for effective control of the virus.
International Preparedness: The Netherlands
As of December 16, 2023, no cases of bird flu have been detected in dairy cattle in the Netherlands. Though, the country is proactively prepared with established protocols (a detailed playbook for avian influenza in dairy cattle) should the virus emerge. This proactive approach demonstrates a global awareness of the potential risks associated with HPAI and the importance of preparedness.
