Yesterday, USDA confirmed the first case of H5N1 in swine was detected in Oregon. This farm is a small-scale farm that had pigs and poultry mingled together with access to shared feed, water, and shelter. This is separate from the avian influenza cases that were identified in commercial poultry flocks in Washington and Oregon earlier this month (those cases are believed to be originating from wild bird introduction).
More important for dairy operations, USDA also announced it will be expanding its H5N1 surveillance program for dairy operations. USDA has stated it will implement a multi-phased program in partnership with state veterinarians to collect bulk milk tank samples from farms on a regional and then state level to better assess the prevalence of H5N1 in dairy cattle. There are no additional details at this time, but Georgia Milk Producers staff is in communication with the State Veterinarian’s office.
Finally, Utah’s Department of Agriculture and Food confirmed highly pathogenic avian influenza in 8 commercial dairy facilities in Cache County. Utah becomes the 15th state to confirm H5N1 in dairy cattle.
