The U.S. Department of Agriculture and Oregon state veterinary officials have confirmed a case of H5N1 in swine. The farm in Oregon is a backyard operation, with a mix of poultry and livestock, including swine.
The swine were tested following detection in the poultry flock, the swine were not reportedly exhibiting symptoms. The livestock and poultry on this farm shared water sources and housing, which may have created the opportunity for transmission between species. The farm has been quarantined to prevent further spread of the virus.
Per USDA, this farm is a non-commercial operation, and the animals were not intended for the commercial food supply. USDA has affirmed that there is no concern about the safety of the nation’s pork supply as a result of this finding. The Food and Drug Administration and USDA continue to emphasize that the commercial milk supply is safe because of the pasteurization process. USDA is also confident that the meat supply is safe.
