On May 20, 2025 the Oregon Department of Agriculture issued emergency rules to mitigate the risk of transmission of highly pathogenic avian influenza (HPAI) and Rabbit Hemorrhagic Disease (RHD) at exhibitions. The purpose of the rules is to prevent the introduction of HPAI or RHD into an exhibition, while also providing a framework to mitigate the risk of transmission between livestock, and ultimately, to people if HPAI is introduced.
These rules apply only to exhibitions where "influenza susceptible animals" (lactating dairy cattle, swine, waterfowl, and other poultry) or rabbits will be present.
General Exhibition Requirements
Registration & Recordkeeping
Exhibitions where influenza susceptible animals or rabbits will be present must register with ODA at least 20 days prior to animals arriving at the exhibition (registration form included below).
Exhibition organizers will be required to collect and retain records of animals and exhibitors for 90 days following the exhibition. Records will only need to be made available to ODA in the case of a disease outbreak.
General Health Requirements
Exhibitions will be required to consult with a licensed veterinarians during the planning of the exhibition to ensure the protocols are in place to address animals that become sick during the exhibition, and exhibitions must have at least one veterinarian of record that is available to provide veterinary services during the exhibition.
Animals showing potential signs of infectious, contagious, or communicable diseases will not be allowed entry to exhibitions. Exhibitions must have a plan in place to isolate animals that develop potential signs of infectious, contagious, or communicable diseases during the exhibition until they can be examined by a veterinarian.
Different species of influenza susceptible animals (dairy cattle, swine, waterfowl, other poultry) must be housed separately at exhibitions, and may not be allowed to share unventilated confined airspace, fences, feeders, or waterers.
Exhibitions Open to the General Public
Exhibitions open to the general public must provide hand washing or sanitation stations at exits from areas where influenza susceptible animals are housed. Exhibitions must also provide signage regarding the risks of animal exposure and recommending hand washing at entrances and exits from areas where influenza susceptible animals are housed.
Handwashing signs for exhibitions will be available from CDC at the link below.
Species-Specific Requirements
Additional information on testing is available here.
Dairy Cattle Requirements
Lactating dairy cattle may not be milked in areas directly accessible to the general public. A physical separation (rope, wall, etc.) must be provided to keep members of the general public at least 10 feet away from animals while being milked.
Lactating dairy cattle must have a negative PCR test within 10 days prior to arrival at the exhibition, or originate from a farm currently participating in HPAI surveillance. ODA will provide supplies, shipping, and testing free of charge to exhibitors through the exhibition coordinators. Exhibitors must be an approved bovine HPAI sampler to collect samples.
Waterfowl Requirements
Waterfowl may not be provided open water to swim in while at exhibitions. Waterfowl must have a negative PCR test within 10 days prior to arrival at the exhibition, or originate from a flock certified free of HPAI under the National Poultry Improvement Plan. ODA will provide supplies, shipping, and testing free of charge to exhibitors through the exhibition coordinators.
