State agricultural officials have identified two other flocks of backyard birds infected with bird flu.
The Department of Agriculture said Tuesday they are in Deschutes County, marking the fifth and sixth outbreaks of the disease there. This coincided with the death of nine pet rabbits as a result of a virus that affects rabbits and hares only, but is spread by other organisms.
State agriculture officials said Oregon has had 11 cases of bird flu in non-commercial backyard flocks this year: six in Deschutes County, two in Lynn County and one each in Polk, Lynn and Cos County. The latter was announced last week.
Either way, agriculture officials culled the flocks to prevent the spread of the deadly virus. They have euthanized 1,330 birds, including about 150 ducks, chickens and peas in the last two cases.
Since the first outbreaks appeared in Deschutes County, it has been under quarantine.
“Quarantine applies to all poultry and poultry products in the quarantine zone,” department spokeswoman Liz Beale said. Poultry or poultry products may not be removed from a farm within a quarantine area unless they are disposed of in an approved manner (landfill, or DEQ permitted disposal site).
The recent outbreak will not expand the quarantine because the owners have not sold eggs or other poultry products. State officials said the federal guidelines would have required an expansion had that been the case.
State officials have said that the outbreak of HPAI or highly pathogenic avian influenza does not pose a public health threat. Avian influenza does not affect poultry meat or egg products, which are considered safe to eat provided they are prepared safely and adequately cooked.
The virus is usually spread by migratory birds but some groups of wild waterfowl live in Oregon during the summer and year-round.
“It appears that these populations carry highly pathogenic avian influenza, and when they are given opportunities to interact directly with domestic poultry, we see transmission of the highly pathogenic avian influenza virus to those domestic birds,” Bell said. “High virulence avian influenza is extremely deadly to most species of domestic poultry, but ducks (boiled and inland) are unique in that they can contract the highly pathogenic avian influenza virus, but not develop any symptoms or die from it.”
Infected poultry can also spread the virus for a short time.
Symptoms include sudden death, lethargy, lack of appetite and coordination, purple discoloration or swelling of body parts, diarrhea, coughing and sneezing. It can reduce egg production and cause abnormal eggs.
A statement from state veterinarian Ryan Schultz said he expects more outbreaks as fall approaches and the birds begin their winter migrations.
State officials advise backyard herd owners to be vigilant about biosecurity and surveillance. “Preventing any contact between wild birds and domestic flocks is the best way to protect domestic birds from highly pathogenic avian influenza,” the department said.
The Ministry of Agriculture will continue to update the public. Starting August 8, everything will be posted Confirmed cases of bird flu in Oregon on the Internet. The audience can Participation To receive updates via email.
Viral disease affects rabbits in Oregon
State officials said two pet rabbits in one home in Linn County have died after contracting a deadly virus that only affects rabbits and hares.
State officials said one rabbit “was lethargic, refused to eat, and then experienced convulsions shortly before his death last Friday, state officials said. Later that day, another rabbit died in the house,” state officials said. .
The veterinary laboratory at Oregon State University confirmed that the rabbits died of rabbit hemorrhagic disease type 2, or RHDV2, a highly contagious virus that can spread rapidly between rabbits and rabbits. It does not pose any danger to humans.
A week ago, seven pet rabbits in Multnomah County were infected with the virus and diet.
The virus is resistant to extreme temperatures and can exist in the environment for months. It is spread through direct contact with an infected rabbit or contaminated material. Birds, rodents, flies, predators, and litter can spread the virus through their feet, fur, feathers, or feces without becoming infected.
In the case of Lane County, wild rabbits live close to the house, and the owner’s cat goes outside and also spends time with the pet rabbit.
The state has asked the public to report the rabbit deaths so they can track the spread of the virus.
