What you need to know about H5N1 “bird flu” and your pets.
What is H5N1?
H5N1, commonly known as avian influenza A or bird flu, is a highly pathogenic strain of influenza virus that primarily affects birds, but cases have recently been reported in wildlife, cattle, cats, and humans.
What do we know about the latest outbreak?
Recently H5N1 influenza cases have been reported in cats that have consumed contaminated commercial raw food diets, unpasteurized milk, or had contact with wild birds and cattle.
Precautions:
Consider discontinuing your pet’s raw diet. Even if their raw food is human grade, frozen, or freeze dried, this does not prevent the potential spread of pathogenic bacteria, parasites, or H5N1 that may be present in the food. Consider cooking your pet’s raw food and/or consulting your veterinarian about diet change.
Limit your pet’s access to wild birds that may be carrying the virus and avoid giving them raw milk.
What are the symptoms to watch out for in our pets?
Clinical signs in pets may include the following:
• Loss of appetite
• Lethargy
• Fever
• Neurologic signs (ataxia, circling, tremors, seizures, sudden blindness)
• Copious oculonasal discharge
• Difficulty breathing
We recommend seeking veterinary care if your pet shows any of these signs. If they are having any life-threatening symptoms (neurologic signs, seizures, difficulty breathing, or collapse) seek veterinary care immediately.
Can this cause illness in humans?
Yes, H5N1 can cause illness in humans. Current human infections have been linked to contact with infected cattle and wild birds. There is no current evidence of human to human transmission.
What is being done?
The CDC, FDA and USDA are closely monitoring cases as they develop. One voluntary product recall has been issued for contaminated raw food diets for cats & dogs. We are continuing to monitor this emerging virus.
