Animal Health Alert: H5 Bird Flu confirmed in three additional domestic cats in Los Angeles
County and in one commercially available raw pet food product.
1.13.2025
Key Points:
• Five indoor-only cats in one household experienced acute onset of illness after
consuming two brands of commercially available raw pet food. Four of the cats had
severe clinical signs and two of them died. One cat had mild clinical signs. One of the
severely affected cats was tested and later confirmed to be infected with H5N1 (aka H5
bird flu). Both raw pet food diets were tested, and one of the two raw pet foods,
Monarch Raw Pet Food, was confirmed to contain live, infective, H5N1 virus.
• In a second single-cat household, the indoor-only cat had acute onset of illness after
consuming three different brands of commercially available raw pet food. This cat was
tested and confirmed to be infected with H5 bird flu. The investigation is ongoing and
testing of the raw pet food by the US Food and Drug Administration (FDA) is currently
underway.
• Influenza A is rarely detected in cats. These are the first cats in LA County to be
confirmed positive for H5 bird flu after consuming raw pet food products.
• Five other cats from two different households in LA County have also been confirmed
with H5 bird flu after drinking raw milk for human consumption that was part of a recall
due to H5 bird flu contamination. All five of these cats died from H5 bird flu.
• H5 bird flu is a One Health issue that significantly affects human health, animal health
and the environment. Veterinarians should strongly advise pet owners to not consume
nor feed raw dairy, raw meat, raw poultry, and raw pet food diets to pets.
• REPORT suspected cases of H5 bird flu in cats and other animals. See the Guidance for
Veterinary Practices with Suspect H5 Bird Flu Cases in Pets. Influenza A testing is
available through commercial diagnostic laboratories. Testing through Public Health
may be available for certain cases. Take a complete dietary history (including any raw
dairy, raw poultry and/or meat including raw pet food diets, and wild bird exposure).
Dear Veterinary Colleagues
In Los Angeles County, there have now been 7 laboratory confirmed cases of H5 bird flu in cats. Five cats with confirmed H5 bird flu consumed raw milk that was part of a recall due to H5 bird flu contamination. Two cats with confirmed H5 bird flu consumed commercially available raw pet food products. There have been multiple H5 bird flu probable and suspected cases in cats that either consumed raw pet food or raw milk and became acutely ill, but not all cats were able to be tested.....

January 17, 2025: CDFA Has Confirmed New Cases of H5N1 Bird Flu in California Dairy Herds and Released 143 Fully Recovered Dairies from Quarantine
SACRAMENTO, CA — Following an investigation by the California Department of Food and Agriculture (CDFA) and rapid disease detection by California Animal Health and Food Safety Laboratory System (CAHFS), the U.S. Department of Agriculture's (USDA) National Veterinary Services Laboratories (NVSL) has confirmed H5N1 Bird Flu in 60 dairy farms in the last 30 days in California. Since California's first detection of H5N1 Bird Flu in dairies, there have been a total of 711 infected dairies with 143 of those affected, fully recovered and released from quarantine. All quarantine released dairies will be placed on a surveillance list for weekly testing through creameries to maintain continued monitoring of the virus in California.
Statewide Ban on all California Poultry and Dairy Cattle Exhibitions at Fairs and Shows
As the H5N1 Bird Flu virus continues to spread, our State Veterinarian placed a ban on poultry and dairy cattle exhibitions at fairs and shows on January 8, 2025, until further notice. This decision was made to protect California’s remaining unaffected dairy herds and poultry flocks across California. We’re working tirelessly to combat Bird Flu and protect our state’s farms and flocks. CDFA and USDA are working together to safeguard our agricultural resources and food supply. We hope our communities will support us in our efforts through support of this ban and to continue practicing enhanced biosecurity.
