The Los Angeles County Department of Public Health is monitoring the ongoing multi-state outbreak of H5N1 bird flu in wild birds, poultry, and U.S. dairy cows. Public Health monitors and tests symptomatic birds, pets, and wild mammals in LA County for H5N1 through our Public Health Laboratory.
In January 2024, one local case of avian flu was confirmed in a Western Gull found in Manhattan Beach. No illnesses were reported in residents who had contact with the gull. There are no known cases of H5N1 in California cows based on the limited testing being conducted by veterinarians. Testing of lactating dairy cattle is required when they are transported across state lines and the USDA is now providing financial support to dairies where cattle are positive for H5N1 influenza.
While the risk of transmission to LA County residents is low, Public Health encourages resident to follow these best practices when around animals or when consuming animal products:
For questions or to find a nearby clinic or doctor, residents can call the Public Health InfoLine at 833-540-0473. Open every day from 8 a.m. to 8 p.m.
