California Confirms More Avian Flu in Dairy Herds, Poultry

Sep 23, 2024

By Lisa Schnirring

The US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed 6 more H5N1 avian flu outbreaks in California dairy herds, raising the state's total to 16 since the virus was first found in the state's Central Valley dairy farms in the middle of August.

The detections push the national total of dairy farm outbreaks to 214 across 14 states.

In another avian flu development, the USDA confirmed highly pathogenic avian flu at a commercial turkey farm in California. The California Department of Food and Agriculture said the detection at the turkey farm is the state's first in domestic poultry since the state was declared free of the virus at the end of June.

Though Merced County is part of California's Central Valley, it's not clear if the turkey farm has any connection to the cattle outbreaks in that part of the state.

FDA advisers to discuss human H5 vaccines

Meanwhile, the Food and Drug Administration vaccine advisory group will discuss the composition of human H5 vaccines as part of preparedness for highly pathogenic as one of three topics at its upcoming meeting on October 10. The other topics on the Vaccines and Related Biological Products Advisory Committee (VRBPAC) agenda are recommendations on strain selection for seasonal flu vaccines for the Southern Hemisphere's 2025 season and research programs regarding departments that study viral diseases.

Video: Five Confirmed New World Screwworm Cases Raise Alarm for Livestock and Pet Owners

Pat Hoffmann, Swine Technical Consultant at Elanco Animal Health tells us about the impact of New World Screwworm. The emergence of New World screwworm in the U.S. creates a threat for veterinarians, livestock producers and pet owners that has not been seen north of the Florida Keys since the fly was eradicated from the United States more than 50 years ago. New World screwworm (Cochliomyia hominivorax) larvae feed on living tissue and can affect a wide range of warm-blooded animals, including livestock, companion animals, wildlife, and even humans.
“New World screwworm could have a devastating impact on animal health, welfare, and producer livelihoods,” said Jeff Simmons, President and CEO, Elanco Animal Health. “We want to thank the FDA, EPA and USDA, for all their work to prepare for this threat. We’re committed to supporting our customers during this challenging time by delivering innovation, scientific expertise, and available resources to help treat New World screwworm and support the health and well-being of animals.”
Elanco is working alongside the U.S. animal health industry to help them fight against this parasite, offering a portfolio of options for pets and livestock that can help treat New World screwworm larvae infestations.
