San Diego County public health officials have issued a warning to residents about the risks associated with consuming raw milk products due to the potential presence of H5N1, commonly known as bird flu. The concern arises because raw milk and its derivatives are not pasteurized, leaving them susceptible to containing harmful pathogens such as H5N1, salmonella, E. coli, and listeria. These pathogens can lead to severe illnesses and may pose a significant threat to immunocompromised individuals, young children, and pregnant women.

The advisory also includes caution against pet products that contain raw milk. Pets like dogs and cats are at risk if these products harbor dangerous bacteria or viruses. Furthermore, pet owners are advised to keep their animals away from sick or deceased birds outdoors. The Los Angeles County Department of Public Health has already confirmed two cases of H5 bird flu in cats linked to recalled raw milk from Raw Farm, LLC.

Pasteurization is highlighted as an effective heat treatment process that ensures the safety of dairy products by eliminating bacteria and other pathogens without altering the product's nature.

Prior incidents in San Diego County have connected illnesses to raw milk consumption even before bird flu became prevalent in California. In 2023, several salmonella cases were reported following the consumption of raw milk from a Fresno-based producer.

In response to the situation, California Governor Gavin Newsom declared a State of Emergency earlier this week to bolster efforts against bird flu. The California Department of Public Health has documented 34 human cases statewide but maintains that the current risk level for the general public is low.

H5N1 is noted for its high contagion rate among birds and other animals; it can occasionally infect humans through contact with contaminated eyes, nose, mouth, or inhalation.

San Diego County Public Health Services continues monitoring H5N1 developments alongside federal and state health partners while engaging with local veterinarians and healthcare providers. As yet, no human cases have been reported within San Diego County itself.

Individuals most vulnerable include farm workers or those dealing with wildlife who might come into contact with infected animals. Personal protective equipment has been made available by the county for eligible farms, wildlife organizations, and animal control personnel. Although seasonal influenza vaccines do not offer protection against bird flu specifically, vaccinations are encouraged to mitigate serious illness risks overall.
