The H5N1 virus (also known as avian influenza A or H5) has been detected in the wastewater at the Goleta Sanitary District’s wastewater treatment plant.

The Goleta Sanitary District was notified of the finding at 3:04 p.m. Tuesday, Nov. 19.

This is the first time H5 has been detected at the plant, but it has been detected in numerous other counties in California, including recently in San Luis Obispo, according to the Sanitary District.

Goleta Sanitary District participates in wastewater testing via a group called Cal-SuWers under the California Department of Public Health.

The testing program was created following the outbreak of SARS-CoV2 (Covid-19). In an effort to monitor viral loads in wastewater as a proactive measure to identify outbreaks before they escalate, testing is being performed statewide for the presence of viruses including the flu, respiratory illnesses, and recently the H5 virus.

Due to the method of sample collection and analysis, the source of H5 cannot be determined at this time, but Goleta Sanitary District staff are tracking any identified detections in an attempt to gather more information, the district reports.

The source could be animal or human in nature, the district said.

The Goleta Sanitary District said it is committed to working with the California Department of Public Health and the CDC in monitoring the results and will keep the public informed.

In the meantime, the public is urged to follow the following practices:

Avoid exposures to sick or dead animals, including wild birds, poultry, or other domesticated birds, and other wild or domesticated animals (including cows) if possible.

Avoid exposures to animal feces, bedding (litter), unpasteurized (“raw”) milk, or materials that have been touched by, or are close to birds, or other animals with suspected or confirmed avian influenza A (H5N1), if possible.

People should not drink raw milk. Pasteurization kills avian influenza A (H5N1) viruses, and pasteurized milk is safe to drink.

People who have job-related contact with infected or potentially infected birds or other animals should be aware of the risk of exposure to avian influenza viruses and should take proper precautions. People should wear appropriate and recommended personal protective equipment when exposed to an infected or potentially infected animal(s).

According to officials, across California, as of July 11, there is no indication that H5 detections in wastewater are associated with human-to-human transmissions of H5.
