Another study demonstrating the effectiveness of pasteurization for the inactivation of avian influenza in dairy products has been published—this time, focused on dairy products other than milk. As the ongoing Highly Pathogenic Avian Influenza H5N1 (HPAI H5N1) outbreak continues to affect North American dairy herds, several studies have examined whether the virus poses a food safety risk in pasteurized milk. The science has shown that, although HPAI can be detected in cow’s milk, pasteurization inactivates the virus, rendering it non-infectious and therefore not a risk to public health. (Raw dairy, however, could potentially contain live HPAI H5N1 virus, and experts advise against consuming it).

Findings indicate that air ventilation systems could play a role in airborne transmission of the virus.

In late January, U.S. health officials announced that a new strain of avian flu, H5N9, was discovered on a duck farm in Merced County, California. They quarantined the farm and

A team of government veterinarians with the State Veterinary Institute Prague in the Czech Republic has found possible evidence of windborne H5N1 infections in chickens. In their paper posted on the bioRxiv preprint server, the group describes how chickens in a closed environment became infected with the H5N1 virus despite no contact with other chickens, wild birds, or their feces, leaving the wind as the only likely source.
