Examining the Survival of A(H5N1) Influenza Virus in Thermised Whole Cow Milk
The recent spillover events of highly pathogenic avian influenza (HPAI) A(H5N1) clade 2.3.4.4b to dairy cattle, and high viral shedding in the milk from infected animals, has created concern that milk and dairy products could be a route for human infection. It has been demonstrated that pasteurization is effective in inactivating A(H5N1) in milk. However, multiple dairy products are made with unpasteurized but thermised milk. The aim of this study was to examine whether some conditions commonly used for thermisation are effective against inactivation of A(H5N1) in whole milk. For this purpose, we artificially inoculated whole raw cow milk with 6.5 log10 EID50 A(H5N1) and heated for 15 seconds at 60°C, 63°C and 66°C, the viral infectivity was tested using embryonated chicken eggs. We observed over 4 and 5 log10 reduction in viral infectivity at 60°C and 63°C, respectively. The viral infectivity was reduced to below the detection limit at 66°C. We also calculated the D-values, the time required to reduce the viral titer by one log10, for each treatment and as expected, we observed a decrease in D-values with increasing thermisation temperature. These data demonstrate that thermisation is effective in reducing the viral load and thus they allow for informed risk assessment of A(H5N1) contaminated dairy products made from thermized milk.

How do scientists know if individual wild birds are infected with avian influenza?
The U.S. Department of Agriculture implements a plan every year to monitor wild birds for highly pathogenic avian influenza. This national plan could not be implemented without the engagement of State partners, the National Flyway Council, the Department of the Interior, and other agencies. This coordinated effort is revised annually based on new science and data shared through the Interagency Steering Committee for Avian Influenza Surveillance in Wild Migratory Birds. Biological samples from hundreds of thousands of live-captured, apparently healthy wild birds; hunter-harvested birds; and dead wild birds contribute to these surveillance efforts. The USGS National Wildlife Health Center is USDA’s primary partner for testing sick and dead migratory birds for avian influenza.Learn more: USGS science on avian influenza
