Impact of #pH and #temperature in dairy #processing on the infectivity of #H5N1 avian #influenza viruses

Abstract Highly pathogenic avian influenza viruses (HPAIV) of subtype H5N1 (clade 2.3.4.4b) have crossed the species barrier and caused a mastitis-like infection in dairy cows . The high levels of infectious virus found in the milk raised considerable concerns about the safety of raw milk products . This study examined the effect of temperature and pH on the stability of HPAIV and low-pathogenic avian influenza viruses (LPAIV). We found that H5N1 HPAIV remained infectious in milk at 4 degrees Celsius for four weeks , with slow decreases at 21 degrees Celsius, and complete inactivation at 37 degrees Celsius after four weeks . H5N1 LPAIV was stable at 50 degrees Celsius for 30 minutes but inactivated at higher temperatures (55 degrees Celsius for 10 minutes, 60 degrees Celsius for 1 minute, or 72 degrees Celsius for 30 seconds). At pH levels between 6 and 10 , the virus remained stable but was partially inactivated at pH 5.0 and completely inactivated at pH 4.0. During yogurt production,...
