Canadian officials monitoring avian flu on dairy farms after first-ever case detected in U.S. cows

After cases of avian flu were found in dairy cattle in eight U.S. states, Canada’s agricultural industry is taking steps to monitor its herds.According to the U.S. Centers for Disease Control and Prevention, the highly pathogenic H5N1 virus has been detected in cows, marking the first time that avian flu has infected bovines. Earlier this month – in likely the first instance of mammal-to-human transmission of the virus – a dairy worker in Texas was diagnosed with the bird flu after having contact with cattle and was presumed to be infected.
