A dairy worker in Michigan is the second person to test positive for the highly pathogenic avian influenza (HPAI) virus circulating in American dairy cow herds. The first case of human infection associated with this dairy herd infection of HPAI was detected in Texas in March.
The U.S. Centers for Disease Control and Prevention says symptoms of infection were mild for both cases and presented as conjunctivitis.
To date, 51 dairy herds in nine states have tested positive for the virus, according to the United States Department of Agriculture.
The Canadian Food Inspection Agency released an update today, May 23, outlining its testing of retail milk samples. No fragments of HPAI were found in any of the 303 samples tested from across Canada, CFIA says, adding that no cows have yet tested positive for the disease in Canada.
