According to the agency, the severe Eurasian avian flu, designated HPAI H5N1, was identified in two sick geese from the Perris area. They were impounded by the Department of Animal Services last week and humanely euthanized due to their advanced decline, departmental spokesman John Welsh said. He said afterward, they were sent to a lab for testing, which on Tuesday reflected that they had been infected. https://nbcpalmsprings.com/2022/10/20/first-cases-of-avian-flu-confirmed-in-riverside-county/
