Three Colorado Poultry Workers Presumed Positive for Bird Flu

Three poultry workers in Colorado are presumed to have contracted avian influenza after culling infected birds, potentially raising the number of U.S. human cases to seven since April. The CDC will confirm the cases and investigate the virus's transmission and mutation potential. The virus poses a low risk to the general public but has pandemic potential if it mutates to spread easily between people. The outbreak has affected millions of poultry and dairy herds across the U.S., with federal efforts underway to control it and develop vaccines. Properly cooked poultry and pasteurized milk remain safe to consume.
