DOVER, Del. – Delaware Department of Agriculture officials have announced the state’s first presumptive positive H5 Avian Influenza case of 2025.

We’re told the preliminary testing of a commercial broiler flock in Kent County has returned a presumptive positive H5 from the University of Delaware’s Lasher Laboratory in Georgetown. Additional samples have been sent to the USDA’s National Veterinary Services Laboratory for further confirmation.

State officials have quarantined the affected premises and the birds on the property are reportedly being depopulated to prevent the spread of the disease. Birds from the block will not enter the food system.
