HPAI Notice

The Maine state veterinarian has asked that UMaine Extension encourage any bird owner with possible avian flu (HPAI) cases (sudden deaths, unexplained severely ill birds) to call this hotline number:  866.536.7593.

If poultry are ill or have died, but the onset of symptoms was slower, or the owner suspects Marek’s disease or other non-HPAI cause of loss, then they are encouraged to contact our Veterinary Diagnostic Laboratory at 207.581.3874.
