Mae Prif Swyddog Milfeddygol Cymru'n cynghori pawb sy'n cadw dofednod yng Nghymru, o'r haid leiaf yn yr ardd gefn i'r fferm fasnachol fwyaf, i gadw golwg ar eu mesurau bioddiogelwch, i gofrestru ar gyfer rhybuddion a chofrestru'u hadar gyda'r Asiantaeth Iechyd Anifeiliaid a Phlanhigion (APHA). Mae hefyd yn atgoffa ceidwaid bod angen iddyn nhw roi gwybod i'w milfeddyg am unrhyw farwolaeth neu salwch anesboniadwy.
The Chief Veterinary Officer is advising all poultry keepers in Wales, from small backyard flocks to large commercial premises, to review their biosecurity, sign up for disease alerts and register their birds with the Animal and Plant Health Agency (APHA). Keepers are also reminded they must report any unexplained deaths or sickness to their vet.
