Rwyf wedi gwneud y penderfyniad hwn ar sail tystiolaeth diweddaraf sydd wedi ei seilio yn ei dro ar Asesiad Risg Ansoddol, a oedd wedi ystyried y risg y gallai Ffliw Adar H5N8 gyrraedd ffermydd dofednod o ganlyniad, yn bennaf, i gysylltiad ag adar dŵr, ond hefyd drwy ffyrdd posibl eraill.
I have taken this decision based on the latest evidence, which is in turn based on a qualitative risk assessment, which considered the risk of incursion of H5N8 into poultry farms from contact primarily with resident wild waterfowl but also with other possible pathways.
