Mae’r mesur ar gadw adar dan do, a gafodd ei gyflwyno ym Mhrydain Fawr ym mis Rhagfyr fel un o nifer o fesurau i atal ffliw’r adar rhag lledaenu, wedi bod yn hanfodol i ddiogelu heidiau ledled y wlad rhag y clefyd sy’n cylchredeg mewn adar gwyllt.


Mae Llywodraeth Cymru, Defra a Llywodraeth yr Alban wedi bod yn cydweithio â’r diwydiant a cheidwaid adar i sicrhau bod mesurau bioddiogelwch llym yn cael eu dilyn ar safleoedd dofednod a’u cyffiniau er mwyn cadw heidiau’n ddiogel.  


Mae’r mesurau a ddefnyddiwyd wedi llwyddo i’n helpu i ffrwyno’r clefyd a chyn belled na fydd unrhyw achosion arwyddocaol newydd rhwng nawr a diwedd mis Mawrth, caiff y mesurau eu llacio.


Cadarnhawyd yr achos diwethaf mewn dofednod ym Mhrydain Fawr dros fis yn ôl ar 12 Chwefror yn yr Alban.  


Er bod y risg o ffliw’r adar wedi gostwng i ‘ganolig’, bydd y risg o weld achosion yn debygol o barhau am rai wythnosau eto.  Mae’r gofynion bioddiogelwch llymach a gyflwynwyd wrth gyhoeddi Parth Atal Ffliw’r Adar (AIPZ) ar 11 Tachwedd yn aros.


Bioddiogelwch da yw’r ffordd orau o hyd o reoli’r clefyd.  


Er ei bod yn hanfodol cadw mesurau bioddiogelwch effeithiol pan fydd y risg o ffliw’r adar ar gynnydd, rydym yn cynghori ceidwaid dofednod i gadw at y mesurau llymach bob amser i osgoi a ffrwyno achosion yn y dyfodol.  


Rydym yn cynghori ceidwaid adar i ddefnyddio’u hamser dros y bythefnos nesaf i baratoi’r mannau awyr agored ar gyfer eu hadar.  Dylai hynny gynnwys glanhau a diheintio arwynebau caled, codi ffens o gwmpas pyllau dŵr a merddwr ac ailgyflwyno mesurau i gadw adar gwyllt draw.


Hefyd, pan fydd yr adar yn cael mynd allan ddiwedd Mawrth, bydd dal gofyn i geidwaid dofednod ac adar caeth ddilyn mesurau fel glanhau a diheintio offer, dillad a cherbydau, gwahardd pobl nad ydyn nhw’n hanfodol rhag dod i’r safle a gofyn i weithwyr newid eu dillad a’u hesgidiau cyn mynd i’r mannau cadw adar.


Y cyngor yw bod y risg o straen H5N8 y feirws i iechyd pobl yn isel a’r risg o straeniau H5N2, H5N5 a H5N1 y feirws yn isel iawn. Mae’r asiantaethau safonau bwyd yn dweud mai isel iawn yw’r risg i gwsmeriaid bwyd yn y Deyrnas Unedig ac nad yw’n effeithio ar y rheini sy’n bwyta cynnyrch dofednod gan gynnwys wyau.


Mewn datganiad ar y cyd, dywedodd tri Phrif Swyddog Milfeddygol Prydain Fawr: 



> Bydd ceidwaid dofednod ym mhob un o’r gwledydd, ar ôl gweithio mor galed i gadw eu heidiau’n ddiogel dros y gaeaf, yn croesawu’r newyddion hyn.
> 
> 
> Rydym wedi cymryd camau buan i ffrwyno a dileu’r clefyd a rhaid i bawb sy’n cadw adar – p’un ai dyrnaid yn unig neu haid o filoedd – barhau i wneud eu rhan i gynnal y safonau bioddiogelwch ar eu safleoedd rhag i ni golli’r hyn a enillwyd dros y misoedd nesaf. Nid yw Risg Isel yn golygu Dim Risg.


Rydym yn cynghori pawb sy’n cadw dofednod ac adar caeth i gadw eu llygaid ar agor am arwyddion y clefyd ar eu hadar ac ar unrhyw adar gwyllt, ac i gysylltu â’u milfeddyg ar unwaith os oes ganddynt unrhyw bryderon.  Gallant ein helpu i gadw’r ffliw adar draw trwy ddilyn mesurau bioddiogelwch da, gan gynnwys:


  

•    Codi ffens o amgylch pyllau dŵr, nentydd, mannau gwlyb a merddwr a’u draenio os yw hynny’n bosibl  

•    Rhoi weiar netin neu orchudd dros byllau dŵr  

•    Cael gwared ar unrhyw fwyd y bydd adar gwyllt am ei fwyta  

•    Cadw adar gwyllt draw trwy gerdded yn rheolaidd trwy’r safle neu ddefnyddio modelau o adar ysglyfaethus  

•    Glanhau a diheintio concrit ac arwynebau caled eraill  

•    Rhoi naddion coed ar fannau gwlyb  

•    Cyfyngu ar nifer y bobl sy’n cael dod i’r safle  

•    Defnyddio cafnau i ddiheintio traed wrth ddod i’r safle a’i adael.


Os gwelan nhw adar gwyllt marw, dylai ceidwaid dofednod ac adar caeth ac aelodau’r cyhoedd ffonio llinell gymorth Defra ar 03459 33 55 77 (opsiwn 7\), ac os ydyn nhw’n credu bod y clefyd ar eu hadar, dylai ceidwaid ffonio APHA ar 0300 3038268 neu 03000 200 301 yn Lloegr.


Dylai ceidwaid dofednod gynefino â’r cyngor ar ffliw'r adar.

The housing measures, which were introduced across Great Britain in December as one of a range of measures to stop the spread of avian influenza, have been a vital tool in protecting flocks across the country from the disease which is circulating in wild birds.


Defra, the Scottish Government and Welsh Government have been working closely with industry and bird keepers to ensure that there are strict biosecurity measures in and around poultry premises to help keep flocks safe.


Measures put in place have been successful in helping to contain the disease and, provided that there are no new significant cases between now and the end of March, the current measures are due to be relaxed. The last confirmed case in poultry in Great Britain was over a month ago on 12 February in Scotland.


While the risk of bird flu has been reduced to ‘medium’, the risk of outbreaks is likely to persist for several weeks. As a result, enhanced biosecurity requirements that were brought in as part of the Avian Influenza Prevention Zone (AIPZ) on 11 November will remain in place. Good biosecurity is the most effective measure of disease control available.


While it is essential to ensure effective biosecurity when there is an increased risk of bird flu, it is advised that poultry keepers apply enhanced biosecurity measures at all times to prevent and mitigate future outbreaks.


Bird keepers are advised to use the next two weeks to prepare the ranges and outdoor areas for release of the birds. This will include cleansing and disinfection of hard surfaces, fencing off ponds or standing water and reintroduction of wild bird deterrents. 


In addition, when the birds are allowed out at the end of March all poultry and captive bird keepers will need to keep taking extra precautions, such as cleaning and disinfecting equipment, clothing and vehicles, limiting access to non\-essential people on their sites, and workers changing clothing and footwear before entering bird enclosures.


Public health advice is that the risk to human health from the H5N8 virus strain is low and from the H5N2, H5N5 and H5N1 virus strains is very low. Food standards bodies advise that avian influenza poses a very low food safety risk for UK consumers, and it does not affect the consumption of poultry products including eggs.  

In a joint statement Great Britain’s three Chief Veterinary Officers said:



> This will be welcome news for poultry keepers across the country who have put great effort into keeping their flocks safe this winter.
> 
> 
> We have taken swift action to contain and eliminate this disease and all bird keepers \- whether they have just a few birds or thousands \- must continue do their bit to maintain strict biosecurity measures on their premises so that we do not lose the progress that we have made over the past few months as Low risk does not mean No Risk.


Poultry and captive bird keepers are advised to be vigilant for any signs of disease in their birds and any wild birds, and seek prompt advice from their vet if they have any concerns. They can help prevent avian flu by maintaining good biosecurity on their premises, including:


* Fencing off ponds, streams, boggy areas or standing water and draining them where possible
* Netting or covering ponds
* Removing any wild bird feed sources
* Deterring wild birds by regularly walking through the area or by using predator decoys
* Cleansing and disinfecting concrete or other permeable areas
* Putting down wood shavings in wet areas
* Limit the number of people who come onto the site
* Use disinfectant foot dips when entering and exiting enclosures or houses


Poultry and captive bird keepers and members of the public should continue to report dead wild birds to the Defra helpline on 03459 33 55 77 (option 7\), and keepers should report suspicion of disease to APHA on 03000 200 301 and in Wales 0300 3038268\.


Poultry keepers should familiarise themselves with our avian flu advice.
