As of today (6 November) the risk level of avian influenza incursion in wild birds in Great Britain has been raised from ‘medium to ‘high’ following two unrelated confirmed cases in England this week and increasing reports of the disease affecting flocks in mainland Europe. 


All bird keepers are being urged to prevent direct or indirect contact with wild birds, with the risk of infection of poultry in Great Britain also being raised from ‘low’ to ‘medium’. Wild birds migrating to the UK from mainland Europe during the winter period can spread the disease to poultry and other captive birds.


Northern Ireland’s risk of avian influenza incursion remains medium for wild birds and low for poultry, but is being kept under constant review.


 A statement from the UK’s four Chief Veterinary Officers said:



> “Following two confirmed cases of avian influenza in England and further cases reported in mainland Europe, we have raised the risk level for incursion to Great Britain from migratory birds to high. We have also raised the risk level for the disease being introduced to poultry farms in Great Britain to medium. While Northern Ireland’s risk level is currently medium for wild birds and low for poultry, the situation is being kept under constant review.  
> 
>   
> 
> “We have acted quickly to prevent the spread of disease at both sites in England and are continuing to monitor the situation closely. Bird keepers should remain alert for any signs of disease and report suspected disease immediately.  
> 
>   
> 
> “It is important now more than ever that bird keepers ensure they are doing all they can to maintain and strengthen good biosecurity on their premises to ensure we prevent further outbreaks.”


The UK has robust biosecurity measures and monitoring in place to prevent the disease spreading in this country and the risk of transmission of avian influenza viruses to the general public in the UK remains very low.  

There are some simple measures that all bird keepers, whether they are running a large commercial farm, keeping a few hens in their back garden, or rearing game birds, should take to protect their birds against the threat of avian flu in the coming winter months.


These include:


* Keeping the area where birds live clean and tidy, controlling rats and mice and regularly cleansing and disinfecting any hard surfaces
* Cleaning footwear before and after visits
* Placing birds’ feed and water in fully enclosed areas that are protected from wild birds, and removing any spilled feed regularly
* Putting fencing around outdoor areas where birds are allowed and limiting their access to ponds or areas visited by wild waterfowl
* Where possible, avoid keeping ducks and geese with other poultry species.
* The Government continues to monitor for incursions of avian flu and is working with the poultry and game bird industries; hen rehoming and pure and traditional poultry breeds stakeholders to help reduce the risk of disease.

Daw’r alwad wrth i’r pedwar Prif Filfeddyg godi heddiw (6 Tachwedd) lefel y risg y gallai adar gwyllt ddod â ffliw’r adar i Brydain Fawr o ‘ganolig’ i ‘uchel’ yn sgil cadarnhau dau achos digyswllt yn Lloegr yr wythnos hon a chynnydd yn nifer yr achosion o’r clefyd mewn heidiau ar dir mawr Ewrop.


Mae pob ceidwad adar yn cael ei annog i amddiffyn ei adar rhag dod i gysylltiad uniongyrchol neu anuniongyrchol ag adar gwyllt ac mae lefel y risg o heintio dofednod ym Mhrydain Fawr hefyd wedi’i chodi o ‘isel i ‘ganolig’. Mae adar gwyllt sy’n mudo i’r DU o dir mawr Ewrop yn y gaeaf yn gallu cario’r clefyd i ddofednod ac adar caeth eraill.


Mae lefel y risg y gallai adar gwyllt ddod â ffliw’r adar i Ogledd Iwerddon yn parhau’n ‘ganolig’ a’r risg o heintio dofednod yn parhau’n ‘isel’. Ond byddwn yn cadw golwg ar y sefyllfa.


Dywed pedwar Prif Swyddog Milfeddygol y DU mewn datganiad:



> “Ar ôl cadarnhau dau achos o ffliw’r adar yn Lloegr ac achosion eraill ar dir mawr Ewrop, rydym wedi codi lefel y risg y gallai adar mudol ddod â ffliw’r adar i Brydain Fawr i ‘uchel’. Rydym hefyd wedi codi lefel y risg y gallai’r clefyd gael ei gario i ffermydd dofednod ym Mhrydain Fawr i ‘ganolig’. Er bod lefel y risg yng Ngogledd Iwerddon ar gyfer adar gwyllt yn ganolig ac yn isel ar gyfer dofednod, rydym yn cadw golwg ar y sefyllfa.

> 
> “Rydym wedi gweithredu’n gyflym i rwystro’r clefyd ar y ddau safle yn Lloegr rhag lledaenu ac rydym yn cadw golwg glos ar y sefyllfa. Dylai ceidwaid adar gadw’n effro am unrhyw arwyddion o’r clefyd a’n hysbysu ar unwaith os oes ganddynt unrhyw amheuon.

> “Mae’n bwysicach nawr nag erioed bod ceidwaid adar yn sicrhau eu bod yn gwneud popeth yn eu gallu i gynnal a chryfhau mesurau bioddiogelwch ar eu ffermydd i osgoi unrhyw achosion pellach.”


Mae gan y DU fesurau bioddiogelwch a monitro i rwystro’r clefyd rhag lledaenu yn y wlad hon ac mae’r risg o drosglwyddo feirysau ffliw’r adar i’r cyhoedd yn y DU yn parhau’n isel iawn.


Mae yna nifer o fesurau syml y dylai pawb sy’n cadw adar, boed ychydig o ieir yn yr ardd gefn neu adar ar gyfer eu hela neu ar fferm fasnachol fawr, eu cymryd i ddiogelu’u hadar rhag ffliw’r adar dros fisoedd y gaeaf.


Sef:


* Cadw’r lle rydych yn cadw’ch adar yn lân ac yn dwt, gan reoli llygod mawr a bach a glanhau a diheintio arwynebau caled yn rheolaidd
* Glanhau esgidiau cyn ac ar ôl ymweliadau
* Gosod bwyd a dŵr yr adar mewn mannau caeedig, wedi’u diogelu rhag adar gwyllt, a chymhennu’n rheolaidd unrhyw fwyd sydd wedi sarnu
* Codi ffens o gwmpas y rhannau awyr agored y mae’r adar yn cael mynd iddynt, a’u rhwystro rhag mynd i byllau dŵr a mannau eraill y mae hwyaid a gwyddau gwyllt yn cael mynd atynt.
* Lle medrwch, peidiwch â chadw hwyaid a gwyddau gyda dofednod eraill.
* Mae’r Llywodraeth yn parhau i gadw golwg am achosion o ffliw’r adar ac mae’n gweithio gyda’r diwydiannau dofednod ac adar hela a chymdeithasau ailgartrefu ieir a chymdeithasau bridiau traddodiadol i’w helpu i leihau’r risg o ddal y clefyd.
