Avian influenza is a highly contagious viral disease affecting the respiratory, digestive and/or nervous system of many species of birds. It spreads from bird to bird by direct contact with infected body fluids, droppings and contaminated boots, clothing, equipment etc.  
  
Reports of Avian Influenza H5N8 outbreaks in wild birds and poultry in Germany, Austria, Croatia, Denmark, Hungary, Netherlands, Poland and Switzerland have resulted in the risk level for Avian Influenza incursion to the UK via wild birds being raised from “Low” to ‘Medium’.   
  
Poultry keepers are advised to monitor their birds frequently and to discuss any concerns with their private vet immediately.  Employing good biosecurity practices will serve to minimise opportunities for disease incursion and spread, these include:  


* thorough cleansing and disinfection of clothing, equipment and vehicles before and after their use,
* thorough cleansing and disinfection of housing at the end of each production cycle,
* ensuring that feed and food stores are covered and minimising other opportunities for direct and indirect contact with wild birds,
* limiting the number of visitors on to your premises and for those that do, ensure that they understand and adhere to your biosecurity requirements, these should be reviewed and updated regularly,
* having disinfectant available at your farm entrances for those entering and leaving to use.

The Cabinet Secretary for Environment and Rural Affairs, Lesley Griffiths, said:   

> “It’s important all poultry keepers remain vigilant for signs of disease in their flock and maintain levels of biosecurity to minimise the risk of any disease spread. 
> 
> “Good communication is also vital for disease control and I urge all poultry keepers to notify or update their details and those of their flocks on the poultry register. This will ensure they can be contacted immediately in an avian disease outbreak, allowing them to take action to protect their flock at the earliest opportunity.”

The Chief Veterinary Officer for Wales, Christianne Glossop, said:


> “Whilst none of the cases of Avian Influenza to date have been located in the UK, poultry keepers need to closely monitor their flocks for any signs of disease. In particular respiratory distress, diarrhoea, fewer eggs being laid, loss of appetite and discolouration of neck and throat.  Avian Influenza is a notifiable disease, and so any suspicion should be reported immediately.
> 
> “All poultry keepers should also continue their efforts to maintain high levels of biosecurity to minimise contact between their own flocks and wild birds.”

Mae Ffliw’r Adar yn glefyd firysol hynod heintus sy’n cael effaith ar system anadlol, dreulio ac/neu nerfol nifer o rywogaethau adar.  Mae’n lledaenu o un aderyn i’r llall trwy gysylltiad uniongyrchol â hylifoedd heintus, baw adar, ac esgidiau, dillad ac offer wedi’u heintio.    
  
Mae adroddiadau o achosion o Ffliw’r Adar H5N8 mewn adar gwyllt a dofednod yn yr Almaen, Awstria, Croatia, Denmarc, Hwngari, yr Iseldiroedd, Poland a’r Swistir wedi arwain at godi lefel y risg o Ffliw’r Adar yn dod i’r DU drwy adar gwylltion o “Isel” i “Canolig”.    
  
Awgrymir i geidwaid dofednod fonitro eu hadar yn rheolaidd ac i drafod unrhyw bryderon gyda’u milfeddyg preifat ar unwaith.  Byddai defnyddio arferion bioddiogelwch da yn helpu i’w wneud yn llai tebygol i’r clefyd godi a lledaenu, ac mae’r rhain yn cynnwys:    


* glanhau a diheintio dillad, offer a cherbydau cyn ac wedi eu defnyddio,
* glanhau a diheintio llochesi adar ar ddiwedd pob cylch cynhyrchu,
* sicrhau bod storfeydd porthiant a bwyd wedi’u gorchuddio a lleihau unrhyw gyfleoedd eraill o gysylltiad uniongyrchol gydag adar gwyllt,
* lleihau nifer yr ymwelwyr â’ch eiddo, ac i’r rhai sydd yn ymweld, sicrhau eu bod yn deall ac yn cadw at eich gofynion bioddiogelwch, dylid adolygu’r rhain a’u diweddaru yn rheolaidd,
* sicrhau bod diheintydd ar gael wrth fynedfeydd eich fferm ar gyfer y rhai hynny sy’n cyrraedd ac yn gadael.

Dywedodd Lesley Griffiths, Ysgrifennydd y Cabinet dros yr Amgylchedd a Materion Gwledig:   

> “Mae’n bwysig i bawb sy’n cadw dofednod barhau i fod yn wyliadwrus am arwyddion o’r clefyd yn eu haid ac i gadw lefelau bioddiogelwch uchel i leihau’r risg o’r clefyd yn lledaenu.  
> 
> “Mae cyfathrebu da hefyd yn hanfodol i reoli’r clefyd ac rwy’n annog pawb sy’n cadw dofednod i hysbysu’r gofrestr ddofednod o’u manylion a manylion eu haid, a’u diweddaru.  Bydd hyn yn sicrhau bod modd cysylltu â hwy ar unwaith mewn achos o ffliw’r adar, gan ganiatâu iddynt gymeryd camau i ddiogelu eu haid cyn gynted â phosib.”

Meddai Christianne Glossop, Prif Swyddog Milfeddygol Cymru:  


> “Er nad yw yr un o’r achosion o Ffliw’r Adar wedi bod yn y DU, mae angen i geidwaid dofednod fonitro eu heidiau yn agos am unrhyw arwydd o’r clefyd.  Yn benodol, trafferthion wrth anadlu, dolur rhydd, dodwy llai o wyau, colli archwaeth a cholli lliw ar y gwddf.  Nid yw Ffliw’r Adar yn glefyd hysbysadwy, ac felly dylid hysbysu’r awdurdodau ar unwaith os oes unrhyw amheuaeth.   
> 
> “Dylai pob ceidwad dofednod barhau eu hymdrechion i sicrhau bioddiogelwch uchel i leihau’r cysylltiad rhwng eu heidiau eu hunain ac adar gwylltion.”
