Mae'r mesurau hyn ynghylch siediau yn ychwanegol at y rheoliadau bioddiogelwch cryfach a gyflwynwyd fel rhan oBarth Atal Ffliw Adar (AIPZ)ar 11 Tachwedd. Mae'r Parth hwn yn golygu bod angen i geidwaid dofednod ac adar caeth gymryd rhagofalon ychwanegol fel glanhau a diheintio offer, dillad a cherbydau, cyfyngu ar fynediad pobl nad ydynt yn hanfodol ar eu safleoedd, a gweithwyr yn newid dillad ac esgidiau cyn mynd i mewn i amgáu adar.
These housing measures build on the strengthened biosecurity regulations that were brought in as part of theAvian Influenza Protection Zone (AIPZ)on 11 November. The AIPZ means that all captive bird and poultry keepers need to take 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.
