Cafodd yr IAA ei sefydlu yng Ngogledd Sir Benfro yn 2010 fel ardal ag iddi fesurau llymach ar gyfer mynd i'r afael ag achosion TB Gwartheg. Mae'r mesurau hynny'n cynnwys mesurau rheoli gwartheg, mesurau bioddiogelwch gwell, brechu moch daear a phrofi geifr ac anifeiliaid o deulu'r camel. Dyma drywydd newydd i'r DU.
The IAA was established in North Pembrokeshire in 2010 as an area where increased measures would be applied to tackle all sources of bovine TB. These included stricter cattle controls, improved biosecurity, badger vaccination and testing of all goats and camelids. This is an approach which has never been tried before in the UK.
