Dr. Paul Corkery:

It is complex. A great deal of onus is being placed on vets in this regulation to prescribe more prudently, especially in terms of antimicrobials. They will not be able to pick the highest priority antimicrobials without a justification. There is much in this regulation that does not suit vets because it is regulating antimicrobials in particular. A vet must now legally provide a justification for the use of certain high-priority and critical antimicrobials. There are two lists. I do not want to make this answer longer than the last one, but there is the WHO list of antimicrobials and a categorisation of them. The European Medicines Agency, through its antimicrobial advicead hocexpert group, AMEG, has set another list of "avoid" medicines, "caution" medicines and so on.
