Giant anteaters are everywhere now, compared to just london around ten years ago. Before that, until the start of the 90's, only London and Kilverstone kept them (when the runs were opened up into paddocks in the stork and ostrich house London stopped keeping them for around 12 years, and obviously Kilverstone closed). I think you can see them at Amazon zoo world, edinburgh, marwell, howletts, London, colchester......
Tamaduas looked like they were going to become well established for a while, now they are all the sothern subspecies with the exception of a northern at howletts and another animal of another subspecies at Amazon zoo world. Only a couple of zoos now seem to have pairs, if ISIS is to be believed, and I don't think there has been any breeding for a little while. I do know that RSCC acquired at least one, either to quarantine for colchester or to keep themselves. Their website list them as keeping this species but they don't show up on ISIS.
