Abstract:

New Zealand is free from bovine spongiform encephalopathy (BSE), classical scrapie of sheep and goats, and chronic wasting disease of deer (CWD).

This change in status, although not entirely unexpected(2), has still required work to clarify the relationship between classical and atypical scrapie. MAFBNZ strongly supports the view of OIE that atypical scrapie is “clinically, pathologically, biochemically and epidemiologically unrelated to “classical” scrapie, may not be contagious and may, in fact, be a spontaneous degenerative condition of older sheep”(3)...
