This is an interesting editorial about the Mad Cow Disease debacle, and it's ramifications that will continue to play out for decades to come. I thought Professor Budka said it well. ...

EFSA Journal 2011 The European Response to BSE: A Success Story


snip...


EFSA and the European Centre for Disease Prevention and Control (ECDC) recently delivered a scientific opinion on any possible epidemiological or molecular association between TSEs in animals and humans (EFSA Panel on Biological Hazards (BIOHAZ) and ECDC, 2011). This opinion confirmed Classical BSE prions as the only TSE agents demonstrated to be zoonotic so far but the possibility that a small proportion of human cases so far classified as "sporadic" CJD are of zoonotic origin could not be excluded. Moreover, transmission experiments to non-human primates suggest that some TSE agents in addition to Classical BSE prions in cattle (namely L-type Atypical BSE, Classical BSE in sheep, transmissible mink encephalopathy (TME) and chronic wasting disease (CWD) agents) might have zoonotic potential.

see follow-up here about North America BSE Mad Cow TSE prion risk factors, and the ever emerging strains of Transmissible Spongiform Encephalopathy in many species here in the USA, including humans.

Transmissible Spongiform Encephalopathy (TSE) Prion Disease, aka mad cow disease, are emerging in more ways than one, and the risk factors there from are very disturbing. The TSE Prion disease has morphed into many different strains, and in some cases, with Co-occurrence of multiple Prion Protein Types in one recipient. There are now many more strains of BSE aka Mad Cow Disease, what are termed 'atypical' BSE. atypical BSE is more virulent than the typical UK c-BSE. L-BSE, H-BSE, along with the U.K. C-BSE, have all been documented in North America (IBNC prion disease in cattle has not been documented in North America to date), along with two different strains of Chronic Wasting Disease (CWD) in deer and elk (documented to date), and many typical strains of Scrapie in sheep and goat, with the atypical Nor-98 Scrapie documented and spreading in North America. Over time, all these different TSE prion disease have been rendered and fed back to food producing animals here in the USA. The August 4, 1997 partial and voluntary mad cow feed ban in the USA was nothing more than ink on paper. The Bovine Spongiform Encephalopathy (BSE) aka mad cow disease surveillance program of the USA was terrible flawed (see GAO, OIG reports), and the BSE testing program was just as flawed, and this all a proven fact. With the mad cow feed ban having not been enforceable, 100s and 100s of TONS of banned MBM went on to be fed to USA cattle a decade after the August 4, 1997 partial and voluntary feed ban for BSE was inked on paper. Today, the USA has no idea (in my opinion), just how bad the BSE aka mad cow disease really is. However, the USA has more documented TSE prion disease in different species in the wild, than any other country, all rendered and fed back to food producing animals for man and animal. sporadic Creutzfeldt Jakob Disease in humans, with unknown pathology is rising in the USA and Canada. I urge Science to move forward, leaving the politics behind $$$
