Well, as many have heard by now, a cow in Washington State USA has tested positive for Mad Cow disease (Bovine Spongiform Encephalopathy) on a screening test at a meat packing plant.
Final analysis and determination of whether the animal is actually infected is being done in Great Britain Laboratory.
As a veterinarian, I thought it might be appropriate to make available some facts about this malady and what the risks may be to consumers of beef and the beef industry.
BSE is caused by a prion. A prion is a sub-viral particle of genetic code too simple to even be considered a life form.
There is exactly one way to catch this disease…that is to eat the under-cooked brains or nervous tissue of an infected animal.
Cows contract the disease in exactly one way, by being fed meat and bone meal (made from infected cows) which has been improperly processed.
The feeding of rendered sheep or beef by-products to sheep or cattle has been illeagal in the USA for some years (especially since we saw what happend to the poor Brits). It cannot be transmitted from cow to cow in any other way.
Cows infected with the disease are entirely unable to play the whistle.
