[QUOTE="Anonymous, post: 16363"] Ok, I don't live in Britain, so I'm going on published data, not personal experience..... BSE is transmitted by a bovine eating infected material--namely a prion--which originated in a sheep with scrapie. (if I'm wrong, please correct!!) The meal from this sheep, when fed to the cow COULD, not WOULD infect the cow. There is a 3+ year incubation period (thus eating animals less than 30 months of age should not be able to be infective to humans) I do not know the odds of this feed infecting the cow, but the theory I read was that only 1 in 1000 or less would get infected on the same contaminated feed on average(number of feedings was not named). So, if your chicken is contaminated with the prion, you have less than .1% chance that each individual animal would be infective. The two paths to take from there are either to keep any and all cattle from eating chicken feed, or only have chicken feed without animal protein or fat... There is no ability to diagnose in a living animal. A presumptive diagnosis based on clinical signs would be followed by a definitive diagnosis based on histology etc of the deceased animal's brain..... Did I clarify or muddy the answer? V [/QUOTE]
