Nobel Prize winning prion expert Stanley Prusiner says all cattle should be tested
for prions.

But if prions are so common in cows and are a threat to humans then why aren't they
causing more human disease? Or is there about to be a human outbreak in the US after
gestation time from infections that started in the mid 90s? But even if so have feed
practices now so reduced the risk of new infections that there is no point
in testing?

If current cow feeding practices are still a threat then doesn't a change in feeding
practices make more sense than widespread testing? Why should cattle become
a permanent threat to health as carriers of dangerous prions if they didn't
used to be
a threat in the past when human prion disease was rare?

    Excerpt:
Early this fall, Japanese surveillance found two new cases of the disease in young
animals, aged 21 and 23 months. "Under no testing regime except Japan
would these
cases ever be found," he said.
