So Tam, I guess you know more than this guy:
Prusiner also contends that the rapid diagnostic tests, which are proving useful in the mass screenings in Europe and Japan, still have limitations. They depend on dangerous prions accumulating to detectable amounts – quite often relatively high levels in an animal's brain. Yet, because BSE often takes three to five years to develop, most slaughter-age cattle, which tend to be younger than two years, usually do not test positive, even if they are infected.
According to Prusiner, because of the limitations of the existing tests, developing one that is able to detect prions in the bulk of the beef supply – that is, asymptomatic young animals destined for slaughter—continues to be one of the most important weapons in confronting prion disease outbreaks.
"Given that seemingly healthy animals can potentially carry pathogenic prions, I believe that testing all slaughtered animals is the only rational policy," Prusiner told Scientific American in the July issue. "Until now, the tests have been inadequately sensitive. But the advent of rapid, sensitive tests means universal screening can be the norm. I see no other option for adequately protecting the human food supply."
If the market (Japan) demands it, and customers are willing to pay for it, then we should be allowed to do it. Our goal is to quickly help open up the Japanese market. Our decision is similar to some rancher's decisions to sell organic or natural beef. Certain customers will pay for it even though there is no scientific evidence that "natural" or "organic" beef is healthier than conventionally produced beef. This, combined with the fact that not enough is known about prion diseases, is reason enough to allow for private testing above and beyond USDA plans.
If more were known about the science of prion diseases in animals and humans, a more balanced and acceptable science-based regulatory approach might be attainable. In the absence of such knowledge, when a Nobel Prize-winning researcher, one of the most respected authorities on prion disease in the world, believes in 100 percent universal testing, then perhaps that's justification enough for the USDA to allow Creekstone Farms to test.
Hey Tam, Guess who was the keynote speaker at the OIE/TSE Conference last year?
