Secretary Johanns' strong agricultural roots stretch back to his childhood. He was born in Iowa and grew up doing chores on his family's dairy farm. As the son of a dairy farmer, he developed a deep respect for the land and the people who work it.
Days after he took office, he began working with U.S. trading partners to reopen their markets to U.S. beef. Nearly 119 countries had closed their markets after a single finding of a BSE-infected cow in the U.S. in 2003. Within his first year, Johanns convinced nearly half that number to reopen markets.

"Those who are trying to convince their consumers that universal testing or 100 percent testing somehow solves the problem really are misleading you," he said.
"Consumers should feel better than ever about the meat that they are buying," Johanns said.

Johanns said Japan, which has found 27 cases of mad cow disease, definitely has a problem with mad cow disease.
In contrast, the United States has a much larger herd of cattle and has found three cases of the disease: In December 2003, in a Washington state cow imported from Canada; last June, in a Texas-born cow; and in March, in an Alabama cow.
Senators Slam Voluntary Bird Flu Testing in the USA
Senators on Friday criticized the Agriculture Department's planning for deadly bird flu, saying the voluntary nature of its testing program threatens the U.S. poultry industry.
At issue is a federal audit that found the government lacks a comprehensive plan for testing and monitoring bird flu in commercial poultry.
The incubation period in cattle is usually 2 1/2 to 6 years, so the peak of disease
occurs in cattle 4-5 years old.
.....
Because of the long incubation period, infected cattle have rarely been found at
less than 30 months of age.
....
Most cattle are slaughtered at 12-18 months of age.
However, the United States argued that the testing of young cattle – less than 20 months of age was unnecessary. BSE does not infect young animals.
One estimate is that current test methodology would have a false negative test rate of 92% for clinically normal adult cattle because prion accumulation is lower than the detection threshold (i.e., if 100 BSE-infected adult cattle were tested while clinically normal, 92% of them would test negative even though they were, in fact, infected).

However, it also looks like the govt has figured that since we have no accurate tests....
Newer tests, by a variety of companies, are more sensitive, cheaper and faster. Dr. Prusiner said that his test could even detect extremely small amounts of infectious prion in very young animals with no symptoms. Sold by InPro Biotechnology in South San Francisco, a single testing operation could process 8,000 samples in 24 hours, he said.
It can take up to 50 years for symtpms to appear in humans....

so as you can see, there seem to be such tests. So why aren't they using them?

Not exactly. its between 8-10, but there have been rare cases of up to 20 years.

HMMMM. I wonder.

Oh yeah. Maybe for the same reasons vaccine manufacturers don't test for prion
contamination even though cattle products are used in the vaccine-manufacturing process:
1. There are too many different prion strains;
2. Existent prions morph into new strains at the drop of a hat, like with a shift in temperature;
3. Vaccine manufacturing and food processing actually create new prions;
SO
4. There is no point - you'd identify 3 or 4 known strains, but you'd miss the rest -
Mad Cow/BSE is just one of Gawd-knows-how-many prion strains now loose in the world.
(And yes, I do have a reference for this info, somewhere - but try Googling
*Mad Cow *FDA *committee *vaccines)

Stanley B. Prusiner, who won a Nobel Prize for discovering that prions cause transmissible spongiform encephalopathies (diseases such as BSE and CJD), also argues that all cattle carcasses should be tested for BSE. The disease is generally thought to arise from eating infected meat and bone meal, he explains, but isolated cases could occur spontaneously, just as prion diseases arise spontaneously in many mammals--humans and sheep, for example. He also claims that 30 months is an arbitrary cutoff age for testing. Although BSE symptoms do not appear until after 30 months, the animal may be infective long before then, he explains.
The cost of testing all cattle would be very low, only a few cents per pound, compared with the danger of not testing, Prusiner says. At a May hearing before the California Senate agriculture committee, he used an analogy: If there were two ticket lines at an airport and one guaranteed you would get to your destination safely for $1.00 extra while the other line offered no guarantee, most consumers would pay the extra dollar. Similarly, he expects that most consumers would be willing to pay a few extra cents per pound for BSE-tested beef.
Prusiner notes that he has studied prion diseases for two decades, but there is still a great deal that isn't understood about them. At any time, a new strain of BSE prions could develop that is more infective for humans. "Only the Japanese solution of testing every slaughtered cow or bull will eliminate prions from the food supply and restore consumer confidence," he says.
But what Prusiner believes is that an acceptable expense is considered unacceptable by NCBA. NCBA argues that the cost of testing every slaughtered animal would be "huge"--about $30 per animal. Since about 35 million cattle are slaughtered each year in the U.S., the total cost of a universal testing program would be more than $1 billion and would increase beef prices by about 5 cents per lb, NCBA claims.
John Stewart, chief executive officer of the meatpacker Creekstone Farms, says the major meat processors--the four corporations that process more than 80% of U.S. beef--don't want to test all their beef because 4 or 5 cents per lb to a commodity packer is big money. "Commodity packers basically believe they can't move extra costs up the food chain to the consumer," he says. "So they end up doing one of two things: reducing their profits or moving those costs down the food chain to the cattle producer," he observes.

What we should be focusing on is not a vaccine, but detection to just get rid of it. Isolation is a way to avoid it spreading. A vaccine to me is not worth pursuing. Detection is.

yes but I mean like screening test, not test to rid the prions. Dont create anything that modifies it, just spots it better. To the point where as soon as it appears, we can see it and isolate that animal so it doesnt infect others.

Testing was only smoke an mirrors anyway. The source of the disease is everywhere, even in your carrots and cabage. The entire food supply is contaminated beyond repair. From milk, to fish, to the apple in your lunchbag.

Authorities are afraid that if the FDA enforces universal testing using sensitive tests then everyone will know that Mad Cow is everywhere. Same with bird flu.
Points being:
1. Mad Cow did not start with cows, just like bird flu did not start with birds;
2. There no longer is any point isolating the "infected animal" - because prions don't just cross species barriers, they cross kingdom barriers.
