There is currently no test available to detect CJD before symptoms appear.
Can you get CJD from eating beef?

How long can mad cow disease lie dormant in humans?
Caused by malformed proteins called prions that affect the brain, in cows and humans the disease can lie dormant for a long time before symptoms begin to appear. Some studies indicate that it is possible for symptoms to develop up to 50 years after infection.
