It may be something to do with mad cow disease or HIV, also I think its only if you have received blood between 1980-86 that you can't give blood.

Mad Cows Disease or in humans Creutzfeldt-Jakobs Disease eats your brain.
Not always FAST. So, these people, in most other countries associated with cannibals because you can only get it from eating the Brain Tissue. However, meat packing and greed being what it is, sometimes the two get mixed to make more "meat weight." When this is eaten by a human, it can take decades to cause its worst damage. If eaten alot, it acts much faster. However, it destroys the myelin and nerve compounds around the sheaths and exposes them to the brain. This ends up destroying them, causing neurological diseases such as shaking and blindness.
Since its so small that it can already cross the Blood/Brain Barrier (between the brain and the body) it is automatically assumed that it is in the blood stream. And I'm sure it is if it can make it through the Blood/Brain Barrier.

Because there is a perceived risk of disease, although it is arguable that the risk is negligible. There is no such restriction within the UK.
The fatal prion cattle disease BSE inadvertently became quite widespread in Britain due to changes in the way animal feed was prepared. The disease was not properly understood and controlled for some time, allowing contaminated meat into the human food chain. It was later realised that eating such meat gave rise to a (very low) risk of contracting a human form of BSE, called vCJD, also a fatal prion disease, which takes years to develop, and it is thought possible it could be communicated via blood.
The total numer of confirmed and probable deaths from vCJD in the UK to date is 158, the number of cases per year has fallen sharply since 2003, and it is estimated that there are only about 6 more such cases to follow in due course.

Any person who travelled to Britain between these dates could have contracted contracted CJD from infected meat. Anyone who received a blood transfusion before 1997 in Britain can also not donate blood.
Likewise any British person who has had a blood transfusion can no longer donate. I had one last year and am not allowed to give blood anymore.
