The incubation period for vCJD could be as long as several decades (30 years). The UK has put in stringent Laws and regulations to exclude bovine neural tissue and contaminated meat from the food supply. More has been done to ensure the safety of medical products, like bloods and derivatives for transfusions.

I can see an epidemic of vCJD, or another equally horrific disease, caused by the lack of testing and regulations on products which open a 'back door' to infection.

To clarify the severity of vCJD:
