We know that the problem was isolated geographically and that it applied
to a specific period of time. The experts have, for the most part,
retracted their wildest forecasts and are increasingly skeptical that a
pandemic of vCJD will occur.
> or how contaminated the bovine food supply was
Wrong, we do know the extent. We also know that rendering in the US and
UK were different. Since the UK had more cases of BSE early on, and
since the UK rendered those animals, it stands to reason that rendered
feeds in the UK would have a greater rate of contamination. The other
nations with significant cases of BSE imported cattle and feeds from the
UK. The US was not a big importer of either UK feeds or UK cattle:
BSE has not occurred in the United States or other countries
that have historically imported little or no live cattle, beef
products, or livestock nutritional supplements from the UK. Even
though rendering procedures in other countries underwent changes
similar to those in the UK during the late 1970s, BSE has
apparently emerged solely within the UK. The most plausible
explanation is that the proportion of sheep in the mix of
rendered animal carcasses and the proportion of scrapie
infections in such sheep were probably higher in the UK than
elsewhere. These proportions were apparently sufficient to bring
very low levels of the etiologic agent in batches of rendered
carcasses over the threshold of transmission in the UK but not
in other countries.

> and is for how many years.
The window isn't unlimited. Researchers are increasingly skeptical there
will be a pandemic or even significant increases in the number of new
cases because the data don't support it. The actions taken early on in
the UK -- specifically banning feeds made with rendered ruminants --
coincide with a peak of cases. Since that time, new cases have fallen
quickly.

The window from time of infection to detection appears to be within a
decade. Some new cases may occur from infection via blood transfusion,
medical instruments, etc., but the food supply has been shown to be very
safe.
