The slide was presented at the 2000 Conference on Microbial Control hosted
by AAI.

Good to hear that this proposal is no longer active.  Thanks,

Wow!

This is the problem with presenting information on ongoing projects.
This position fell through on further discussions when it became
apparent that there was no way to "grandfather" products.

You neglected to mention the year that slide was presented, I would
imagine that it is at least 3-4 years old as the recent history of the
harmonization effort in microbiology has not been nearly so hopeful.
It is difficult to come to common ground when one party to the process
repeatedly reverses agreements and insists that theirs is the only
valid position.

We may never see a fully harmonized PET or Sterility test, but at
least the last 6 years have brought the methods somewhat more in line.
