Hi,

finally we had some discussions with a microbiologist, and the conclusion was using the determination of water activity and using this very low value to prove that there isn't any bacterial growth allowed.
We aren't sure this is 100%waterproof, but it was the best we had.
If you can find a better way, please do post.

Good luck

Ace
