Thanks for the feedback. I appreciate you are bound by US limits.
I have done a little searching through the forum for items relating to micro. properties of packaging. Data is scarce.
I suggest you have a look at this post where I previously summarised some of a similar scan -
Probably 1st, 2nd and last links are of most interest for present purposes.
From a quick look, the US bacterial count limits are slightly generous compared to some other localities.
The only data for yeast & mould (Y&M) I could see was in post #4 of the last link. Hopefully of some use. (There are a large number of attachments in these links so I maybe missed something else ).
