Thank you Charles.
I think I can adapt the Risk Assessment in the first link to match our materials/process. In addition, we can swab for Enterobacteriaceae + Y&M on some finished goods and direct contact areas on some equipment as discussed with our auditor to back up our assessment as being low risk. Does this sound reasonable?
I am assuming the testing we perform for Enterobacteriaceae + Y&M would be accomplished through swabbing only. The labs I have contacted previously would not offer any general help or guidance as to what would be acceptable or a standard test as it was on the fringe of "consulting".
Are there any general parameters I can measure our test results against ?
Most published data is for food contact surfaces. A compilation is here -
There is some packaging env. data in threads linked in post 2.
IIRC the 2nd file in this post is quite env. useful as are attachments in surrounding posts for the packaging itself -
The expected levels for things like APC, Y&M, Enterobacteriaceae for a packaging facility will presumably be low, hygienic factors are likely borrowed from food and will again be low.
PS - I did a very mini forum survey in 2018 which see here -
within above survey I noticed a modicum of data-related here -
