Dear All,
I previously posted a table of various micro. guidelines for food contact surfaces which were mostly issued pre-2000 at this link –
http://www.ifsqn.com...dpost__p__22352
To update the earlier info., the attached excel file presents guideline data I have accumulated for 12 countries issued in the period 2000 – 2012. The compilation demonstrates that for a range of food-related scenarios, some “average” opinions for various (just) cleaned surfaces are –
(a) For Aerobic Plate Count (APC) - the majority of data suggests that, for routine cleaning/sanitising, surfaces typically have maximum APC counts in the range 10-100cfu/cm2 .
(b) For factors like Coliform, (generic) E.coli, Enterobacteriaceae, S.aureus, the expected maxima are, predictably, low, eg 1-10 cfu/cm2, or undetected. The latter requirement also invariably applies for “zero-tolerance” pathogenic microbial species.
Hopefully of some interest. Further input / comments welcome as usual.
