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.

dear charles.c,

 

Thanks for your information. anyway, what is the limit range for those in used equipment?

 

For coliform and e.coli, do we have the standard in MPN unit?

Dear khc,

 

Yr first query is sort of unanswerable without more context. For example, Cleaned/sanitised, uncorroded, SS tables should be equatable to the the broad APC ranges mentioned. Presumably if you spend all day C/S, the results may be better. :smile:

 

Yr second query will depend on the method of course. I don't remember seeing any dilution-type data for the limits quoted but not impossible. For cleaned situations, the E.coli, S.aureus limits  are often simply "not detected/given area".

Hello there!!! I'm new around here, and I have some doubts...

I've seen in some articles (here in Brazil, mostly) that APHA's guidelines for microbiological contamination of hands and 

surfaces that could be in contact to food can't get above 10^2 CFU/sq. cm. 

However, I've not found this information right from the source, I mean directly from APHA.

I can't find any document that could embase my researches.

I work at a milk processment industry, and we are determining the parameters for monitoring it,

and I need to embase the informations I'm gonna use.

 

Could someone show me the web adress, or post any document that I could

to use for this purpose?

 

Thanks,

 

Marciel

Hi there....

I am searching for EU limits for TVC of surface swabs and hands.

Any EU guideline or regulations which i can refer for food contact surfaces/hands? 

 

thanx

Dear ablho,

 

As suggested by data in post #1, i think there are no official EU-wide limits. Like most other diverse areas.

 

The nearest equivalent used to be some APC / coliform limits for meat processing tables but i think subsequently rescinded.

Hi Thank you for the standard.

The excel that you gave is really helpful, do you have references for that so that we may read about it.

 

I really need where that references comes from.

 

 

Wishing you all will reply :)

Charles,

May I ask what is your background in the field?

I am using the reference materials you have posted as our internal reference for QA department. Thank you!
