Hi

Thanks for the info. Good to see our country features on the list. The problem that I have with our legislation is that it does not specify pathogens. So what happens is the allowed 100 CFU happens to be Listeria?

It's a good consideration.  However, I think these guidelines are generally for validation of cleaning. If you are RTE and have a Listeria concern, you should also be doing in-process testing and/or finished product testing, which would tell you whether or not you actually have a Listeria problem. 

 

Edit: I should add that if you are RTE or similar, you should also be doing environmental monitoring for pathogens such as Listeria.

Hi Cobus,

 

Just for accuracy, I suspect 100cfu(/gm?) is unlikely to refer to Listeria. Possibly L.monocytogenes.

 

And, similar to MsMars comments, the "100cfu" probably refers to a product, not a surface ??


Kind Regards,

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 ,

 

Do you have an update this file ? 

 

Hi Naamfon,

 

Not a global one although I and other people have added a few more recent documents here and there. For example there are some "relatively"  recent and quite interesting documents (eg Posts 6, 8, 9) in thread linked below.

 

https://www.ifsqn.co...es/#entry168373

 

I suspect there have been few major changes/unifications since my 2012 survey, eg one can still find recommendations for APC counts to be less than 2.5 and 100 cfu/cm2 respectively :smile:


Kind Regards,

 

Charles.C

Dear Charles,

It was a great source of guideline. Do you have any updated version of the same.

Thanks in Advance,

Good day sir Charles!

 

Thank you so much for that file, it really is a big help for my thesis. 

May I know the full details or references about Willis (UK - 2012) and Little (UK - 2006/2009)? I would just like to cite it in my literature.

Hoping to receive a reply from you as soon as possible.

 

Once again, thank you sir. Have a great day ahead!

Correct me if I'm wrong, but are these the references that I was asking a while ago, sir? I have managed to trace it from the links posted here :))

 

Willis C, Elviss N, & McLauchlin J. 2015. Follow-up study of hygiene practices in catering premises at large scale events in the United Kingdom. Journal of Applied Microbiology 8(1):222-32.

 

Little C and Sagoo S. 2009. Evaluation of the hygiene of ready-to-eat food preparation areas and practices in mobile food vendors in the UK. International Journal on Environmental Health Research 19(6):431-43.

Hi Joyce,

 

Regret I don't offhand recall the original refs.

The excel was posted in forum in 2013 so 1st reference in yr post (ex 2015) not likely to directly match.

However it is quite possible that the material in dates shown in my excel was republished in later documents. (Indeed the data in yr 2015 ref looks unchanged although slightly expanded as compared to that [2012] in the excel).

Hi Charles,

 

Good day!

 

I would like to ask if you have a microbiological criteria for fcs? I am now doing a criteria for micro in fcs.

 

Thank

Hi microlab,

 

Not quite sure what you mean ? Isn't that the objective of the previous posts ?
