Dear All
I am new to this forum, and I find it really useful :)
I am working in UHT plant for beverage (milk, juice) and we are preparing for ISO22000 now.
Rather confused with how we are going with validation & verification of CCP against micro hazards
Our micro data so far is mostly about total plate count, spore count and doesnt include testing for pathogenic microbes, so i am not sure how we can use that data
doing challenge testing is not an option because it is too risky
anyone can share your opinion?

Thanks alot
Sandra

IMO.. you can compare micro contain in product betwen before and after UHT.. Sterilize is success, if that process can reduce ± 90% ( 1 log) micro... thats mean if the micro before UHT is 100 CFU, after the process it have to less then 10 CFU... I thin that is simple method to validate uht process...

HOpe can help you...

Dear AZ NUR,

For once, don't quite agree with yr answer logic .

I think you have to specify the process / hazards first. For sure, milk will not be the same as fruit juice.

The (usual) microbiological hazards are ???

Personally I would then do some literature reading up for the process.

Then "justify" the control step action (ie validate), ie how it reduces the hazard(s) to an "acceptable" level. ??

I don't know much about UHT but a 1log reduction seems a very low target. Is this typical ? Based on ?
Eg, I noticed this link - http://www.cfsan.fda...eman.html#chap9

But maybe the situation is different ?
