My name is vinodhini. I am working as an Executive Quality assurance in a mango pulp processing industry.

 

Can anyone help me in understanding the decision tree in HACCP..?

 

 

Best regards,

Hi vinodhini,

 

Thks for yr query and welcome to the Forum ! :welcome:

 

There are numerous haccp Decision Trees of varying complexity/length. The most commonly referenced versions, eg in FS Standards, are probably those due to Codex and NACMCF.

 

I suggest you (initially) view the explanation of the Codex version in the book - HACCP: A Practical Approach by Wallace and Mortimer. A Google books version is accessible on the IT.


Kind Regards,

 

Charles.C

Attached is an example of the two step decision tree that was recommended to me by the tutor on an advanced HACCP course.

 

It is fairly self explanatory , and you use it in conjunction with your hazard analysis.

 

First you identify the pre requisites within your hazard analysis and if a step does not qualify as a pre requisite then you put it through the decision tree to see if it is a CCP.

Annexes items you'll find guides on how to determine the PCC. These articles were published in www.safefood360.com, where you can find more useful references.
 
In the article "Determining Control Measures in HACCP", develops a method that allows you to differentiate a PCC of an operational PPR, which in the traditional Codex decision tree is not possible occurs

Hi jel,

 

Nice papers, thks, but not sure if they answer the OP ? (And same comment to my post also).

 

I guess, as usual, it will depend on what the OP actually wants to know about Decision Trees and maybe for whom will audit ? :smile:

(hint,hint Vinodhini)

 

This (2004) file has a somewhat re-arranged tree to Codex but contains  a neat Appendix discussion over the meaning of the (to me) often confusing bits in the Codex layout.

 

Attached File  simple guide to understanding haccp.pdf   189.09KB   145 downloads

(simple is debatable)

 

Nonetheless, although Mortimore's book's use of the Codex tree at every process step is debatable, it is probably the No.1 bestseller at the moment for (mainly) traditional haccp. Particularly due to its copious and detailed examples plus its clarity of presentation starting from the ground up.

I agree with you that the explanation of the Codex's decision trees is a bit confusing, so books like Mortimer, the item you attached, both I attached, and others, can all provide a better understanding of how to apply methodology of decision tree. Thanks

I personally feel that people over think it. Keep it simple apply the decision tree I posted to each step of your process and you will determine your CCPs., providing you understand what is included in your prerequisite programme, and that's where I think the problem lies.

I really like the straightforward approach you use on the forms you attached.  I've read some HACCP forum topics regarding risk determination: some take the opinion that the risk assessment is supposed to be before the control measure.  Your chart shows the risk assessment following the control measure, which makes more sense to me  -- particularly if you are determining whether a CCP is needed.  Is this how your document should be interpreted?

Thanks!!

Yes, the hazard analysis is laid out so that you think through the sequence logically.

Hi ksullivan,

 

Of course, the control measure may already be being applied. Think cooking.

IMO it's a question of risk assesssment, ie given the process, what further control is required and where.

Some risk assessment techniques specifically do it both ways just to prove that the "added" control works, ie verification.

 

Tree procedures may unquestionably be helpful but their precise implementation is continuously debated. But then again, so is risk assessment.  :smile:
