Very interesting discussion, Charles, thank you!
How do you look at this: can one make baking as oPRP?
My justification: although it is a temperature-controlled process, normal baking temperatures of low-moisture foods are a huge overkill from in the aspect of pathogen preservation in the product. We speak about programs that operate at least 30 degrees on top of what is needed for killing the pathogens. Also a hypothetical failure, when pathogens could survive because or oven´s malfunction would result in obviously under-baked products.
So, could it be solved as a periodic control, if the oven´s thermometers are calibrated?
Hi dohh,
^^^(red) - Baking is undeniably a source of frequent haccp debates.
JFI I should point out a few initial debating points -
(1) Many, but definitely not all, texts consider the baking step as not being associated with any significant hazard. In which case, neither a CCP nor an oprp exist. (The "visibly unbaked" argument was, IIRC, included in a near-final draft of iso22000:2005 but got deleted from the final version for unspecified reasons).
(2) The relevant hazard/CCP reference point is the product core temperature so that above mention of + 30degC (I assume "C") as typical may not always be valid.
(3) Contrary to (1) above, the interpretation of baking as a CCP is supported in FSMA's "HACCP Program" via a specific example in FDA's draft Hazard Analysis / Preventive Controls Guidance. (This analysis rebuts some earlier baking FSMA speculations, eg -

Regardless, i assume for present purposes that the baking step is associated with a significant pathogen hazard, eg Salmonella spp, B.cereus. Accordingly it is necessary to apply a logical decision methodology to determine whether the associated control measure (temp/time) is a CCP or oprp.
One possible decision tree (of many) is attached in post linked below (also assuming the additional textual caveats). Alternatively one could apply the more exhaustive excel method given in Post 22 of same thread.

Both decision routes indicated a CCP for me.
