Dear hygienic,
Example; I have sandwitch and I want to do the micro tests for it , by schedule I want to make some specific tests for the said product , I mean can not do salmonella or Bacillus test daily , but TPC and E.coli are mandatory daily for any kind of products collected for the analysis , this why I want to make schedule to avoid the confusion.
what do you think ?
It depends on the kind of queries i put in previous post, eg specifically what your products are, how much of them, why you are selecting the items you mention above to focus on, etc.
For example, to illustrate the width of the choice, I am guessing the most common basic set of internal factory lab. micro. measurements per sample is -
APC, coliform, (generic) E.coli, Staph.aureus coag+, Salmonella.
plus, depending on technical facilities / products / customer / legislation / etc, a few more may be done, eg Enterobacteriaceae, E.coli O157, L.monocytogenes, "vibrio" members, "bacillus" members, and others. many labs do not have the expertise or the wish to do many of the second group so prefer to send samples to external labs.
I hv visited some factories which are running up to 7 or 8 of the above parameters on more than 10 new samples every day. This creates a prodigious workload, especially if not using any rapid detection kits / systems. The primary reason is pure business, eg customer requirements for a full COA for every lot (day) code. Such a situation almost makes a nonsense of maintaining a
haccp system IMO.
I do not have a food microbiological analysis procedure in my place , do you think I need to fix a written procedure ?
Yes, it is a prerequisite. Together with acquiring a food microbiologist.

And maybe a lab.?
(I recall you hv previously sought guidance on where to find the procedures

)
