Can you possibly complete a risk assessment and determine that you do not need to inventory knives daily?
We have metal detection on all lines, one line has detected a very small piece of foil in an ingredient. Is it possible to use our past metal occurrences to justify not having to inventory the knives on a daily basis?
As you are concerned regarding SQF requirements:
188.8.131.52 Knives and cutting instruments used in processing and packaging operations shall be controlled, and kept clean and well maintained.
Guidance 184.108.40.206 Knives and cutting instruments must be counted and controlled and kept clean to avoid cross-contamination.
So a frequency is not stipulated. For me there are a couple of things to consider in deciding a frequency that is adequate?
The type of knife used and risk of the blade snapping
The risk of it ending up in the product (whole or part)
Your ability to take timely corrective action if a knife or part of a blade is missing - Assuming the metal detector will detect a whole knife what action do you take when one is missing?
What size of a snapped blade your metal detector will find
Since some of your products are RTE I assume they go out PDQ. You have to ask yourself if you check your knives less frequently than daily and you find a problem what are the repercussions? A product recall?
