I think I know the answer to this, but does anyone have any experience using a magnet as a CCP? I can't find any authoritative literature on establishing magnets as a CCP. If it is out there please let me know. Writing food safety program for rapidly expanding business and need immediate input from my expert peeps!

Hi Garderson

 

Yes magnets are use as a CCP control points in various industries. farm based food processing plants. As the raw material for these industries come directly from farms so it possible that nuts and bolts which could come off from farm machinery may be present in the raw material.

 

The high volume retails customers also would like to have assurance that products received by them are free from metal contamination. Here in Australia  all major super markets demand that to have a metal detector at the end of the floor

It depends on the nature of your product, process...etc. If the magnets reduce or eliminate a significant hazard, then it is a CCP. Review your Hazard Analysis. For example in my facility, there is a very low risk of metal contamination in our product, based on our Hazard analysis, history and flow chart. So Metal detector is not a CCP, but we still have it.

Agree with your assessment. My concern is that a CCP must be measurable against the established limits. We are working towards metal detectors as this is a consumer product and the limits are easily identified and adhered to with them. I can't go in front of an auditors and tell them "we know" the metal detector reduces the risk. Thanks for your input, always appreciated.

Have you had issues with metal contamination in the past? If not, and you have record that this has not been an issue for you, then you can ,as The Food Scientist said, use this to show it is not a CCP.

Hi,

 

we are using lots of magnets especially in the incoming of raw materials,but it is never a CCP per definition because we - as a bakery - have 100 % end-of-line metal detection.

In the case of sieves it is different because sieves will remove not only metal.

If you want a reference, can give one model process in "Practical haccp" by Mortimore, a classic, highly-regarded, haccp reference book. Now in IIRC 3rd Ed. This included magnet as CCP together with a metal detector also. Justification is given in the text.

 

As far as "critical limits" are concerned, see parallel thread -
