Hello Carmelo, 

Nice to meet you ! 

Well Validation easily is how to ensure that this machine or step is suitable for your process , so you need at first to :

1. Mention the hazard that you need to remove, detect or Eliminate.

2. Prove that this metal detector is suitable for your industry ( it will be into the manual of the metal detector or on their site).

3. Mention the need that makes you pick up this type ( which is removing the type of different metal with size 2 mm).

4. Mention reference that you are working on.

5. Mention testing of metal detector not less than 10 times on site and it should be continual positive (10 times working positively), this to be made for every MD if you have many.

6. Mention the Monitoring , Verification intervals and who is the responsible according to your HACCP plan.

7. Team of validation shall include (area owner (operation or production team), QC, QA or food safety).

 

Hope that i help you, please if you have any inquiry don't hesitate to send me.

Hi Carmelo,

 

The answer may depend on what clause in SQF is involved ?

 

If you are talking about haccp, it probably means validating the  critical limit  for the detector when set as a CCP.

 

See this recent thread -

Hi, Carmelo.

 

You can combine CAC/GL 69-2008 (for the "foundation) and what is stated on your equipment manual. Normally, on the last page, there is always a description on how it should be set-up. If the organization don't have the experience yet, you may seek your equipment provider assistance provided that you discussed thoroughly with him what are your expectation and limit for the contaminant (Fe, nonFe and SS). On their equipment, they normally state 10 passes, but CAC/GL 69-2008 requires statiscally sound repitition which can be from 30-50 passes.

 

There are some prerequisites before they do this (especially if this is new to the team) such as:

 

Vibration check

Electromagnetic interference check

Product effect  (including distance between product)

 

Then after all settings are established, perform challenge test such as successive contaminants etc..

Hi Carmelo,

 

The approach I took was to produce a response curve for each type of test piece using test pieces of different sizes, passing each test pieces through multiple times.

 

Then taking determining the background signal of the product(s) a practical critical limit is established based on the mimimum size test peice that gives repeatidly reliable detection vs the product background signal. If you can use  a statistical approach to establishing the limit using the standard devitiation.

 

Document it.

 

We produce additives for the animal feed industry and during the audits by FAMI-QS has had positive observations.

 

Regards

 

John

Hi John,

 

I would add that as discussed in previous threads here, the Validation may also involve aspects such as test piece traceability/material, Geometry of MD Coil array, food matrix effects, test piece location, item(s) separation, etc.

 

Technically/Statistically one may also be confronted with terms like LOD, LOQ.


Kind Regards,

 

Charles.C
